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 a practical junior engineer to help us build, commission, and test electrolysers. You will be in the workshop and lab from day one, working alongside senior engineers on stack assembly, rig commissioning, fault-finding, and live test campaigns.
You do not need prior electrolyser experience. We will teach you the electrochemistry and the process side, including hot caustic handling, hydrogen and oxygen safety, and commissioning procedures. In return you will gain broad hands-on experience across mechanical build, thermo-fluid systems, instrumentation, and controls, plus a genuine foot in the door of the UK hydrogen industry.
- Run experimental campaigns: performance characterisation, durability testing, component trials
- Record test data and keep clean test logs
- Support pressure testing, commissioning, and fault-finding
- Build test fixtures and sub-assemblies
- Plumbing and pipework: cutting, bending, fitting tubing, compression fittings, valves
- Trace faults across mechanical, fluid, and electrical systems
- Workshop inventory tracking: consumables, spares, long-lead items
- Write and update test procedures, risk assessments, and as-built drawings
- Work safely around hot caustic, pressurised systems, and flammable gases
Engineering degree (mechanical, automotive, aerospace, chemical, mechatronic), HNC/HND, or hands-on background as a machinist, technician, or fitter. Confident with hand and power tools, basic machining, and measurement kit. Solid engineering fundamentals. Experience with pressurised gas or liquid systems. Familiarity with DAQ or programming (LabVIEW, Python) and CAD (SolidWorks, Fusion 360, Onshape, or similar). Interest in hydrogen, fuel cells, or clean energy. Full UK driving licence.
Maybe a recent graduate who spent more time in the workshop than the lecture hall, or a technician looking to move into R&D. Broad hands-on experience across mechanical build, instrumentation, and test engineering. Small team where you see the impact of your work immediately. Competitive salary and benefits.
If you want to work on hard problems with real climate impact—and help take breakthrough technology from concept to deployment—join us.
