Rotterdam, Netherlands Full-time On-site
Help build the electrical core of a new electrolyzer that can make green hydrogen cheaper.
We’re hiring an Electrical Engineer to work on Spiral Hydrogen’s integrated generator-electrolyzer: a system where the electrical machine and electrolyzer are designed together.
This is a hands-on R&D role for someone who enjoys moving between simulation, bench experiments and real hardware.
About Spiral Hydrogen
We’re building a new type of electrolyzer to make green hydrogen cheap.
Today, many industries, including fertilizers, chemicals and refining, rely on hydrogen made from natural gas. This creates emissions, dependence on imported fuel and exposure to volatile energy prices. Many of these industries would prefer to switch to local green hydrogen, yet the cost gap remains too high.
We recently validated a technology that can significantly lower the cost of green hydrogen. Now we’re building a pilot version in Rotterdam, at the heart of one of Europe’s most important industrial regions.
The role
As our Electrical Engineer, you’ll help design, build and test the electrical system inside Spiral’s generator-integrated electrolyzer.
The most important questions you will work on are:
- how generator geometry, electromagnetic design and electrolyzer load behavior interact
- how to define operating points across speed, torque, voltage, current, losses, temperature and hydrogen production
In addition, you will tackle the following issues:
- how to rectify and deliver high-current DC power into electrolysis
- how to instrument, protect and control experimental hardware
- how to use test benches to simulate variable shaft power and changing operating conditions
- how to turn experimental data into better prototypes and design decisions
You should be comfortable designing experiments, building test setups, debugging measurements and working directly with hardware.
You might be a fit if
You may be a strong fit if you have solid electrical engineering fundamentals and enjoy applying them to real systems.
We’re interested in people with strong expertise in:
- rotating electrical machines, motors, generators or drives
Additionally, knowledge of these fields will improve your candidacy:
- electromagnetic design or machine testing
- rectifiers, power electronics or high-current DC systems
- sensors, instrumentation, data acquisition or controls
- wiring, schematics, protection and practical lab setup
- variable renewable power, turbines, electrolysis, fuel cells or other energy hardware
Hydrogen experience is welcome, although it is not required. We care more about evidence that you can understand complex electrical systems, build useful experiments and make good engineering decisions from real data.
You should enjoy unclear technical problems, hands-on work and close collaboration with mechanical and electrochemical engineers.
