Full-time position. Onsite 5 days a week – Chiswick, London. We’re hiring a Senior Optical Engineer to develop custom optics, lens designs and tolerance strategies that move HoloMem’s product development towards production and help bring our ambitious first product to market. About HoloMem - At HoloMem, we’re building the next generation of mass data storage hardware; highly efficient, long life, and ultra durable. Our pioneering and patented holographic technology encodes data as light within advanced polymers, enabling a resilient and future fit alternative to today’s short lived and energy intensive data storage infrastructure. Over the past 24 months HoloMem has graduated from both the Intel Ignite and Deeptech Labs accelerators, been awarded two Innovate UK Smart Grants, closed a seed+ funding round, and most recently deployed a working HoloDrive prototype to a live data centre to prove the robustness of our system. Off the back of our breakthrough partnership with BDT, the world’s largest tape library manufacturer, we now begin the transition from prototype to product, maturing our validated system into a mass-produced technology platform that enables state of the art data storage performance at scale. We have ambitious plans, and we are now scaling up our West London based team to enable them. Join us. What You’ll Be Doing – You’ll work on the optical systems at the heart of HoloMem’s product development, with a core focus on Zemax-based optical design, lens design, tolerance analysis, supplier feasibility, production intent and cost reduction. This is not a purely simulation-based role. You will need to connect optical design decisions to real assemblies, supplier capability, manufacturing constraints, cost, quality and system performance. You’ll help translate product-level requirements into optical performance targets, tolerance budgets and practical acceptance criteria, then use simulation, supplier input and prototype evidence to close the loop between design intent and real-world performance. You’ll work closely with mechanical engineering so that lens mounting, assembly constraints, thermal behaviour and design-for-assembly decisions are treated as part of the optical system, not downstream packaging problems. You’ll take ownership of defined optical work packages, review optical design work constructively, and support technical decisions around performance specifications, quality controls, cost reduction and design risk. The Specifics About the Role - This role is suited to a senior optical design engineer who has worked on lenses, camera assemblies, custom optics or comparable optical systems, and who understands what changes when an optical design has to move towards production. This role is suited to a Senior Optical Engineer who can demonstrate the ability to: • Design, simulate and optimise optical systems using Zemax OpticStudio, • Develop lens designs, custom optics and beam shaping approaches for production-intent optical systems, • Define, analyse and review optical tolerances, including tolerance stack-up effects across optics, mounting and assembly, • Assess how temperature, material properties and mechanical expansion affect optical alignment, focus or system performance, • Translate optical performance needs into specifications, tolerance budgets and acceptance criteria, • Work with mechanical engineers on lens mounting, dense packaging, optomechanical integration and design for assembly, • Connect optical design choices to manufacturability, cost, supplier feasibility and technical quality controls, • Work with optics suppliers on component specification, tolerance feasibility, cost-down and production constraints, • Correlate optical models with prototype data, supplier feedback and assembly evidence, • Use Python to support optical analysis, modelling, data processing or design review, • Review optical design work constructively, challenge assumptions and help improve the quality of technical decisions across the team Who You Are - You are a hands-on optical design engineer who is comfortable working between Zemax models, lens designs, physical assemblies, supplier constraints and cross-functional engineering decisions. You understand that optical performance is not only set by the lens prescription, but by tolerances, mounting, thermal behaviour, assembly process, supplier capability and how the optical system sits inside the product. You state assumptions clearly, expose the risks in a design and make practical recommendations when the information is incomplete. You are confident enough to challenge existing work constructively, but grounded enough to separate real technical risk from personal preference or over-optimisation. You should enjoy working on problems where time, cost, specification, quality and scalability all matter at once. This role will suit someone who has seen optical design move towards production and understands the compromises required to make a system perform reliably outside a clean design file. Required Experience – • Around 3–5 years of relevant industry experience in optical engineering, • Strong experience using Zemax OpticStudio for optical design, simulation, optimisation and tolerance analysis, • Experience with lens design for optical systems, camera assemblies, optical engines or comparable hardware, • Experience with optical tolerancing and tolerance stack-up analysis, • Experience connecting optical design choices to assembly, cost, quality and manufacturability, • Experience assessing how mechanical mounting, material properties or temperature can affect optical performance, • Experience working with optics suppliers on component feasibility, specification, tolerance limits, cost or production constraints, • Experience supporting production-intent development of lenses, camera assemblies, custom optics or similar optical hardware, • Ability to work independently on defined technical work packages, • Strong cross-disciplinary communication with mechanical, systems and hardware engineering teams, • Clear technical documentation and design review discipline Desirable Skills - • Experience taking optical products or subassemblies into production, • Experience with camera module development, lens stack design or imaging system production, • Experience with beam shaping or custom optics design, • Proficiency with Python for optical analysis, modelling, simulation support or data processing, • Experience with dense optical packaging or constrained lens mounting, • Experience with FMEA, risk management or structured design review processes, • Broader production engineering experience outside optics, • Familiarity with safety, quality or production control requirements for optical hardware, • Knowledge of holography or holographic optical systems, • Experience with cost reduction of optical assemblies or custom optical components, • Experience defining performance specifications, acceptance criteria or technical quality controls for optical systems, • Experience supporting supplier selection, supplier review or manufacturability discussions for optics Benefits At HoloMem - • Competitive salary, • 25 days annual leave, • Employer pension contributions, • Cycle-to-work scheme, • A collaborative, knowledgeable team working on deeply technical, world-positive problems How to Apply - Click apply or send your CV to . Show us what you’ve designed, built, or tested. If you’re excited about the mission, even if you don’t meet every requirement, we’d love to hear from you. HoloMem is an equal opportunity employer. We value diversity and are committed to building an inclusive environment for all.

About Loctax: Loctax is a tax technology company. We build software for tax professionals at large multinationals and advisory firms — helping them with tax research, compliance, risk and governance management across all the jurisdictions they operate in. Founded in 2020, Loctax was acquired by Tax Systems in 2025 and is now part of the UK’s leading corporate tax software group, trusted by thousands of tax and finance professionals. Together with Tax Systems, we are building the very first Tax Operating System — one AI-powered platform where global tax professionals can research, comply, and make decisions without switching between a dozen disconnected tools. This is an early and pivotal moment in that journey. The Opportunity: This is not a role for someone who needs a fully paved road. You will work directly with our Co-founder, GTM Engineer, BDRs, Sales Director, and Account Executives — and you will own pipeline generation from first touch through to qualified meeting. The BDR team is small and there's no fully built playbook that can be handed to you. The upside is real, and so is the expectation. You will have direct influence on how we build our market presence from the ground up. Your work is visible, your impact is immediate, and the role grows with you. There are plenty of opportunities to step into an AE role within 12 months after starting, or switch to something else if you’d like. This role suits someone who thrives in incomplete information, makes sharp decisions with what they have, and consistently finds a way to overachieve — not because they were told to, but because that is simply how they operate. What You’ll Do: Prospecting & Lead Generation: • Build and work a targeted account list of multinational companies across key European markets., • Run outbound sequences across email, LinkedIn, and phone — personalised to the prospect, not templated., • Follow up on inbound leads and event contacts quickly and with purpose., • Run discovery calls to qualify opportunities and understand what is actually driving the prospect’s interest., • Get in front of senior buyers — Head of Tax, VP Tax, CFO — and earn their attention with sharp, relevant outreach., • Keep the CRM clean and your pipeline honest., • Hand off qualified opportunities to Account Executives with full context — not just a name and a company. Collaboration & Knowledge Sharing: • Share what you’re hearing from prospects with the product and customer success teams — we actually use that feedback., • Help position Loctax clearly and credibly in every prospect interaction. Continuous Learning & Process Improvement: • Get deep on the product and the space — you do not need a tax background, but you need to want to understand it., • Help build the sales playbook — you are joining early enough to shape how things are done., • Bring a positive, high-energy approach — things will not always be straightforward, and that is part of what makes it interesting. Requirements: Education & Experience: • 1+ years of BDR or SDR experience in B2B SaaS or professional services., • Comfortable in a metrics-driven environment — and more importantly, comfortable holding yourself to a higher standard than the metrics require., • A track record of overachievement — we want to know what drove it, not just that it happened. Skills & Attributes: • Strong written and verbal communication in English, • Comfortable making a high volume of cold calls and handling objections without losing your cool., • Confident across email, phone, and LinkedIn outreach., • High agency — you do not wait to be told what to do next. You identify the gap, form a view, and move., • Comfortable working with incomplete information — you make reasonable assumptions, act on them, and course-correct rather than waiting for perfect clarity., • Sharp enough to research a senior buyer, understand their business, and write outreach that is actually relevant to them., • Organised enough to run a full pipeline without being micromanaged. Bonus Skills: • Experience with AI-driven outreach and automation tools (Lemlist, n8n, Clay, Claude Code or similar)., • Experience doing detailed account research and qualification at scale using AI tools., • Familiarity with sales triggers and intent signals to sharpen outreach timing and lift conversion rates. Mindset & Motivation: • You hold yourself to a higher standard than the one set for you., • You are energised by ambiguity, not slowed down by it., • You want to understand the business, not just your quota — and you use that understanding to work smarter., • Excited by a role where the rules are still being written and your contributions shape how things are done. What we offer: • Annual leave - enhanced holiday plus any local public holidays., • Birthday day off., • Competitive salary., • Top tech gear., • Learning budget., • Bi-annual team offsites.

It’s still early, still messy in the right ways, and still a place where one strong engineer can have disproportionate impact! The product sits in the agentic AI space, building systems that don’t just assist but actively carry out tasks, make decisions, and improve over time. That means a heavy focus on reliability, orchestration, and real-world performance rather than demo-ware. The Role You’ll join at a level where your influence goes beyond delivery, helping shape both the technical foundations and the product itself.

You’ll likely be product-minded, comfortable making decisions without layers of process, and motivated by building something meaningful alongside other strong engineers. Clear communication matters, as does the ability to influence without relying on hierarchy. This is a fast-moving environment where you’ll need to balance pace with quality and stay focused on outcomes. What They’re Looking For • Experience operating at Senior or Staff level with a strong IC background, • Track record of leading complex technical work or projects, • Strong backend experience, particularly with Golang and TypeScript, • Experience building and scaling systems in cloud environments (AWS or GCP), • Solid understanding of system design and scalable architecture, • Ability to mentor and influence other engineers, • Experience working in fast-paced, product-led environments SR2 and the client are committed to building inclusive, diverse teams and welcome applications from all backgrounds, even if you don’t tick every box. If you’re curious, drop me a note at and we can take it from there.

Moodsonic uses sound to improve how indoor spaces feel. Our platform delivers adaptive soundscapes for workplaces, hospitals, universities, and other shared environments shaping daily life, integrating with hardware, building systems, and an array of applications to respond dynamically to activity levels, time of day, environmental sensors, and user input. The work sits at the intersection of audio, real-time systems, and human experience. The role We are hiring a Senior Software Engineer to own the backend that the entire product stack sits on: services, data layer, identity and authentication infrastructure, partner-facing integration APIs, device communication, and the security posture. You will own, evolve, and build the systems that power our internal tooling, customer-facing applications, partner integrations, and hardware deployments, strengthening what is already in production and shipping what comes next. You will be the technical lead on production engineering, security, and code quality, building on the foundations the team has put in place. As Moodsonic scales, you will keep the platform safe, reliable, and defensible. You are joining a team where colleagues hold deep domain knowledge. You will need to build trust, collaborate well, and lead through influence rather than authority. This is not a management role. The platform is live and growing quickly, with real customers and real consequences. What you'll work on In your first six to twelve months: • Own and evolve the backend platform: services, data layer, infrastructure, APIs. Strengthen what is in production today, design what is missing, and build what comes next, • Own the backend side of how our deployed hardware connects to the platform: ingestion, device authentication, fleet management, and remote provisioning. Visibility and input into on-device code decisions, because device security is platform security, • Own the identity, authentication, and account layer of the platform, • Own and operate our data protection posture across the platform: encryption in transit and at rest, key management, data lifecycle, and recovery, • Own the partner-facing integration APIs end to end, from design through operation. These are the surfaces our customers and hardware partners build against, and their reliability is our reputation, • Own the engineering practices that support our certifications and audit-readiness, • Establish and maintain the engineering standards (testing, review, deployment, monitoring, secure coding) that the team operates by, • Partner with the engineers owning the audio engine and frontend surface on the backend contracts their work depends on What we are looking for Required: • 5+ years shipping and operating production backend systems, including time on-call and in incident response. You know what it feels like when something breaks at 2am and you own the fix, • Operational resilience as a habit: you design for failure, build with recovery in mind, and treat incident learning as a driver of engineering quality, • Strong judgment in small-team environments. You have owned quality yourself rather than inheriting it from process. You can take high-level product, customer, or security needs and turn them into practical technical plans without a big PM or architecture layer handing you a spec, • Deep relational data modeling and schema design. Postgres or equivalent as a daily tool. Strong instincts for migrations, indexing, and query performance under load, • API design experience: you have built and maintained APIs that outlived their first version and you have opinions about versioning, compatibility, and contract discipline, • Identity and authentication systems experience: modern identity protocols (OAuth or similar), session management, role-based access, multi-tenant boundaries. You understand what breaks when these are wrong, • Security mindset in practice, not theory. You think about attack surface, threat models, and access control as a matter of course, with working knowledge of cryptography and data protection fundamentals, • Code quality and observability as habits. Tests, substantive review, documentation, and the instinct to measure how software behaves in production are part of doing the work, not chores after it, • Strong Python for backend services. Comfortable with SQL, Docker, at least one major cloud, infrastructure as code (Terraform, Pulumi, or equivalent), and modern CI/CD practices, • Modern AI development tools are part of how you ship. You stay current as they evolve, adopt what adds value, and use AI to go faster on work you already understand, which is why you catch AI mistakes before they become bugs, • Demonstrated technical leadership through influence, not authority: you raise the bar through code review, standards, and example, and you have earned trust from engineers who were there before you, • Pride in craft, proactive risk-flagging, and the instinct to raise quality bars rather than work around them. Intellectual honesty and the willingness to push back when the right answer is unpopular, • Clear written and verbal communication, particularly when working asynchronously across time zones Valued: • Designing systems that interface with deployed hardware: device fleets, provisioning flows, secure OTA updates, telemetry ingestion, • Shipping to enterprise customers, incident response commitments, and contractual security obligations, • Experience inside a compliance-driven environment (SOC 2, ISO 27001, HIPAA, or equivalent) or building for auditability as a default, • Kubernetes and modern container orchestration, • Additional backend language fluency (Node or TypeScript, Go, Rust) for polyglot service work, • Audio, signal processing, or real-time systems background, • AI and machine learning in product contexts: audio generation, personalization engines, training and serving pipelines Not required but welcome: • Interest in sound, music, acoustics, or the wellbeing applications of audio Team and how we work You will join a small, senior team distributed across the UK, Europe, and the US West Coast. We run a weekly product cadence, work asynchronously by default, and rely on clear written communication to stay aligned across time zones. Compensation and benefits Base salary £65,000 to £85,000, calibrated to experience. Equity will be a material part of the package. Benefits include private medical insurance for UK employees, 28 days paid holiday inclusive of UK holidays, flexible remote-first working. UK right to work is required. How to apply Send a short note, your CV, and links to work you are proud of. Please include three to five sentences on a production system, API, identity/auth, or platform hardening project you owned.

Hands-on senior commissioning engineer to lead the on-site integration work for a UK platform company building the operating system for critical infrastructure. BMS, SCADA, and building automation across NHS estates, data centres, and large commercial sites. You'll be the OKTO face on site during commissioning — configuring controllers, integrating systems, and making the platform actually work in the buildings we deploy into. Working under the Lead OT Engineer, with a clear path to grow as the function expands. About OKTO OKTO is a 33-year-old systems integration business pivoting to become a critical infrastructure platform company. We build CIDE-OS — an operating system for critical infrastructure estates — currently in reference deployment at a major NHS Trust. The platform synthesises operational state from BMS, SCADA, and clinical operational systems into a single honest surface for senior decision-makers. We are based in Lisburn, Northern Ireland, with active project work across the UK. We are a small team at the inflection point between integrator and platform company. Why this role is genuinely interesting If you've been commissioning BMS for a few years, you'll know most senior roles at large contractors involve doing more of the same on bigger projects. This is different. You'll be commissioning into a platform that is becoming a category, working alongside an experienced lead, with real ownership of how the work gets done. Small team, serious work, room to grow. What you will do • Configure and commission BMS, SCADA, and building automation systems for CIDE-OS deployments., • Integrate underlying estate systems with the CIDE-OS data fabric — BACnet/IP, Modbus, KNX, OPC, MQTT, REST APIs, and direct integrations as required., • Work alongside client engineers, M&E consultants, and Tier-1 contractors during commissioning — the OKTO face on site for the technical work., • Document configurations, integration decisions, and operational handovers to professional standards — the audit trail matters., • Identify integration patterns that should be standardised at the platform level — feed insights back to the Lead OT Engineer., • Mentor more junior engineers as the OT function grows. Technical background we are looking for 6+ years of hands-on experience configuring, commissioning, and integrating building systems in commercial-scale projects. Strong working knowledge of at least three of: • Tridium (Niagara framework) — workbench-level configuration, drivers, integration., • Schneider Electric BMS (EcoStruxure Building / StruxureWare / Andover) — configuration, point mapping, integration., • KNX — system commissioning, ETS configuration, integration with BMS layers., • BACnet/IP — point mapping, network configuration, troubleshooting at scale., • Crestron, AMX, or similar AV control systems — useful background; not central, but the integration mindset translates., • SCADA configuration and integration — particularly in critical environments. Sector experience Practical commissioning in commercial-scale estates: Trusts, large commercial buildings, data centres, pharmaceutical sites, university campuses, or industrial process facilities. Strong commercial-scale BMS commissioning experience translates well. How you work • Hands-on and practical — you enjoy making systems actually work, not just designing them on paper., • Methodical — you commission systematically, test thoroughly, and document as you go., • Calm under pressure — commissioning windows are tight and things go wrong; the test is how you handle it., • Honest about progress — you tell the truth about where the work is, including when it is behind., • Client-facing without being sales-y — the senior engineers you work alongside on site are colleagues, not customers. Working pattern Based in either Northern Ireland or London, with regular travel between the two — typically Monday-to-Friday during active deployment phases, quieter weeks based at home. Travel and accommodation costs covered by OKTO. Be honest with yourself about whether that pattern fits your circumstances. Compensation Base salary:£65,000–£85,000 (London-based), depending on experience. Share options available subject to performance and tenure. Contract alternative: 12-month fixed-term contract at £375–£475 per day (inside IR35), depending on experience. Travel and accommodation covered. Standard benefits package. We're not the highest-paying option — the larger BMS players and major contractors will pay more in base salary. What we offer is genuinely interesting work, exposure to a platform becoming a category, and the chance to grow with a small team. How to apply Send a CV and a short covering note to . The covering note matters more than the CV — tell us in plain English what you have built and commissioned, and what you have learned from a project that did not go to plan. We are looking for substance, not polish. First stage is a 30-minute call. Second stage is a practical technical discussion at our Lisburn workshop with the engineering team. Reasonable travel expenses for interview covered.
