Our mission at Electrogenos is to build 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 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.
Tasks:
- Assemble electrolyser stacks and test rigs: torque sequences, sealing, leak checks
- 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
- Fit and route instrumentation: thermocouples, pressure transducers, flow meters, level sensors
- Trace faults across mechanical, fluid, and electrical systems
- Workshop inventory tracking: consumables, spares, long-lead items
- Source parts, raise purchase requests, chase suppliers
- Write and update test procedures, risk assessments, and as-built drawings
- Work safely around hot caustic, pressurised systems, and flammable gases
Essential Skills:
- 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
- Basic instrumentation literacy: pressure, temperature, flow, level
- Safety-first approach
- Writes clearly and takes notes without being asked
- Proactive and flexible in a fast-moving environment
- Problem solving and independent research skills
Desirable Skills:
- Compression fittings (Swagelok, Schwer) or general pipework
- Able to read P&IDs and GA drawings
- Pressurised gas or liquid systems
- DAQ or programming (LabVIEW, Python)
- Hazardous fluid handling or ATEX awareness
- CAD (SolidWorks, Fusion 360, Onshape, or similar)
- Interest in hydrogen, fuel cells, or clean energy
- Full UK driving licence
Your profile: You’re practical, curious, and want to build things. Maybe a recent graduate who spent more time in the workshop than the lecture hall, or a technician looking to move into R&D. You don’t need to know anything about electrolysers — we’ll teach you. What matters is that you pick up a tool before being asked and take ownership of what lands on your bench.
Why us? Broad hands-on experience across mechanical build, instrumentation, and test engineering. Experienced engineers who will invest in your development. A genuine foot in the door of the UK hydrogen industry. Small team where you see the impact of your work immediately. 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.
