Senior Mechanical Engineer
Manufacturing and Production Development
Rotterdam • Full-time • On-site
Spiral Hydrogen is building a new kind of electrolyzer. One that doesn’t produce bubbles and achieves 90% efficiency (compared to 60–70%). Our goal is to produce green hydrogen cheap enough to compete with fossil-based hydrogen, allowing a 200B€ industry to decarbonize.
What you’ll own
The goal is to take our rotating bubble-free alkaline electrolyzer from first prototypes (TRL 4) to 10–100 kW pilots (TRL 6–7) and beyond.
You’ll join 2 other mechanical engineers (in a total team of 10) to work on the mechanical and manufacturing aspects: sealing, wobbling, liquid and gas channels, as well as design for manufacturing.
The ideal candidate is able to build thousands of cells that are exactly the same, down to the micron. And do it in a new, unique architecture.
What you’ll need
Must-haves for the candidate:
5+ years hands-on experience building new products, prototypes, testing, metrology. Ideally in an agile startup environment.
5+ years with production and manufacturing processes. If we need to build 300 000 identical electrolytic cells with micron precision, this should be something in your wheelhouse. Experience with design for manufacturing, injection molding, assembly lines, New Product Introduction is useful.
Nice-to-haves:
Experience with hydrogen systems, fuel cells, etc.
Experience operating in corrosive environments.
Experience with rotating machinery, maintenance, stability.
Experience with materials engineering.
What we offer
High ownership role in a mission-driven small-team environment.
Competitive salary, and options package
Practicalities
Full-time on-site role in Rotterdam, Netherlands
Process: 2–3 interview rounds, 1 test task
Visa sponsorship for exceptional candidates
