Stack & Thermofluidic Engineer

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.

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.

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.
