Note: This is a hands-on engineering role to help us build our 10 kW pilot and the 100 kW system that follows. We are looking for someone strong in CAD, procurement, prototyping, assembly, testing, and materials choices. Experience with rotating systems is a plus.
The Purpose
We’re building a new kind of electrolyzer to make green hydrogen cheaper than grey hydrogen.
Spiral Hydrogen has validated the core design, protected the IP, and raised VC funding. Now we’re building our 10 kW pilot, followed by a 100 kW system.
We’re looking for a hands-on electrical engineer who can help turn ambitious ideas into working hardware.
What you'll do
You’ll work directly with the founders and technical team on the electrical systems behind our pilots and test setups.
In practice, you will
Design, build, and improve electrical systems for prototypes, test rigs, and pilots.
Work on motors, generators, drives, power electronics, sensors, wiring, controls, and data acquisition.
Help specify and procure components.
Assemble, test, debug, and improve hardware in the lab and workshop.
Work closely with mechanical and electrochemical engineers.
Solve new problems where the right answer is not obvious yet.
This is not a desk-only role. We need someone who enjoys building, testing, breaking, fixing, and learning fast.
What we’re looking for
Strong candidates usually have:
A few years of relevant industry experience.
Broad electrical engineering knowledge.
Strong hands-on experience with real hardware.
Comfort with CAD, wiring diagrams, schematics, and practical system design.
Experience with motors, generators, drives, power systems, sensors, or test equipment.
High agency: when something is unclear, you find the next useful step.
Initiative, speed, and clear communication.
Genuine curiosity for how things work — ideally from years of building, fixing, or experimenting.
These are strong pluses, not strict requirements:
Experience with rotating electrical machines.
Experience moving from lab prototypes to larger industrial systems.
Practicalities
Location: On-site in Delft, Netherlands (office + workshop at YES!Delft) and Rotterdam (in the future).
Time commitment: Full-time
Team: Small, technical, founder-led
Compensation: Competitive salary + equity for early employees
Start: As soon as possible
If you want to build serious hardware for a huge energy problem, we’d love to talk.
