Generalist Engineer — Secret Project

Rotterdam, Netherlands • Full-time • On-site

We are always interested in exceptional people.

Sometimes the right person does not fit neatly into a job description. Sometimes we meet someone unusually sharp, agentic, technical, creative, or obsessive, and it becomes obvious that we should find a way to work together.

This page is for those people.

We are building a new kind of hydrogen hardware company. Most of our work is public enough to explain: cheap green hydrogen, rotating electrolyzers. Some of the more interesting problems are still early, messy, or confidential.

We do not promise that there is a perfect open role today. But if you are exceptional, we want to know you.

What we’re looking for

Strong candidates usually have:

Unusual agency: you make things happen without needing much structure.
Very fast learning speed.
Strong technical taste and first-principles reasoning.
Evidence of building, fixing, designing, testing, or otherwise making real things happen.
Comfort with ambiguity and early-stage problems.

These are strong pluses, not strict requirements:

You have built impressive projects outside school or work.
You have worked in startups, labs, competitions, student teams, open-source projects, research groups, or unusual technical environments.
You can cross domains: hardware, software, electronics, materials, chemistry, manufacturing, or whatever the problem needs.
You have won things, shipped things, broken things, repaired things, or learned your way into a hard field.
People who know you would describe you as unusually intense, curious, useful, or hard to replace.

Practicalities

Location: On-site in Delft, Netherlands (office + workshop at YES!Delft) and Rotterdam (in the future).
Time commitment: Full-time / Internship options can be considered
Team: Small, technical, founder-led
Compensation: Competitive salary + equity for early employees
Start: As soon as possible
