Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the time taken to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to efficiently generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts. The workloads that push to the limits of the current frontier are already transformational; it is the technical and economic limits on inference speed that are constraining progress. The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems.

The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems. Fractile is building a full-stack AI accelerator from the ground up, and the compiler team sits at the heart of how we deliver performance. As the Engineering Manager for Compilers, you will build and lead a team of 10+ engineers developing the compiler stack for our novel AI acceleration hardware, with direct responsibility for enabling industry-leading LLM inference performance on Fractile’s accelerators. This is a hands-on technical leadership role in a fast-moving, collaborative environment where the compiler team works closely with hardware, driver, runtime and ML engineers across the stack. If you want to shape the architecture of a compiler from first principles, build a world-class team around it, and have your work directly determine the performance of next-generation AI hardware, this is the role. Proven track record of leadership experience managing a high-performance development team and delivering consistently outstanding outcomes. Proven experience in compiler development, with experience of machine learning compilers and industry standard technologies such as MLIR or TVM being a significant advantage. Up-to-date knowledge of machine learning techniques and technologies A good understanding of computer architecture and performance optimisation techniques. Excellent C/C++ skills and solid experience of industry standard development tools and technologies. A creative and innovative mindset, and a willingness to take ownership and drive results in a fast-paced environment. This is a young company doing hard things, at the intersection of novel silicon and the software stack that makes it useful. You’ll be building and leading a compiler team as the hardware it targets is still taking shape, which means making architectural decisions against a specification first, then a simulator, then early silicon. The IR design, the lowering strategy, the execution model: you’ll help define all of it before you can run it on real hardware. That takes comfort with ambiguity and the ability to make good calls with incomplete information. If that sounds frustrating, this probably isn’t the role. If that sounds like the interesting part, we should talk. The boundaries here are soft by design. The compiler team works closely with hardware architects, kernel engineers, runtime teams and ML researchers. You’ll need to understand enough of what sits above and below your layer to make good decisions at the boundary, and to build a team that can do the same. That breadth is a feature of the job, not a distraction from it. You’ll be there when the first model runs end to end on Fractile silicon. When the lowering strategy you helped design produces a result the hardware team didn’t think was possible yet. When the team you hired and grew ships something that goes into every rack we sell. We want a team that reflects the world it’s building for, and we welcome applicants from every background, including those whose path here hasn’t been straight. We care that you’re energised by this kind of work, that you build and develop great engineers, and that you make the people around you better. Come build it with us. Competitive salary: A competitive salary reflective of your experience and the specialist nature of the role.

Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the time taken to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to efficiently generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts. The workloads that push to the limits of the current frontier are already transformational; it is the technical and economic limits on inference speed that are constraining progress. The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems. As Processor Architect, you’ll define and drive the architecture of our core compute engines, ISA definitions and programming models through to memory hierarchies, and on-chip interconnects.

Developer Experience sits within the Software organisation at Fractile, which is responsible for developing a full software stack for our groundbreaking AI inference systems. That's everything from ML compilers, device drivers and systems firmware, application level runtime and ecosystem integrations, ML and compute libraries, great developer tooling and a full portfolio of simulators, through to datacenter scale workload deployment solutions. At Fractile, we know that a fantastic software stack is a critical and central part of any AI inference solution and it sits at the heart of everything we're doing. To build hardware that doesn't yet exist, you first have to model it — with precision, depth, and an eye for the trade-offs that matter. At Fractile, high-fidelity pre-silicon models shape our architecture, performance, and product design long before hardware exists. The Simulation team includes C++ and SystemC specialists, verification and validation engineers, system architects, and embedded engineers. This is not a support function — it is the group that defines how Fractile's hardware behaves. As a Modelling Engineer you will develop the pre-silicon models of Fractile's AI acceleration hardware, enabling architectural exploration and definition, functional modelling, performance modelling and bottleneck analysis, and early software development on virtual platforms. You will work closely with hardware, software, and ML teams in a true hardware–software co-design loop. You have a genuine curiosity for hard problems and the depth to operate across architecture, performance, and functional correctness. You understand that the models you build will shape the architecture of Fractile's accelerator, determine performance trade-offs, enable early runtime and compiler development, unblock software teams months before silicon exists, and reduce risk across the entire product lifecycle. You take that responsibility seriously and bring the rigour it demands. • Experience in pre-silicon modelling of complex semiconductor IP, • SystemC or equivalent modelling frameworks, • C++ for high-performance simulation, • Performance modelling and architectural analysis, • Verification and functional modelling, • Experience with ML workloads or ML accelerator architectures, • Prior startup or small-team experience, • Competitive salary: A competitive salary reflective of your experience and the specialist nature of the role, • Equity & Ownership: meaningful equity so everyone shares in the value creation, • Benefits: Private Medical, Dental and Vision, Contributory Pension, 25 Days holiday plus bank holidays and Life/Critical Illness Insurance, • Diverse & fun office: we believe the hardest problems get solved by the broadest range of minds.

The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems. Silicon Infrastructure Engineer Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the time taken to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on.

Ardent is an infrastructure and regeneration specialist. They understand that the value of land lies in its potential to improve lives and create a more sustainable future. The business supports major infrastructure projects across the UK and Ireland, working with clients in the energy, transport, and renewables sectors, city and town regeneration, as well as offering comprehensive services in land referencing, promotion, implementation, and compensation. They have the largest team of CPO surveyors in the UK and Ireland and are the market leader in both Land Assembly & Compulsory Purchase and Development Consent Order (DCO) land advice. Their track record speaks for itself with over 35 years in business, 100+ DCOs submitted, involvement in more than 150 major DCO, CPO and TWAO projects, and experience acting as the property expert at over 100 DCO examinations to date. The business has recently moved to a regional operating model, with presence in the East of England, London & South East, South West, Midlands, North West, North East and beyond; bringing its former valuation & compensation and land assembly teams together into a single land services function in each region. Ardent's growth isn't just a future ambition, it's already well underway, having grown into the largest CPO team in the UK and Ireland and the market leader in Land Assembly & Compulsory Purchase Advice. Ardent is looking for a leader to establish its presence in Bristol, building a credible, visible operation to increase coverage and visibility across the South West and South Wales, and to capture significant client opportunity across the wider region. Ardent already has a Bristol presence, which this role is set to build on, growing it into a fully-fleged office with its own identity, pipeline and people, in a market where there is already significant client demand and opportunity. As the gateway into South Wales, Devon and Cornwall, Bristol represents new territory of real strategic importance to the business. Land Services is also seen internally as the key engine of Ardent's projected growth. The Bristol office also has a strong existing national pipeline, including relationships with utility, transport, and local / combined authority frameworks. The first six months are about establishing a strong, credible presence and starting to recruit; the following one to two years are about building a Bristol and South Wales-focused pipeline of work. The ambition is a team of 10–15 people within 12 months, which is an exciting scale of growth that reflects just how much Ardent wants to invest in Bristol's future. The successful candidate will: • Establish a credible, visible Ardent presence in Bristol and start recruiting from day one, • Build and lead a local team, with an ambition of 10–15 people within 12 months, • Generate work by winning new relationships and leveraging existing ones, • Take on utilisation responsibility and increasing autonomy over recruitment and client decisions, • Represent Ardent and help shape a still-new office-lead group across the business The purpose of this role is to establish Ardent's presence in Bristol, building, and recruiting a local team, and generating work by winning new relationships and leveraging existing ones. The initial focus is on Land Services, with a long-term ambition to grow all of Ardent's service lines in Bristol: Land Services, Land Referencing, Stakeholder Engagement & Communications, Consents Management, and Complex Cases. Although the P&L responsibility sits with the Head of Land Services, the role carries utilisation responsibility and growing autonomy over recruitment and client decisions, with potential flexibility to offer fuller P&L autonomy for a suitably senior, established candidate over time. The preferred candidate will have the following experience: • Chartered Surveyor with a professional practice/consultancy background, • Technically strong in the DCO/NSIP consenting regime, with a working understanding of valuation, • Sector experience is preferred, yet candidates from any sector are of interest, • Ideally an established leader, or an ambitious Senior Associate or Associate Director ready for progression Ardent's purpose is straightforward: delivering life-improving change for communities and future generations. It's a mission the leadership team treats as something to be lived, not just communicated. The business has grown on the strength of being a market leader in land and consents advice, and is now working to a defined plan to reach 500+ people and £100m revenue by 2035, while keeping the personal, collaborative culture that got it here. That culture is shaped by five values Ardent asks everyone to live by day to day: a thirst for knowledge, owning what you do, being the difference, enjoying the journey, and adapting as the business and its markets change. Career development is treated as a genuine priority. Ardent invests in structured training and development, supports people toward the qualifications they need, and has a strong record of promoting from within, with several current directors and senior consultants starting as Assistant Surveyors or Assistant Consultants. For someone joining a region during its build-out phase, that same commitment to backing people applies just as much to building a team locally. Ardent's people also point to the variety and significance of the projects on offer, from HS2 and Sizewell C to major regeneration schemes like the Brentford Football Club stadium redevelopment, and to a deliberate effort to give people breadth across sectors rather than siloing them on one scheme. #J-18808-Ljbffr

Kaluza is the Energy Intelligence Platform, turning energy complexity into seamless coordination. We help energy companies overcome today’s challenges while accelerating the shift to a clean, electrified future. Our platform orchestrates millions of real-time decisions across homes, devices, markets and grids. By combining predictive algorithms with human-centred design, Kaluza makes clean energy dependable, affordable and adaptive to everyday life. With teams across Europe, North America, Asia and Australia, and a joint venture with Mitsubishi Corporation in Japan, we power leading companies including OVO, AGL and ENGIE, as well as innovators like Volvo and Volkswagen. Kaluza runs the billing and payments engine behind some of the world's biggest energy retailers. This role builds and evolves the platform other engineering teams build on top of: the shared APIs, integration patterns, and technical standards that let billing and payments capability get built once and reused everywhere, instead of rebuilt separately for every new market or client relationship. That matters because of where Kaluza is headed: as we grow into new markets and take on more of the world's largest energy retailers as clients, having a consistent, well-designed API platform is what lets new capability get adopted quickly and safely across every team that needs it, rather than each team solving integration and standards problems on its own. Getting this right directly shapes how fast Kaluza can extend billing and payments capability to new markets and clients. We're also in the middle of reorganising how this part of the business works, moving toward one shared global core that every market configures rather than rebuilds. This role's remit, API platform and standards, is one of the technical foundations that shift depends on. • You’ll own system design and architecture for the API Platform and Standards squad, not just a single service., • You’ll create and challenge product and engineering proposals, backing design trade-offs with data., • You’ll diagnose and resolve complex technical and product issues, including in areas outside your immediate domain., • You’ll establish architectural patterns and technical standards that other teams build on top of., • You’ll take ambiguous, loosely-defined technical requirements and turn them into a concrete plan others can execute against., • You’ll influence engineering leadership, product, and adjacent squads to bring clarity and alignment on technical direction., • You’ll mentor and upskill engineers beyond your immediate team, contributing to a wider learning culture. Ideally you’ll have/be • Have deep technical expertise applied to system design and architecture ownership across a squad, not just a single team or service., • Be able to create and challenge product and engineering proposals and make design trade-offs, backed by data., • Have a track record diagnosing and resolving complex technical and product issues, including in domains you aren't already close to., • Be skilled at establishing and driving adoption of architectural patterns and technical standards that other teams build on top of., • Be comfortable taking ambiguous, loosely-defined technical requirements and turning them into a concrete plan others can execute against., • Be accomplished at influencing both upwards and outwards, bringing clarity and alignment to engineering leadership, product, and adjacent squads on technical direction., • Have a track record mentoring and upskilling other engineers, and fostering a learning culture beyond your own immediate team., • Be comfortable operating in a high-integrity data domain (billing or payments), where reliability, security, and auditability come before speed., • Have demonstrable customer obsession and a working-backwards practice: start from the problem other engineering teams or end customers have, and design the simplest platform capability that solves it., • Have demonstrable record of applying AI/LLMs to deliver customer impact, not just adopting AI tooling internally., • Direct experience with API gateway, versioning, or developer-experience standards work at scale., • Direct experience in billing, payments, or financial-services domains., • Experience operating a "global core, configurable edge" or multi-market platform model (one engine, configuration at the edge, no client-specific forks of core logic). We offer flexible working, with an expectation of 3 days a week in the office. This gives us the best of both: real time together to collaborate and build relationships, with the flexibility to work in the way that suits you best the rest of the week. Here at Kaluza we have five core values that guide us as a business: Play to win, Solve the real problem, Build trust every day, Own the outcome, Go further together. • Pension Scheme, • Discretionary Bonus Scheme, • Private Medical Insurance + Virtual GP, • Life Assurance, • Access to Furthr - a Climate Action app, • Free Mortgage Advice and Eye Tests, • Perks at Work - access to thousands of retail discounts, • 5% Flex Fund - to spend on the benefits you want most, • 26 days holiday, • Progressive Leave Policy - With no qualifying service periods, including 26 weeks full pay if you have a new addition to your family, • Personal Learning Budget - Upskill, learn and grow!, • Home Office Budget And more! We’re keen to meet people from all walks of life — our view is that the more inclusive we are, the better our work will be. We want to build teams which represent a variety of experiences, perspectives and skills, and we recognise talent on the basis of merit and potential. We understand some people may not apply for jobs unless they tick every box. But if you're excited about joining us and think you have some of what we're looking for, even if you're not 100% sure, we'd still love to hear from you.

Kaluza is the Energy Intelligence Platform, turning energy complexity into seamless coordination. We help energy companies overcome today's challenges while accelerating the shift to a clean, electrified future. Our platform orchestrates millions of real-time decisions across homes, devices, markets and grids. By combining predictive algorithms with human-centred design, Kaluza makes clean energy dependable, affordable and adaptive to everyday life. With teams across Europe, North America, Asia and Australia, and a joint venture with Mitsubishi Corporation in Japan, we power leading companies including OVO, AGL and ENGIE, as well as innovators like Volvo and Volkswagen. Kaluza runs the billing and payments engine behind some of the world's biggest energy retailers. Every bill sent and every payment collected across Kaluza's markets increasingly runs through one shared core platform, and GBPA exists to build and run that core, so foundational billing and payments capability gets built once and reused everywhere, rather than rebuilt separately for every new market or client relationship. That matters because of where Kaluza is headed: as we grow into new markets and take on more of the world's largest energy retailers as clients, rebuilding core billing and payments capability separately for each one is slower, costlier, and more error-prone than building it once and configuring it at the edge. Getting this right directly shapes how fast Kaluza can bring new markets and clients onto the platform, and how reliable that platform is once they're on it. We're also in the middle of reorganising how this part of the business works, moving from building billing and payments capability separately per area toward one shared global core that every area configures rather than rebuilds. Senior Engineering Managers across GBPA sit at the centre of that shift, each owning two domains rather than a single team. Responsibilities include: • You'll lead engineering across two GBPA domains through complex, ambiguous, cross-squad initiatives., • You'll own technical and product strategy across both domains simultaneously, rather than handing strategy off to a single team., • You'll diagnose systemic and organisational issues using deep domain knowledge, not just resolve team-level technical problems., • You'll manage cross-functional stakeholders across Product, Delivery, and adjacent engineering teams to align roadmap and trade-offs., • You'll carry full people‑leader ownership for both teams: goal-setting, performance and pay conversations, hiring and recruitment., • You'll operate in a high-integrity data domain (billing and payments) where reliability and reconciliation come before speed. Ideally you'll have/be • Have a proven track record leading engineering team(s) through complex, ambiguous, cross-squad initiatives - not single-team delivery., • Have experience owning technical and product strategy across multiple domains or services simultaneously., • Have a track record of diagnosing systemic or organisational issues and resolving them with deep domain knowledge, not just fixing team-level technical problems., • Be a strong cross-functional stakeholder manager, working with Product, Delivery, and adjacent engineering teams to align roadmap and trade-offs., • Have full people‑leader experience: goal-setting, performance and pay conversations, hiring and recruitment for the team(s) you lead., • Be comfortable operating in a high-integrity data domain (billing or payments), where quality and reconciliation matter as much as delivery speed., • Have a demonstrable record of applying AI/LLMs to deliver customer impact, not just adopting AI tooling internally., • Have demonstrable customer obsession and a working-backwards practice: start from the customer problem and ship the simplest solution that solves it, rather than the most sophisticated one available., • Have a track record of successfully navigating complex stakeholder and leadership dynamics, influencing the wider organisation beyond your direct scope to improve product quality and team experience., • Direct experience in billing, payments, or API platform domains., • Experience operating a "global core, configurable edge" or multi-market platform model (one engine, configuration at the edge, no client-specific forks of core logic)., • Experience mentoring senior engineers toward people‑leadership roles. We offer flexible working, with an expectation of 3 days a week in the office. This gives us the best of both: real time together to collaborate and build relationships, with the flexibility to work in the way that suits you best the rest of the week. Here at Kaluza we have five core values that guide us as a business: Play to win, Solve the real problem, Build trust every day, Own the outcome, Go further together. • Pension Scheme, • Discretionary Bonus Scheme, • Private Medical Insurance + Virtual GP, • Life Assurance, • Access to Furthr - a Climate Action app, • Free Mortgage Advice and Eye Tests, • Perks at Work - access to thousands of retail discounts, • 5% Flex Fund - to spend on the benefits you want most, • 26 days holiday #J-18808-Ljbffr

Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the time taken to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to efficiently generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts. The workloads that push to the limits of the current frontier are already transformational; it is the technical and economic limits on inference speed that are constraining progress. The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems. We build the control chain that powers on, monitors, updates, and protects devices and racks across bare metal, RTOS, and embedded Linux. We also build the communication mechanisms that connect devices to each other and to the host. Security runs through all of it. A chain of trust from the hardware up to the rack management plane: the root of trust each controller boots from, the signed updates that reach the fleet safely, the identity that lets a device prove what it is, the authenticated channels the controllers and devices talk over, and the runtime protections that keep the host Linux kernel and the on-die firmware trustworthy long after boot. These are the layers that let operators rely on the hardware. You’d be deeply involved in that security across the chain, making it real in software. You’ll work hand in hand with our architecture and hardware teams, bringing the software and system-level view: turning threat models into concrete mechanisms in bare metal, RTOS, and Linux, then designing, prototyping, and validating them. Some of the calls in this model are still open, and you’ll help shape them. We want engineers who understand security from the inside out. You know how the root of trust, boot chain, key hierarchy, and secure interconnects actually work under the hood, not just how to switch them on. In this role, the security of your software solutions depends entirely on how well you understand the hardware beneath it. Some of the protections we rely on live in silicon, some in software, and part of the skill is knowing which belongs where. We’re looking for people who know both sides well enough to build the mechanisms that close whole classes of bugs by design. We’re not heavy on levels here! Whether you’d call yourself senior, staff, principal, or lead, what matters is depth of security judgement, system-level experience, and working well with the engineers around you. If you’ve worked deep in the security of real systems and like to get your hands on the code and the systems around it, we’d like to hear from you. • Shape the security of the control chain (device, board, chassis, and rack controllers): threat models, trust boundaries, and a coherent secure-by-design approach across all platforms, • Design and help build secure boot and the root of trust on each controller: verified/measured boot, signing and verification, anti-rollback, and locking down debug and privileged access in production, • Secure the interconnects, between controllers and between devices and the host, with authentication, integrity, and additional protections where needed, • Design and build the cryptographic mechanisms: key hierarchies, provisioning and storage, device identity, and remote attestation so the fleet can prove what it’s running, • Make firmware updates safe end to end: signed images, rollback protection, staged rollout, and clean recovery, across every hop of the chain, • Protect the running system, not just boot: harden the host Linux kernel and the on-die firmware, • Work closely with hardware and the rest of the software team to build security into the product, running threat-model reviews, triaging vulnerabilities, and driving fixes to closure We expect you to know the fundamentals, and to have real, practical experience across several of these: • An adversarial mindset and sharp threat-modeling instincts: trust boundaries, assets, attacks, and honesty about residual risk, • Hands-on experience with the core security primitives in software and in silicon: secure boot, root of trust, cryptography, and key management, including how they’re implemented and where they can fail, • Secure protocol and channel design between components, • Strong C and Rust, and the instinct for memory safety and defensive coding that low-level security work needs, • Experience building, not just using, security mechanisms: a secure-boot chain, key hierarchy, or attestation flow you shaped That’s the core. We get especially curious about your application when you also bring some of the following. Very few candidates tick every box here, and we don’t expect you to: • Attestation at boot and at runtime, and management-plane protocols (DICE, IETF RATS, SPDM, MCTP, PLDM; confidential-computing directions like TDISP), • Hardware building blocks and firmware/Linux hardening (HSM, TPM, secure element, Caliptra, secure debug; open firmware/boot projects, image minimisation), • Assurance and resistance (supply-chain security with SBOM and SLSA, fuzzing and testing, standards like NIST 800-series, Common Criteria, OCP incl. S.A.F.E., TCG/DMTF; physical and side-channel awareness), • AI/LLM-assisted security tooling, and RISC-V / GPU / ML-accelerator experience This is a young company doing hard things, balanced across hardware and software. We’re building the software layer for a whole inference system as it takes shape, so you’ll often be securing systems ahead of the hardware: reasoning about a threat model against a specification first, then a simulator, then early boards. You’ll work with incomplete information and watch it get sharper with every iteration. That takes comfort with ambiguity and a bias for action. If that sounds daunting, this may not be the role. If it sounds like the fun part, we should talk. Boundaries between areas are soft here. Security touches every layer, so you’ll work across bare metal, RTOS, and Linux, and alongside the architecture and hardware teams as much as the rest of the software team. That breadth is a good part of the job. You’ll be there for first bring-up, the first secure boot that verifies, the first device that attests itself, the first clean end-to-end run. A piece of what you built will live in silicon and in every rack we ship. We want a team that reflects the world it’s built for, and we welcome applicants from every background, including those whose path here hasn’t been a straight line. We care that you’re excited by this kind of work, that you bring security rigour, and that you make a team better. Come build it with us. • Competitive salary: A competitive salary reflective of your experience and the specialist nature of the role., • Equity & Ownership: meaningful equity so everyone shares in the value creation, • Benefits: Private Medical, Dental and Vision, Contributory Pension, 25 Days holiday plus bank holidays and Life/Critical Illness Insurance., • Diverse & fun office: we believe the hardest problems get solved by the broadest range of minds.

Job no: 502909 Work type: Experienced Professional Location: Kings Langley UK, Bristol UK Categories: Graphics We are building a silicon engineering platform that turns a commit of GPU/AI hardware code into an orchestrated workflow automation that proves it is ready for customer release, including an ML/AI layer that learns to predict how to get there in the fewest workloads possible. This is a large transformation project with executive sponsorship, starting from a clean-sheet design. Designing semiconductor IP involves many tool flows: static analysers, theorem provers, simulation farms running tens of thousands of randomised tests every night, physical design tools that estimate future speed and power needs of silicon. These tools run on a variety of compute platforms - grid, emulator, FPGA, silicon boards. At many companies, including ours, such a stack is held together by decades of scripts, tribal knowledge and manual steps. To replace it, we are building a modern orchestration platform to that coordinates long-running, resource-intensive compute jobs. Our goal is to break monolithic, hard-to-debug pipelines into small, composable, independently testable building blocks - with clear observability and intelligent failure handling. You do not need to know anything about semiconductor hardware; the tools are black boxes with defined inputs, outputs and exit codes, and we have engineers available to explain the domain. What we need is good software engineering, because underneath the domain is a big distributed-systems problem - with orchestration at scale, scheduling around scarce resources, content-addressed caching, data engineering, and correctness problems You will own the application-layer design: the orchestration logic, task/flow abstractions, data models, and the interfaces those components expose. You'll work closely with a principal platform/infrastructure engineer who owns deployment, security, and networking concerns - freeing you to focus on writing clean, well-tested, maintainable orchestration code. Your engineering principles and the quality of your craft matter more to us than prior exposure to our domain and stack, and we'll cover specifics in interview. You will: • Design and implement orchestration logic using a modern workflow engine (e.g. flows, subflows, and tasks in a Prefect-like system), decomposing monolithic pipelines into small, reusable, independently testable units., • Apply solid software design principles (SOLID, separation of concerns, composition over inheritance) to keep orchestration code maintainable as complexity grows., • Define clear, strongly-typed data contracts between pipeline stages (e.g. using Pydantic or similar), favoring lightweight references/pointers over passing large payloads through the orchestration layer., • Design retry, checkpoint, and resume logic so long-running jobs can recover from failure without re-doing completed work., • Implement human-in-the-loop patterns: pausing pipelines for review/approval, and cleanly resuming or rerouting execution based on human input., • Write thorough automated tests (unit, integration) for orchestration logic, including failure-path and edge-case coverage - treat testability as a first-class design constraint, not an afterthought., • Build observability into the application layer: structured logging, metrics extraction, and clear status/error reporting surfaced to end users., • Collaborate with the platform/infrastructure lead to consume infrastructure cleanly (secrets, environment config, execution targets) via well-defined interfaces, without hardcoding infra assumptions into application code., • Participate in code review, championing readability, composability, and pragmatic simplicity over premature abstraction., • Contribute to technical documentation and onboarding materials as the codebase and patterns mature. Committed to making your customers, stakeholders and colleagues successful, you're an excellent communicator, listener and collaborator who builds trusted partnerships by delivering what you say, when you say. You're curious, solutions orientated and a world-class problem solver who constantly seeks opportunities to innovate and achieve the best possible outcome to the highest imaginable standard. You will have: • Experience of professional software development, with a strong command of Python (preferred) or an equivalent modern, strongly-typed-capable language., • Demonstrated understanding of SOLID principles, OOP design, and composition-based architecture - able to explain trade-offs, not just recite acronyms., • Proven ability to write testable code: dependency injection, mocking/stubbing external systems, clear separation between I/O and business logic., • Experience building composable software: small, well-scoped modules/functions/classes that combine predictably, rather than large monolithic scripts., • Comfortable with asynchronous programming (e.g. Python asyncio) for coordinating external process execution and I/O-bound work., • Experience designing data models/schemas (e.g. Pydantic, dataclasses, or equivalent) and using type checking to prevent integration errors., • Solid understanding of error handling and failure-mode design: retries, idempotency, graceful degradation., • Familiarity with version control workflows (Git), CI pipelines, and automated testing frameworks (pytest or equivalent)., • Comfortable working in Linux environments and calling out to external CLI tools/subprocesses safely. You might also have experience of the following: • Direct experience with a workflow orchestration framework (Prefect, Airflow, Dagster, or similar)., • Experience with containerization (Docker, or HPC-oriented tools like Apptainer/Singularity)., • Exposure to systems that coordinate with external schedulers/queues (HPC job schedulers, batch systems, message queues)., • Experience building internal developer tooling or platform-as-product style systems (i.e., building things other engineers build on top of)., • Basic familiarity with cloud services (Azure preferred) and infrastructure concepts (you won't own these, but conversational fluency helps collaboration). Imagination is a UK-based company that creates silicon and software IP designed to give its customers an edge in competitive global technology markets. Its GPU and AI technologies enable outstanding power, performance, and area (PPA), fast time-to-market, and lower total cost of ownership. Products based on Imagination IP are used by billions of people across the globe in their smartphones, cars, homes, and workplaces. We need your skills to help us continue to deliver technology that will impress the industry and our customers alike, ensuring that people everywhere can enjoy smarter and faster tech than ever before. Bring your talent, curiosity and expertise and we'll help you do the rest. You'll be part of one of the world's most exciting companies who are one of the leaders in semiconductor IP solutions.
