Oxa’s customers are the operators of some of the world's largest industrial facilities. Our technology transforms existing industrial vehicles into intelligent autonomous fleets, unlocking new levels of productivity, safety, and performance. ‘The phone in your hand, the coffee on your desk, the shirt on your back - they all moved through a web of ports (air and sea), distribution yards and manufacturing hubs. This is the invisible circulatory system of global trade, and it relies entirely on a relentless, repetitive shuffle of goods. Towing. This towing task happens in complex, commerce-critical industrial environments. Here, having self driving technology “do the driving” delivers immediate, measurable impact. IMA will revolutionise the movement of goods across the world's ports, airports, and yards. You can be part of that as an Oxbot’ ‘Paul Newman - Founder and CEO’ Our Products: Our products are built on four core technology pillars which come together to build a complete system: Oxa Ware – Our modular autonomy hardware systems for consistent and repeatable integration of autonomy with existing vehicles. Oxa Driver – Our Physical AI, embodied in Oxa Ware, self-driving software that enables vehicles to perceive, reason, and drive autonomously in complex real-world environments. Oxa Foundry – Our development toolchain that leverages generative AI to continuously train and assure Oxa Driver, synthesising situations and sensor data. Oxa Hub – Our suite of cloud services for monitoring, managing and orchestrating fleets driven by Oxa Driver, including an API for integration with existing logistics systems. Behind these technologies is our exceptional team, the Oxbots. We are home to some of the world's leading experts in autonomous systems, robotics, machine learning, artificial intelligence, cloud infrastructure, and distributed software engineering. Together, we're solving some of the hardest technical challenges in autonomy, turning the research and development we do into production and deploying it into environments. Making robots do useful work. Launchpad is where autonomy meets the real world: covering integration, commissioning, testing, and initial deployments. We love flexible engineers who enjoy stepping out from behind a single domain to tackle every layer of the problem—whether that’s tweaking code, troubleshooting hardware in the field, or getting a vehicle running smoothly on-site. As a member of Launchpad you will acquire a comprehensive understanding of the system’s components and interactions, identifying the areas for improvement and acting as an initial customer to drive our technical capabilities forwards. We are a team of problem solvers and keen roboticists who enjoy looking at the big picture and tackling challenges, and we are devoted to perfecting our software both in the real and the virtual worlds to deliver the best possible version of our vision for Universal Autonomy. Full-Lifecycle Engineering: Bridge the gap between software development, hardware integration, and real-world execution. You’ll own problems end-to-end, moving fluidly between systems engineering, software diagnostics, and physical setup. Real-World Application: Get hands-on with cutting-edge field robotics deployed alongside major global partners in airports, ports, and industrial yard operations. Global Exposure: Based in the UK, with exciting secondment opportunities to work on-site with our partners in the UAE. You’ll build the tools, not file tickets for them. The software our field engineers depend on is written by the people who need it — a viewer for every sensor and subsystem, a commissioning GUI, log-snipping and replay tooling, and automatic code change management. There's no separate tooling team to hand problems to. When a capability falls between two teams and nobody owns it, it becomes ours to write. We built our own factory to develop robots in. A mock industrial site on our own test estate — real vehicles, real workflows — where autonomy runs daily, unsupervised and where every new feature gets proven first. Bare metal to driverless. Bringing up a new vehicle tests every assumption in the stack at once — network, sensors, controllers, calibration — and the real work is diagnosing why it doesn't come up. You'll be the person who traces a fault across the hardware–software boundary, finds the actual cause rather than a workaround, and then makes sure the next vehicle never hits it: fewer manual steps, better checks, days instead of weeks. AI is in our workflow, not our pitch deck. LLM coding assistants are standard issue here, and every merge request can get an automated review before a human sees it. We point models at the product too — automatic code change generation from release diffs, ML-based scenario recognition, telemetry-first triage of field issues. Some of our most interesting open threads are agent loops that take an operator's report of an autonomy issue and iterate towards a fix. Work as part of a cross-functional team in the field to operate, test, and debug our autonomy systems in the real world. Build, upgrade and maintain maps for testing our vehicles in the real world. Investigate and analyse data to enable issues to be identified and resolved. Work collaboratively with multi-disciplinary (and multicultural) teams, communicating technical requirements and working together to find solutions. Identify functionality gaps, contributing to the development of hotfixes and new features. This is a hybrid role which will require working hands-on with autonomous vehicles. This role will require extensive travel to the UAE for seconded periods of time. Candidates must have no restrictions on their passport preventing entry into the UAE and no criminal record. Strong problem-solving skills, particularly working with hardware and across the hardware-software boundary. Process development, with a focus on creating reliable, streamlined workflows that others can easily scale and follow. Able to manage workload and adapt quickly in the face of physical build and schedule challenges. Able to work flexibly with shifting priorities in a fast-paced environment. Able to capture software and process requirements, translating them into reliable tooling and workflows. Able to plan and coordinate the delivery of projects with multiple stakeholders across different teams. Familiarity with the software development process, particularly in scripting, automation, and building internal tooling (e.g., Python/Bash). Working knowledge of C++, ROS or equivalent middleware, Linux, and git/CI — enough to navigate and debug an unfamiliar robotics codebase rather than waiting for its author. Ability to work in multi-disciplinary teams, communicating technical requirements effectively with software, hardware etc. This role requires regular presence in our Oxford workshops and test sites to capture requirements and develop a hands‑on understanding of the gaps in the process and tools. Our interview process is designed to give you every chance to get the measure of us, and us of you. You will join three stages which will give you every opportunity to show your strengths and qualities, via scenario based questions and technical exercises. Competitive salary benchmarked against the market Participation in a great company equity scheme Enhanced pension contributions Annual holiday allowance of 25 days per year Overseas working policy for up to 8 weeks per year Flexible, hybrid and remote working arrangements Comprehensive Private Health cover with the option to add family members, Enhanced health and wellbeing benefits including health cash plan, critical illness cover, life assurance and group income protection Enhanced paid maternity and paternity policy If you're excited by deep technical problems, real-world AI, and the opportunity to build technology that will reshape global industry, you'll find both the challenge and the impact you're looking for at Oxa. #J-18808-Ljbffr

We are looking for a highly technical Senior Software Engineer to join our System Orchestration team in System Software at Oxford Ionics. In this role, you will be responsible for building and operating the software that keeps our systems calibrated, decides what they do next and keeps the record of what they did, contributing to the team's mission of keeping our quantum computers running useful work around the clock. The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune - settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output. Calibration routines, scientists' experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec - on a machine still hitting the fidelity it is meant to hit. The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned. You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them. This is a hands‑on engineering role and stays that way as you grow in it. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required., This is a hands‑on engineering role, balancing delivery of your own areas with support for the teams and scientists who depend on them., • Own a group of device controllers end to end, covering API design, implementation, rollout and ongoing operational health., • Make services robust against the ways real instruments fail., • Bring devices onto our current framework, and roll the result out across the fleet without disrupting running experiments., • Improve the shared framework where a problem turns out to be common to many controllers rather than specific to one., • Work closely with the systems teams and scientists who depend on these services, and strengthen observability, health checking and alerting., • Raise the standard of the code around you through review, and bring less experienced engineers on by working alongside them. To be successful, you will need experience building stateful services that stay correct under failure, and a track record of changing a load‑bearing system while people depend on it. We're looking for someone who can own a problem area with little supervision and contribute effectively within a fast moving, highly technical team., Strong systems engineering skills. Our System Orchestration layer is written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming. • Experience designing and operating networked services (such as gRPC or REST), with a real grasp of error handling, observability and failure modes., • Real experience with a relational database as a source of truth - schema design, migrations against live data, and transactions. We use PostgreSQL., • A track record of getting lifecycle and concurrency right: state machines, timeouts, leases, retries, and the failure modes that only show up under load., • Experience with a scheduler, workflow engine or job queue - Temporal, Airflow, Celery, Slurm, or one you built - or with event‑driven systems that react to changes in state., • A habit of settling design questions in writing, with options weighed as peers., • Comfort owning the production behaviour of what you build, not just its correctness in test., • Excellent communication skills both within software and across disciplines., • An interest in helping other engineers get better at the craft, without wanting to stop building yourself. Additional useful experience would include running containerised services in production, Kubernetes, distributed tracing, closed‑loop systems that act on measured state, and scientific computing or research facilities.

Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. Location: Oxford, UK Office commitment: Hybrid The Role: Quantum is now, and it's built here. Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world‑leading trapped‑ion technology, we're building the most powerful, accurate and reliable quantum systems to tackle problems that today's supercomputers cannot solve. We're looking for an enthusiastic and highly technical Staff Software Engineer for our non‑realtime controllers team who will thrive in our dynamic cross‑disciplinary environment. You'd be working closely with our skilled software engineers, our systems teams who operate the physical quantum computers, and our world‑leading quantum scientists to build and operate the software that controls the hardware surrounding our quantum computers. Previous exposure to quantum systems is not required. You will take on our most demanding hardware integrations and the framework work that makes every other controller better. This is a hands‑on engineering role: you would be the most experienced engineer writing controllers, not the one directing others to write them. A working quantum computer is far more than the ion trap and its real‑time control electronics. It depends on a fleet of supporting hardware, including cryogenic compressors, vacuum pumps, power supplies, lasers, temperature controllers, wavemeters and cameras, that has to be kept observable, controllable and reliable. The timing‑critical operations such as gate waveforms and ion transport run on dedicated real‑time FPGA systems, while this team owns everything that does not need hard timing guarantees. These services run on general‑purpose Linux hardware and must be rock‑solid, because a failed compressor or an un‑noticed pressure drift takes a whole machine offline. Responsibilities: This is a hands‑on engineering role. Your influence comes from the code you ship and review, and from the problems you take off everyone other's plate. Key responsibilities include: • Take on our most demanding device integrations, and do the deep diagnosis of problems that only appear against real hardware in a live lab., • Remove whole classes of failure across the fleet, rather than instances of them., • Improve the shared framework yourself, and bring the existing controllers along with each change., • Build the tooling, simulators and test infrastructure that let the whole team move faster., • Evolve how our services are deployed and operated as the fleet grows, and make the fleet observable enough that problems are found early., • Raise the bar of everyone around you through the code you write and the reviews you give. Requirements: To be successful, you will need deep systems engineering experience, a track record of shipping and operating reliable services, and the judgement to tell a problem worth solving structurally from one worth patching. We're looking for someone who wants to stay hands‑on in the code at this level rather than move away from it. You’ll be a great fit with: • Expert systems engineering skills. Our controllers are written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming., • Experience building and operating networked services in production such as gRPC or REST, with a real grasp of error handling, observability and failure modes., • Experience of hardware and instrument protocols and interfaces such as SCPI, Modbus, serial and Ethernet., • A reputation as the person people bring the undiagnosable bug to, and the ability to prioritise work with a clear understanding of critical versus urgent items., • Excellent communication skills both within software and across disciplines. Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing. We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with IonQ stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more. Join us and be part of the future of quantum computing. We’re proud to be an equal opportunity employer and welcome applicants from all backgrounds. Compensation will vary based on individual factors such as education, qualifications, and experience of the final candidate(s), specific office location, and calibration against relevant market data and internal team equity. Posted base salary figures are subject to change as new market data becomes available. Our benefits include comprehensive medical, dental, and vision plans, matching 401(k), unlimited PTO and paid holidays, parental/adoption leave, legal insurance, and a home technology stipend. Details of participation in these benefit plans will be provided when a candidate receives an offer of employment. At IonQ, we believe in fair treatment, access, opportunity, and advancement for all while striving to identify and eliminate barriers.

Oxa’s customers are the operators of some of the world's largest industrial facilities. Our technology transforms existing industrial vehicles into intelligent autonomous fleets, unlocking new levels of productivity, safety, and performance. ‘The phone in your hand, the coffee on your desk, the shirt on your back - they all moved through a web of ports (air and sea), distribution yards and manufacturing hubs. This is the invisible circulatory system of global trade, and it relies entirely on a relentless, repetitive shuffle of goods. Towing. This towing task happens in complex, commerce-critical industrial environments. Here, having self driving technology “do the driving” delivers immediate, measurable impact. IMA will revolutionise the movement of goods across the world's ports, airports, and yards. You can be part of that as an Oxbot’ ‘Paul Newman - Founder and CEO’ Our products are built on four core technology pillars which come together to build a complete system: Oxa Ware – Our modular autonomy hardware systems for consistent and repeatable integration of autonomy with existing vehicles. Oxa Driver – Our Physical AI, embodied in Oxa Ware, self-driving software that enables vehicles to perceive, reason, and drive autonomously in complex real-world environments. Oxa Foundry – Our development toolchain that leverages generative AI to continuously train and assure Oxa Driver, synthesising situations and sensor data. Oxa Hub – Our suite of cloud services for monitoring, managing and orchestrating fleets driven by Oxa Driver, including an API for integration with existing logistics systems. Behind these technologies is our exceptional team, the Oxbots. We are home to some of the world's leading experts in autonomous systems, robotics, machine learning, artificial intelligence, cloud infrastructure, and distributed software engineering. Together, we're solving some of the hardest technical challenges in autonomy, turning the research and development we do into production and deploying it into environments. Making robots do useful work. You’ll join the Over-the-Air and Configuration (OTAC) team, which gets software and configuration efficiently from our cloud onto every vehicle in the fleet. Every release of Oxa Driver, and every configuration change behind it, reaches a vehicle through systems this team builds and runs. This is a full-stack role with its centre of gravity in the back end and on Linux. Most of the hard problems here aren't in the UI: they're in making distributed systems talk to each other reliably. Think vehicles on complex networks, reliable updates that must never leave a vehicle half-installed, state that has to stay in sync between cloud and edge, and security that holds up end to end between Oxa infrastructure and vehicles operating in the field. We use AI tooling heavily, so the front-end work moves fast. What we need most is an engineer who wants to understand how the whole system works, from the GCP services and APIs down to the Linux stack running on the vehicle. OTA and configuration platform: design, build and run the back-end services, primarily in Python, that deliver software and configuration to our vehicle fleet. Cloud-to-vehicle systems: solve the hard integration problems between cloud and edge, including syncing, timing, intermittent connectivity and safe rollback. Linux and on-vehicle software: work close to the Linux stack on our vehicles, understanding how updates land, how services behave and how to diagnose them when they don't. Infrastructure and deployment: own cloud infrastructure on GCP and fleet deployment tooling built on Terraform and Mender, with robust CI/CD behind it. Security: help ensure every update is authenticated, auditable and resilient, as the fleet scales across customer sites. Full-stack delivery: build the APIs and web tools that operators and engineers use to manage releases, using AI-assisted development to move quickly on the front end. Technical leadership: shape the team's technical strategy, spot gaps early and drive engineering best practice across OTAC. Mentorship: support and grow the engineers around you and raise the bar for the whole team. A track record of solving genuinely difficult engineering problems, and the ability to explain how you approached them. Strong back-end engineering skills, with deep expertise in Python and in designing ergonomic APIs and scalable services. Solid Linux and systems knowledge: you’re comfortable below the application layer, with networking, processes, packaging and debugging. Experience with distributed systems where components must stay in sync, such as complex apps with real timing or consistency problems between client and server. Hands‑on experience with cloud infrastructure (ideally GCP), infrastructure as code (ideally Terraform) and modern CI/CD. Enough full‑stack ability to build and ship the web tools around your services, and comfort using agentic tools such as Claude Code or Gemini to do it. Clear communication: you can turn complex technical risk into precise guidance for leadership and peers. We care more about how you think than where you started. Good engineering thinking shows up in many fields, and we’re open to people from all of them. An undergraduate degree (BEng/MEng/MSc) is welcome and equivalent professional experience also counts. Experience with OTA update systems (such as Mender), embedded Linux or device fleet management. Experience working alongside robotics, autonomy or other complex hardware‑driven systems. Security experience, such as secure software delivery, incident response or recovery work. Experience leading technical decisions. Experience with large migrations or data pipelines where correctness really mattered. Familiarity with TypeScript, Node.js and React, or with real‑time dashboards and monitoring tools. A curiosity that shows outside work: a home lab, self‑hosted services, robotics projects or anything else where you've taken a system apart to see how it works Our interview process is designed to give you every chance to get the measure of us, and us of you. You will join three stages which will give you every opportunity to show your strengths and qualities, via scenario based questions and technical exercises. Competitive salary benchmarked against the market Participation in a great company equity scheme Enhanced pension contributions Annual holiday allowance of 25 days per year Overseas working policy for up to 8 weeks per year Flexible, hybrid and remote working arrangements Comprehensive Private Health cover with the option to add family members, Enhanced health and wellbeing benefits including health cash plan, critical illness cover, life assurance and group income protection Enhanced paid maternity and paternity policy If you're excited by deep technical problems, real-world AI, and the opportunity to build technology that will reshape global industry, you'll find both the challenge and the impact you're looking for at Oxa. #J-18808-Ljbffr

IonQ is making quantum platforms more accessible and impactful than ever before. Location: Oxford, UK Office commitment: Hybrid We are looking for an enthusiastic Software Engineer to join our System Orchestration team in System Software at Oxford Ionics. In this role, you will be responsible for building the software that keeps our systems calibrated, decides what they do next and keeps the record of what they did, contributing to the team’s mission of keeping our quantum computers running useful work around the clock. The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune – settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output. Calibration routines, scientists’ experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec – on a machine still hitting the fidelity it is meant to hit. The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned. You’d work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them. You will own features end to end, from the API through to the rollout onto real machines. You’ll play an important part in shaping the services that support our work in building the world’s most advanced quantum systems. Previous exposure to quantum systems is not required. In this position, you will work on the services that schedule work onto our quantum computers and keep the record of it, supporting the effective delivery of a control plane the whole fleet depends on. You’ll have the opportunity to own real pieces of that system end to end, contributing directly to the success of the System Software function. Key responsibilities include: • Build and extend the services that schedule work on our systems and keep the record of it., • Build the mechanisms that decide when a system needs re-tuning, and get those calibrations run., • Own what we persist: the data model, its migrations, and the code that reads and writes it., • Produce the tests and harnesses that let our code be exercised against real hardware and against simulators., • Work with the systems teams to roll releases out across the fleet and support them once they are running., • Improve the observability of the code you ship., • Take part in code review, and improve the APIs our internal users depend on To be successful, you will need solid programming skills, an interest in the systems that keep long-running machines working, and either experience of a systems programming language or the appetite to learn one. We’re looking for someone who can work comfortably in a Linux environment, cares about what happens to data when a service crashes or a migration goes wrong, and can contribute effectively within a fast moving, highly technical team. Strong programming skills in one or more mainstream programming languages. Experience with a systems programming language. Our System Orchestration layer is written in Rust, so either some Rust experience or the appetite to learn it. Comfort with relational databases and SQL; we use PostgreSQL. Some exposure to networked services and APIs, such as gRPC or REST. Exposure to schedulers, job queues or workflow engines – Celery, Airflow, Temporal, Slurm or similar. Comfort working on Linux, and debugging a service that is already running. Good communication skills both within software and across disciplines. A habit of producing appropriate tests and taking part in code review. Additional useful experience would include async programming, containers and Kubernetes, closed-loop systems that act on measured state, and scientific computing or research facilities. Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing.

The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune - settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output. Calibration routines, scientists' experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec - on a machine still hitting the fidelity it is meant to hit. The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned. You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them. This is a hands-on engineering role: you would be writing this software alongside our other staff engineers, not directing others who write it. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required. In this position, you will work across the services that make up the control plane, supporting the effective delivery of a system every machine in the fleet depends on. You'll have the opportunity to remove whole classes of failure and raise the bar for the engineers around you, contributing directly to the success of the System Software function. Key responsibilities include: • Take on the problems that span the whole control plane - the durability and recovery contracts the rest of the design rests on., • Make a machine's own assessment of its readiness something the rest of the control plane can rely on.Do the deep diagnosis of failures that only appear on a live system, under real load., • Remove whole classes of failure across the fleet, rather than instances of them., • Draw the boundaries between our services, settle them in writing, and move the code across them yourself., • Make the correctness of a design demonstrable rather than argued., • Build the tooling and test infrastructure that let the whole team move faster., • Evolve how our services are deployed and operated as the fleet grows., • Raise the bar of everyone around you through the code you write and the reviews you give. To be successful, you will need deep systems engineering experience, a track record of operating services where losing data is not an option, and the judgement to tell a problem worth solving structurally from one worth patching. We're looking for someone who wants to stay hands-on in the code at this level and can contribute effectively within a fast moving, highly technical team. You'd be a great fit with: • Expert systems engineering skills. Our System Orchestration layer is written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming., • Deep experience building and operating stateful networked services in production, exposed over gRPC or REST, with a real grasp of error handling, observability and failure modes., • A track record with data durability and correctness - persistence design, crash recovery, and migrations against live data you cannot afford to lose. We use PostgreSQL., • The instinct to reach for determinism when chasing a timing or interleaving bug, rather than for more logging., • Depth in the scheduling and workflow landscape - Temporal, Hatchet, Airflow, Slurm, Postgres-backed queues - and the judgement to borrow from it rather than reinvent., • A track record of pinning down failures that others could not., • A habit of settling design questions in writing, with the options compared as peers., • Excellent communication skills both within software and across disciplines. Additional useful experience would include replacing a load-bearing system while it stays in service, containerised services in production, Kubernetes and declarative deployment, distributed tracing, formal specification or model checking, closed-loop systems that act on measured state, and scientific computing or research facilities. Be part of a team that's shaping the future of quantum. We offer more than just a role, you'll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing. We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with IonQ stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more.

IonQ is making quantum platforms more accessible and impactful than ever before. Oxford, England, UK Hybrid We are looking for a Staff Platform Engineer to join the Quantum System Infrastructure team at IonQ, based in our Oxford office. In this role, you will be responsible for the platform that our engineering and science teams use to build, test and deliver quantum systems to customers, contributing to the team's mission of applying DevSecOps principles to deliver reliable, secure and observable infrastructure, on‑site and in the cloud. As a Staff Engineer you will play a leading role in shaping the clusters, pipelines, monitoring and remote development environments that support our work in building the world's most advanced quantum systems. You'll have the opportunity to drive meaningful work in a unique environment, operating alongside the physicists and engineers who build those systems, and see vacuum chambers, cryostats and lasers in action on site. In this position, you will build and run the infrastructure behind our quantum systems, on‑site and in the cloud, so the teams who build them can ship changes quickly and safely. You'll have the opportunity to shorten the time from a code change to a running quantum system, contributing directly to the delivery of quantum systems to our customers. As a senior member of the team, you will take on central roles in strategic projects for the Platform team, and will lead on defining, driving and implementing them. You'll work with a wide range of partners and internal customers across IonQ's locations: physicists, lab technicians, firmware and software engineers, IT, product management and production SRE. You'll talk to them, see where they get stuck and fix the cause. Key responsibilities include: • Run and evolve the Kubernetes platform behind each quantum system, and the release process that promotes software onto it (k3s, ArgoCD, Helm), • Make CI faster and more reliable for every engineer, including our scarce hardware‑in‑the‑loop and FPGA build runners and build caches (GitHub Actions), • Make our systems observable: define dashboards and alerts as code for quantum system hardware such as lasers, cryogenics and vacuum, and move them onto IonQ's shared observability platform with our production Site Reliability Engineering (SRE) colleagues (Grafana, OpenTelemetry), • Give every engineer and physicist a ready‑to‑use remote development environment, on‑site or in the cloud, that works with our quantum system hardware, • Keep our on‑site and cloud infrastructure secure, recoverable, reproducible and reviewable as code (OpenTofu, Atmos), from secrets and access to certificates and identity, and work with IonQ's infrastructure team on shared cloud services, • Lead technical decisions and write the runbooks and guides that let other teams change the platform safely themselves To be successful, you will need hands‑on experience running Linux infrastructure in production, ideally both on‑premises and in the cloud, with infrastructure as code, Kubernetes and CI/CD. We're looking for someone who can diagnose problems across the whole stack, from a storage fault to a failing pipeline to a development environment that will not start, who treats observability and security as part of the job rather than an afterthought, and who can lead a piece of work from design to rollout within a fast‑moving, highly technical team. You will write mostly Python, shell and OpenTofu. Our product code is Rust and Python: your job will be to make it build and test faster rather than write it. Our platform spans our on‑site quantum systems, and many changes reach live quantum systems. Every change goes through review and automated validation before it is applied, so we value people who plan for rollback, test against the real system and write down what they learn. Experience with AI coding tools is helpful, as is an interest in quantum computing though prior experience is not required. You’d be a great fit with: • 5+ years in a Platform, DevOps or Site Reliability role, running Linux systems in production, • Infrastructure as code with Terraform or OpenTofu, • Running containerised workloads on Kubernetes in production, • Building and speeding up CI/CD pipelines, ideally in GitHub Actions, • Observability and security for production systems: monitoring, alerting, secrets and access control Be part of a team that’s shaping the future of quantum.

Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. System Software builds the software that runs IonQ's quantum computers: the runtime, orchestration, quantum tools, controllers and transport software that sit between the Quantum Operating System and the hardware. It is where a next-generation system either comes together or doesn't. We're hiring a Staff Technical Programme Manager to lead delivery across this stack. You'll report to the Group Program Manager, Software in our Programme Management Office and be matrixed to the VP, Software for day-to-day work. You’ll work across five engineering teams (runtime, orchestration, quantum tools, controllers and transport) and the interfaces between them and their cross-functional stakeholders, serving several next-generation system programmes at once, with hardware being co-developed alongside the software and teams in both Oxford and the US. Those programmes draw on the same engineers, so the central problem of this role is making sure that capacity is spent by decision, not by default. We run a centralised PMO model. This role will not own engineering headcount or define product but it will make the programme around those things run. It carries real ownership of delivery: the plan, the trade-offs put in front of decision-makers, and the honesty of the status. In this role you will interface with everyone from technical software engineers to a wide range of the most senior stakeholders. You will also coordinate with your fellow programme managers, across Science, Infrastructure and broader Software teams, making sure all plans are shared and coordinated, rather than operating in silos. Turning a research-grade quantum system into a dependable product is a problem nobody has finished solving, and the delivery standard you'll work within is being built now. If writing the first version of the plan sounds like the interesting part, we should talk. In this role you will own the end-to-end delivery of the Systems Software roadmap across several concurrent programmes including managing dependencies between hardware, science and systems integration teams. You will partner closely with engineering leadership, the engineering teams run the day to day planning and boards, you will provide the direction that creates incremental milestones that ship. You will identify risks and blockers early and work with the teams to resolve them. You will also run intake and triage, so requests reach the right team with the right priority and engineers can stay focused on planned work. Key responsibilities include: • Make contention visible: when two programmes need the same team in the same quarter, bring it to the right decision-maker with the options and a recommendation before it becomes a slip., • Keep the systems of record honest. Requirements, plans, schedules and Jira drift apart; you'll close the gap and automate the checking., • Make invisible work visible: on-call load, sustaining work and technical debt tracked as rigorously as feature delivery., • Surface risks early, before you have a full solution or complete alignment. We'd rather hear it messy and on time., • Run intake and triage so requests reach the right team, with priority set by the people who own it, and engineers stay on planned work., • Work hand in hand with the Quantum Systems Infrastructure and Science TPMs in Oxford and the Software TPMs in the US: shared processes where teams meet, and no duplicated ceremonies, boards or reports., • Write concise, plain-English status on progress, risks and decisions for programme directors, engineering leaders and senior leadership., • Help shape how IonQ runs software delivery across sites, working with the Group Program Manager, Software on the shared delivery standard. You will have significant experience running technical programmes across several software teams, ideally in systems, embedded, compiler or platform software. You can discuss scope and trade-offs directly with engineering leads, read and reason about code, and re-plan when a timeline is no longer realistic. You will have a track record of leading teams through genuine ambiguity, writing the first version of the plan when there isn't one, not just executing a defined one. You can break broad problems down into specific, assignable actions, and you have designed a team's operating cadence before. No quantum background is needed. Experience of software that works closely with hardware, for example in labs, robotics, aerospace or scientific instruments, would be beneficial. You'd be a great fit with: • A habit of turning diffuse problems into specific, minimal, assignable asks., • Technical fluency to engage engineering leads directly on scope and trade-offs, and comfort reading and reasoning about code., • Willingness to re-baseline against reality rather than defend dates that have stopped being true, and the judgement to tell a target that motivates from one that just generates fiction., • Experience with software that works closely with hardware: labs, robotics, aerospace, scientific instruments or similar., • A chase-without-nagging, elevate-without-drama style, and a clear sense of the difference between a risk and a noise., • AI as a core part of how you work, for example agent-driven tracking, reconciliation or reporting., • Clear, concise written and verbal communication with both technical and senior stakeholders. Additional desirable skills include capacity and staffing modelling, designing operating cadences and experience leading work across sites and time zones. Experience working with programmes and systems such as Jira, Confluence and GitHub, with a preference for lightweight processes, is also helpful.

We are looking for a highly technical Senior Software Engineer to join our System Orchestration team in System Software at Oxford Ionics. In this role, you will be responsible for building and operating the software that keeps our systems calibrated, decides what they do next and keeps the record of what they did, contributing to the team's mission of keeping our quantum computers running useful work around the clock. The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune - settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output. Calibration routines, scientists' experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec - on a machine still hitting the fidelity it is meant to hit. The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned. You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them. This is a hands‑on engineering role and stays that way as you grow in it. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required., This is a hands‑on engineering role, balancing delivery of your own areas with support for the teams and scientists who depend on them., • Own a group of device controllers end to end, covering API design, implementation, rollout and ongoing operational health., • Make services robust against the ways real instruments fail., • Bring devices onto our current framework, and roll the result out across the fleet without disrupting running experiments., • Improve the shared framework where a problem turns out to be common to many controllers rather than specific to one., • Work closely with the systems teams and scientists who depend on these services, and strengthen observability, health checking and alerting., • Raise the standard of the code around you through review, and bring less experienced engineers on by working alongside them. To be successful, you will need experience building stateful services that stay correct under failure, and a track record of changing a load‑bearing system while people depend on it. We're looking for someone who can own a problem area with little supervision and contribute effectively within a fast moving, highly technical team., Strong systems engineering skills. Our System Orchestration layer is written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming. • Experience designing and operating networked services (such as gRPC or REST), with a real grasp of error handling, observability and failure modes., • Real experience with a relational database as a source of truth - schema design, migrations against live data, and transactions.

Headquartered in College Park, Maryland, IonQ has operations in California, Colorado, Massachusetts, Tennessee, Washington, Italy, South Korea, Sweden, Switzerland, Canada, and the United Kingdom. Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. We are looking for a HIL (hardware-in-the-loop) Test Manager to build and lead the team that owns our hardware test infrastructure: the systems our quantum‑computer control software is tested on before it ever touches a real quantum system. Every software and science change is validated against shared test systems before it reaches a quantum computer. We are now investing in the next generation of these: representative QA systems for fast feedback, and staging systems as close to a production quantum system as possible, with all the real‑time and non‑real‑time hardware. You will define these systems, build them with our manufacturing team, and own them through their life: maintenance, upgrades to each programme baseline, and availability to the teams that depend on them. This is a build‑from‑scratch role with budget and rack space already allocated. You will also act as our test architect: we have deep physics and engineering expertise, and you will bring the formal software‑testing experience to shape what gets tested where (simulation versus real hardware) and how testing gates releases. You will start with one engineer hire alongside you and grow the team deliberately, turning the test estate into a reliable service the engineering teams depend on. You will own the hardware test estate end to end and define how it is used. That includes making the estate self‑service, with clear reservation and scheduling, published state and availability, and runbooks. Teams own their tests and what they gate on; your team owns the rigs and the plumbing. You will hire, develop and lead a small team, starting with a hardware‑focused test systems engineer, and work across the business with the wider Quantum System Infrastructure (QSI) teams, Compute IT, Facilities, Manufacturing, Software and Science. • Own the hardware test estate: today's CI systems through to the new QA and staging systems for our current and future quantum‑computer programmes., • Define the test‑system architecture: which systems exist, what each one represents, and how teams use them., • Plan and deliver new test-system builds with Manufacturing, and own ongoing maintenance and upgrades so every test system tracks its programme's current baseline., • Shape the testing strategy with the software teams: what runs in simulation or against emulators, what requires real hardware, and how hardware‑in‑the-loop results gate releases., • Drive automation throughout: provisioning, firmware flashing, recovery and configuration of test systems as code, not manual effort. We are looking for an experienced test leader who can bring structure, ownership and pace to how we validate software against real hardware. We treat QA and test as one discipline. You will have a working knowledge of modern CI/CD (GitHub Actions or comparable) and an automation‑first instinct: repeatable and reliable over manual and heroic. You will be able to guide and review test‑automation development in Python or similar; you direct the code, you do not have to be its main author. These systems serve many teams, so strong collaboration and low ego matter: you will need to bring people with you as ownership and ways of working evolve. You will be comfortable with ambiguity and building from scratch in a fast‑moving technical environment. Experience in quantum computing is not required. Experience with complex hardware and software systems or similarly demanding engineering environments is an advantage. • A strong software testing and QA background covering test strategy, test infrastructure and continuous integration. This is the core requirement., • Experience owning test infrastructure where software is validated against real hardware, for example network and security appliances, autonomous vehicles, drones or defence systems, robotics, or other embedded products., • Test‑architecture capability: designing representative test environments, deciding what to test where, and balancing simulation against hardware‑in‑the‑loop., • Practical understanding of the pitfalls of testing with hardware in the loop, such as flaky devices, contention for rigs and environment drift. Deep hands‑on electronics skills are not required., • Experience leading or building a small testing team or function. Compensation will vary based on individual factors such as education, qualifications, and experience of the final candidate(s), specific office location, and calibration against relevant market data and internal team equity. Posted base salary figures are subject to change as new market data becomes available. Our benefits include comprehensive medical, dental, and vision plans, matching 401(k), unlimited PTO and paid holidays, parental/adoption leave, legal insurance, and a home technology stipend. Details of participation in these benefit plans will be provided when a candidate receives an offer of employment. At IonQ, we believe in fair treatment, access, opportunity, and advancement for all while striving to identify and eliminate barriers.

Headquartered in College Park, Maryland, IonQ has operations in California, Colorado, Massachusetts, Tennessee, Washington, Italy, South Korea, Sweden, Switzerland, Canada, and the United Kingdom. Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. System Software builds the software that runs IonQ's quantum computers: the runtime, orchestration, quantum tools, controllers and transport software that sit between the Quantum Operating System and the hardware. It is where a next-generation system either comes together or doesn't. We're hiring a Staff Technical Programme Manager to lead delivery across this stack. You'll report to the Group Program Manager, Software in our Programme Management Office and be matrixed to the VP, Software for day-to-day work. You'll work across five engineering teams (runtime, orchestration, quantum tools, controllers and transport) and the interfaces between them and their cross-functional stakeholders, serving several next-generation system programmes at once, with hardware being co-developed alongside the software and teams in both Oxford and the US. Those programmes draw on the same engineers, so the central problem of this role is making sure that capacity is spent by decision, not by default. We run a centralised PMO model. This role will not own engineering headcount or define product but it will make the programme around those things run. It carries real ownership of delivery: the plan, the trade-offs put in front of decision-makers, and the honesty of the status. In this role you will interface with everyone from technical software engineers to a wide range of the most senior stakeholders. You will also coordinate with your fellow programme managers, across Science, Infrastructure and broader Software teams, making sure all plans are shared and coordinated, rather than operating in silos. Turning a research-grade quantum system into a dependable product is a problem nobody has finished solving, and the delivery standard you'll work within is being built now. If writing the first version of the plan sounds like the interesting part, we should talk. In this role you will own the end-to-end delivery of the Systems Software roadmap across several concurrent programmes including managing dependencies between hardware, science and systems integration teams. You will partner closely with engineering leadership, the engineering teams run the day to day planning and boards, you will provide the direction that creates incremental milestones that ship. You will identify risks and blockers early and work with the teams to resolve them. You will also run intake and triage, so requests reach the right team with the right priority and engineers can stay focused on planned work. Key responsibilities include: • Make contention visible: when two programmes need the same team in the same quarter, bring it to the right decision-maker with the options and a recommendation before it becomes a slip., • Keep the systems of record honest. Requirements, plans, schedules and Jira drift apart; you'll close the gap and automate the checking., • Make invisible work visible: on-call load, sustaining work and technical debt tracked as rigorously as feature delivery., • Surface risks early, before you have a full solution or complete alignment. We'd rather hear it messy and on time., • Run intake and triage so requests reach the right team, with priority set by the people who own it, and engineers stay on planned work., • Work hand in hand with the Quantum Systems Infrastructure and Science TPMs in Oxford and the Software TPMs in the US: shared processes where teams meet, and no duplicated ceremonies, boards or reports., • Write concise, plain-English status on progress, risks and decisions for programme directors, engineering leaders and senior leadership., • Help shape how IonQ runs software delivery across sites, working with the Group Program Manager, Software on the shared delivery standard. You will have significant experience running technical programmes across several software teams, ideally in systems, embedded, compiler or platform software. You can discuss scope and trade-offs directly with engineering leads, read and reason about code, and re-plan when a timeline is no longer realistic. You will have a track record of leading teams through genuine ambiguity, writing the first version of the plan when there isn't one, not just executing a defined one. You can break broad problems down into specific, assignable actions, and you have designed a team's operating cadence before. No quantum background is needed. Experience of software that works closely with hardware, for example in labs, robotics, aerospace or scientific instruments, would be beneficial. • A habit of turning diffuse problems into specific, minimal, assignable asks., • Technical fluency to engage engineering leads directly on scope and trade-offs, and comfort reading and reasoning about code., • Willingness to re-baseline against reality rather than defend dates that have stopped being true, and the judgement to tell a target that motivates from one that just generates fiction., • Experience with software that works closely with hardware: labs, robotics, aerospace, scientific instruments or similar., • A chase-without-nagging, elevate-without-drama style, and a clear sense of the difference between a risk and a noise., • AI as a core part of how you work, for example agent-driven tracking, reconciliation or reporting., • Clear, concise written and verbal communication with both technical and senior stakeholders. Additional desirable skills include capacity and staffing modelling, designing operating cadences and experience leading work across sites and time zones. Experience working with programmes and systems such as Jira, Confluence and GitHub, with a preference for lightweight processes, is also helpful. Compensation will vary based on individual factors such as education, qualifications, and experience of the final candidate(s), specific office location, and calibration against relevant market data and internal team equity.

IonQ’s newest generation of quantum computers, the IonQ Tempo, is the latest in a line of cutting-edge systems that have been helping customers and partners including Amazon Web Services, and AstraZeneca achieve 20x performance results and accelerate innovation in drug discovery, materials science, financial modeling, logistics, cybersecurity, and defense. In 2025, the company achieved 99.99% two-qubit gate fidelity, setting a world record in quantum computing performance. Headquartered in College Park, Maryland, IonQ has operations in California, Colorado, Massachusetts, Tennessee, Washington, Italy, South Korea, Sweden, Switzerland, Canada, and the United Kingdom. Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. Oxford, UK Hybrid We are looking for a highly technical Staff Software Engineer to join our System Orchestration team in System Software at Oxford Ionics. In this role, you will be responsible for building and operating the software that keeps our systems calibrated, decides what they do next and keeps the record of what they did, contributing to the team's mission of keeping our quantum computers running useful work around the clock. The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune - settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output. Calibration routines, scientists' experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec - on a machine still hitting the fidelity it is meant to hit. The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned. You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them. This is a hands‑on engineering role: you would be writing this software alongside our other staff engineers, not directing others who write it. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required. In this position, you will work across the services that make up the control plane, supporting the effective delivery of a system every machine in the fleet depends on. You'll have the opportunity to remove whole classes of failure and raise the bar for the engineers around you, contributing directly to the success of the System Software function. Key responsibilities include: • Take on the problems that span the whole control plane - the durability and recovery contracts the rest of the design rests on., • Make a machine's own assessment of its readiness something the rest of the control plane can rely on.Do the deep diagnosis of failures that only appear on a live system, under real load., • Remove whole classes of failure across the fleet, rather than instances of them., • Draw the boundaries between our services, settle them in writing, and move the code across them yourself., • Make the correctness of a design demonstrable rather than argued., • Build the tooling and test infrastructure that let the whole team move faster., • Evolve how our services are deployed and operated as the fleet grows., • Raise the bar of everyone around you through the code you write and the reviews you give. To be successful, you will need deep systems engineering experience, a track record of operating services where losing data is not an option, and the judgement to tell a problem worth solving structurally from one worth patching. We're looking for someone who wants to stay hands‑on in the code at this level and can contribute effectively within a fast moving, highly technical team. You'd be a great fit with: • Expert systems engineering skills. Our System Orchestration layer is written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming., • Deep experience building and operating stateful networked services in production, exposed over gRPC or REST, with a real grasp of error handling, observability and failure modes., • A track record with data durability and correctness - persistence design, crash recovery, and migrations against live data you cannot afford to lose. We use PostgreSQL., • The instinct to reach for determinism when chasing a timing or interleaving bug, rather than for more logging., • Depth in the scheduling and workflow landscape - Temporal, Hatchet, Airflow, Slurm, Postgres-backed queues - and the judgement to borrow from it rather than reinvent., • A track record of pinning down failures that others could not., • A habit of settling design questions in writing, with the options compared as peers., • Excellent communication skills both within software and across disciplines. Additional useful experience would include replacing a load-bearing system while it stays in service, containerised services in production, Kubernetes and declarative deployment, distributed tracing, formal specification or model checking, closed-loop systems that act on measured state, and scientific computing or research facilities.

Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world‑leading trapped‑ion technology, we're building the most powerful, accurate and reliable quantum systems to tackle problems that today's supercomputers cannot solve. We're looking for an enthusiastic and highly technical Staff Software Engineer for our non‑realtime controllers team who will thrive in our dynamic cross‑disciplinary environment. You'd be working closely with our skilled software engineers, our systems teams who operate the physical quantum computers, and our world‑leading quantum scientists to build and operate the software that controls the hardware surrounding our quantum computers. Previous exposure to quantum systems is not required. You will take on our most demanding hardware integrations and the framework work that makes every other controller better. This is a hands‑on engineering role: you would be the most experienced engineer writing controllers, not the one directing others to write them. A working quantum computer is far more than the ion trap and its real‑time control electronics. It depends on a fleet of supporting hardware, including cryogenic compressors, vacuum pumps, power supplies, lasers, temperature controllers, wavemeters and cameras, that has to be kept observable, controllable and reliable. The timing‑critical operations such as gate waveforms and ion transport run on dedicated real‑time FPGA systems, while this team owns everything that does not need hard timing guarantees. These services run on general‑purpose Linux hardware and must be rock‑solid, because a failed compressor or an un‑noticed pressure drift takes a whole machine offline. This is a hands‑on engineering role. Your influence comes from the code you ship and review, and from the problems you take off everyone other's plate. • Take on our most demanding device integrations, and do the deep diagnosis of problems that only appear against real hardware in a live lab., • Remove whole classes of failure across the fleet, rather than instances of them., • Improve the shared framework yourself, and bring the existing controllers along with each change., • Build the tooling, simulators and test infrastructure that let the whole team move faster., • Evolve how our services are deployed and operated as the fleet grows, and make the fleet observable enough that problems are found early., • Raise the bar of everyone around you through the code you write and the reviews you give. To be successful, you will need deep systems engineering experience, a track record of shipping and operating reliable services, and the judgement to tell a problem worth solving structurally from one worth patching.

IonQ is making quantum platforms more accessible and impactful than ever before. Oxford, UK Hybrid We are looking for a highly technical Senior Software Engineer to join our System Orchestration team in System Software at Oxford Ionics. In this role, you will be responsible for building and operating the software that keeps our systems calibrated, decides what they do next and keeps the record of what they did, contributing to the team's mission of keeping our quantum computers running useful work around the clock. The trapped-ion quantum computers we are building will control 10,000 ions within two years, and all of that has to be kept in tune - settings that drift over minutes, hours and days. Without it a computer does not stop; it quietly starts producing invalid output. Calibration routines, scientists' experiments and customer workloads all compete for physical hardware, and our team builds the control plane that arbitrates that: it schedules and prioritises programs, hands exclusive access to one at a time and takes it back cooperatively, streams results while a program is still running, and keeps the record of everything that ran. It runs on every quantum computer in our fleet. Its job is to keep that machine busy and productive: running quantum programs rather than waiting in between, and running them in spec - on a machine still hitting the fidelity it is meant to hit. The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned. You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them. This is a hands-on engineering role and stays that way as you grow in it. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required. This is a hands-on engineering role, balancing delivery of your own areas with support for the teams and scientists who depend on them. Key responsibilities include: • Own a group of device controllers end to end, covering API design, implementation, rollout and ongoing operational health., • Make services robust against the ways real instruments fail., • Bring devices onto our current framework, and roll the result out across the fleet without disrupting running experiments., • Improve the shared framework where a problem turns out to be common to many controllers rather than specific to one., • Work closely with the systems teams and scientists who depend on these services, and strengthen observability, health checking and alerting., • Raise the standard of the code around you through review, and bring less experienced engineers on by working alongside them. To be successful, you will need experience building stateful services that stay correct under failure, and a track record of changing a load-bearing system while people depend on it. We're looking for someone who can own a problem area with little supervision and contribute effectively within a fast moving, highly technical team. You'd be a great fit with: • Strong systems engineering skills. Our System Orchestration layer is written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming., • Experience designing and operating networked services (such as gRPC or REST), with a real grasp of error handling, observability and failure modes., • Real experience with a relational database as a source of truth - schema design, migrations against live data, and transactions. We use PostgreSQL., • A track record of getting lifecycle and concurrency right: state machines, timeouts, leases, retries, and the failure modes that only show up under load., • Experience with a scheduler, workflow engine or job queue - Temporal, Airflow, Celery, Slurm, or one you built - or with event-driven systems that react to changes in state., • A habit of settling design questions in writing, with options weighed as peers., • Comfort owning the production behaviour of what you build, not just its correctness in test., • Excellent communication skills both within software and across disciplines., • An interest in helping other engineers get better at the craft, without wanting to stop building yourself. Additional useful experience would include running containerised services in production, Kubernetes, distributed tracing, closed-loop systems that act on measured state, and scientific computing or research facilities.
