Generalist Engineer — Secret Projects

Delft and Rotterdam, Netherlands • Full-time/Internship • On-site

The Purpose

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

If this sounds exciting, let’s talk!

Note: Due to a large number of applicants we may not be able to respond to everyone. If you haven’t heard back from us in three weeks, please assume we have moved forward with other candidates. Thank you for your interest!
