Operations Manager UK

Electrogenos

OUR MISSION At Electrogenos, we're building technology to make green hydrogen competitive at scale. We focus on reducing the cost and complexity of hydrogen production so it can replace fossil-based alternatives across real-world applications. We're an early-stage team working at the intersection of electrochemistry, manufacturing, and deployment. ABOUT THE ROLE We are looking for an experienced R&D Project Manager to own the delivery of our most important projects — the person accountable for making sure each one is planned properly, moves at pace, and lands on time and in scope. As we scale towards our first international MW-scale pilot deployments, and a manufacturing pathway, the number of moving parts is growing fast. This role exists to bring structure, visibility, and momentum to all of it. The role exists at the interaction of the strategy, operations and technical teams. You will own a portfolio of concurrent projects — from an international pilot deployment, to a manufacturing scale-up, to grant-funded R&D programmes. For each, you will define what needs to be delivered, break it into tasks and milestones, build and maintain the plan, and drive it through to completion. You will coordinate delivery across the whole company — aligning scientists, engineers, and external partners on priorities, dependencies, and deadlines — while giving the founders and the board a clear, honest line of sight on where every project stands. This is a senior coordination and delivery role. You will be responsible for owning the plan, driving the critical path, and making sure the science, and everything around it, actually lands. You will be the steady, organised force that keeps ambitious projects on track and holds delivery to the timeline. TASKS * Define project scope, deliverables, and milestones for each project, working with the founders and technical leads to turn ambitions into a clear, realistic plan * Build and own detailed project plans — Gantt charts, critical paths, dependency maps, and timelines — and keep them live as reality changes * Coordinate delivery across R&D, engineering, and external partners: align owners on what needs to happen, in what order, and by when * Own the critical path — anticipate blockers, resolve dependencies, and keep work moving so projects don't slip * Own the risk and issue register: surface risks early, drive mitigations, and escalate what needs a founder's decision * Run project reviews and steering meetings — driving decisions, tracking commitments, and keeping delivery on plan * Read and synthesise technical documents well enough to understand real status and ask the right questions (you don't need to be the expert) * Give leadership and the board visibility — clear status reporting, dashboards, and straight read-outs on what's on track and what isn't * Hold delivery to account across several projects in parallel without letting any of them drift ESSENTIAL SKILLS * 5+ years in project or programme delivery, or 3+ years having independently owned complex, multi-workstream projects end to end * A track record of actually landing technical projects on time — owning the plan, not just supporting someone else's * Fluency with project planning tools (e.g. MS Project, Smartsheet, or equivalent) and genuine command of Gantt charts, critical path, and dependency management * Strong stakeholder management — able to align, influence, and hold technical and non-technical people to delivery commitments, at all levels * Excellent written communication and structured, clear reporting to leadership * Solid risk and issue management * Comfortable reading technical documentation and operating in a scientific or engineering environment * Autonomous and senior in mindset — owns outcomes and drives delivery without supervision DESIRABLE SKILLS * Project management experience within R&D, engineering, deep-tech, or another hard-science or regulated environment * A recognised project management qualification — PRINCE2 and/or APM PMQ (or working toward one); PMP is a plus given our international projects * Experience delivering hardware, manufacturing scale-up, or pilot and commissioning projects * Familiarity with grant-funded or publicly funded projects (Innovate UK, Horizon Europe, or similar) * Comfort coordinating delivery across countries and time zones * Spanish language skills is a plus YOUR PROFILE You're an experienced delivery owner — the person leadership trusts to take an ambitious, complex project and make it land. You've spent years defining what needs to happen, building the plan, and driving it to the finish, and you take real pride in projects that arrive on time and in a leadership team that always knows exactly where things stand. You think in timelines and dependencies, you stay calm when plans move, and you're as comfortable driving a technical lead to hit a milestone as you are giving a CEO a straight answer on where a project really stands. You're drawn to hard, meaningful problems and to a company where the projects genuinely matter. You want to own delivery, not administer it, and you're looking for a role with real scope that grows as the company does. WHY US? * Own the delivery of the projects that define our next few years — from international pilot deployments to manufacturing scale-up * Direct access to the founders and board-level visibility from day one * Work at the frontier of green hydrogen, on a technology with genuine potential to change the economics of the industry * Real breadth and variety — no two projects are the same * A role that grows as we scale from a small team toward 20+ people, with a path into programme and delivery leadership * A mission-driven team building real technology for the energy transition * Competitive salary, discussed during the interview process Visa sponsorship is available for the right candidate.

Electrogenos

OUR MISSION At Electrogenos, we’re building technology to make green hydrogen competitive at scale. We focus on reducing the cost and complexity of hydrogen production so it can replace fossil-based alternatives across real-world applications. We’re an early-stage team working at the intersection of electrochemistry, manufacturing, and deployment. ABOUT THE ROLE We are looking for an engineer with a few years of established experience to own the thermal, fluid, and pressure aspects of our alkaline electrolyser stack and balance-of-plant systems. We are developing enclosed multi-cell modular stack architectures with strong parallels to modern chlor-alkali cell design. As we scale from kW to MW-class systems, we need someone who understands electrolyte circulation, gas-liquid separation, thermal management at 80–100°C, and pressure balancing between hydrogen and oxygen sides. This is a hands-on as much as analytical role. You will model and simulate, but you will also be on the shop floor commissioning what you designed, troubleshooting what didn’t work, and iterating in real time. We need someone equally comfortable with a process simulation and a pipe wrench. We are not looking for another team leader — we need someone who wants to get their hands dirty and go deep on the engineering. Direct experience with alkaline water electrolysers or chlor-alkali cell technology is strongly preferred. However, if you bring deep thermal engineering and process design experience from a related field and can demonstrate strong thermofluid fundamentals, we want to hear from you. As we move toward our first pilot deployments — including at international partner sites — you should be comfortable travelling and supporting commissioning beyond the Milton Park workshop. Visa sponsorship is available for the right candidate. TASKS * Own thermofluid design of multi-cell alkaline electrolyser stacks: flow distribution, gas management, thermal behaviour * Design and optimise electrolyte circulation for uniform distribution across cells in enclosed modular configurations * Develop thermal management strategies for operation at 80–100°C * Model and validate pressure balancing between O₂ and H₂ sides, including differential pressure control and its safety implications * Design BOP from P&ID through to component specification: pumps, heat exchangers, separators, valves, piping * Perform mass and energy balances across operating conditions * Specify materials for hot KOH service * Commission, test, and troubleshoot the systems you design — hands-on on the shop floor * Contribute to HAZOPs and pressure system compliance (PED, PSSR) * Analyse test data and feed insights back into design iterations * Support the coordination and commissioning of pilot deployments at partner sites, including internationally ESSENTIAL SKILLS * Degree in Mechanical, Chemical, Process, or Thermal Engineering * Approximately 3 to 6 years of relevant experience * Strong thermofluid engineering fundamentals: heat transfer, fluid mechanics, two-phase flow, thermal system design * Experience with process design: P&ID development, mass and energy balances, component specification * Understanding of gas-liquid separation and thermal management in process systems * Knowledge of materials selection for aggressive chemical environments * Hands-on and rig-competent: comfortable commissioning, plumbing, and troubleshooting the hardware you design * Comfortable working with pressurised systems DESIRABLE SKILLS * Direct experience with alkaline water electrolysers or chlor-alkali cell technology (strongly preferred) * Experience with multi-cell, bipolar, or enclosed cell stack configurations * Thermal engineering experience: heat exchanger design and selection, thermal transient analysis, cooling system design * Process engineering experience in chemical, petrochemical, or energy sectors * Experience with enclosed or zero-gap cell designs * Process simulation or CFD experience (ANSYS, COMSOL, Aspen, or similar) * PED, PSSR, or EN 13445 compliance * Hydrogen safety, DSEAR, ATEX * PP, PVDF, or PFA piping for caustic service * Willingness to travel internationally for pilot commissioning and partner site work * Spanish language skills  * Full UK driving licence YOUR PROFILE You’ve spent a few years working on alkaline electrolysers, chlor-alkali cells, or in thermal and process engineering in a demanding industrial environment. You understand thermofluid realities — how flow distributes, where heat builds, what happens when a pressure balance shifts. You’re as comfortable with a process model as you are tracing a problem on the shop floor. You want to own the domain in a company where the stack architecture is still being shaped, not execute someone else’s spec. The prospect of helping commission our first pilot systems — including at international partner sites — excites rather than daunts you. WHY US? * Own the entire thermofluid and BOP domain for a next-generation alkaline electrolyser * Shape stack architecture where design decisions still matter * Your models get validated on real hardware in the same building * Small team, high ownership, direct collaboration with the CTO * Be involved in our first international pilot deployments * Competitive salary and benefits
