Generalist Engineer — Secret Project

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
