Electrical Engineer (Generator + Control)

Rotterdam, Netherlands • Full-time • On-site

Spiral Hydrogen is building a wind-to-hydrogen system where the generator and electrolyzer are designed as one integrated machine.

Instead of sending wind power through the grid before it reaches an electrolyzer, we are developing a custom generator, rectification and control setup that delivers controlled DC directly into our electrolyzer.

Your job is to help turn variable mechanical rotation into stable electrical input for hydrogen production.

What you will do

You will design, build and test the electrical system inside our generator-integrated electrolyzer.

This means working on generator behavior, rectification, current delivery, controls, protection and test-bench validation.

You should be comfortable with hands-on R&D: building setups, debugging measurements, running tests and using data to improve the next design.

You might be a fit if

You have strong electrical engineering fundamentals and experience with generators, power electronics, or controls. This usually includes:

A relevant Master's degree (electrical engineering, physics, or mechanical engineering)
2+ years industry experience in building or maintaining generators, power electronics systems, control systems, rotating equipment or electrolyzer interfaces.
Experience in an agile, iterative, startup-like environment; or otherwise experience building and testing prototypes.
Personal projects that lets us see you like building things!

Hydrogen experience is useful, but not required. We care more about whether you can understand complex hardware, test it properly and make good engineering decisions.
