Careers

Work on the hard part.

Most propulsion jobs iterate on solved problems. Ours don't: printed ceramics at 2,700 K, high-power density packed-bed thermal-hydraulics, compact reactor dynamics coupled to turbomachinery. Small team, direct access to the founders, and what you do shows up in hardware decisions the same week.

Openings are posted as they arise. U.S. persons only for most roles (ITAR). Send a résumé and, more importantly, something you've built or analyzed to careers@darkfission.space.
