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 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 flexibility 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.

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.
