Full job description

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

About us

Electrogenos is 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. Our approach is practical by design: use scalable materials and processes, and validate performance through close collaboration with partners.

If you want to work on hard problems with real climate impact—and help take breakthrough technology from concept to deployment—join us.
