Careers
Build things that don't exist yet, with people who love the hard problems
Work at Fehr GmbH
We take on projects most companies turn down: reverse engineering decades-old systems, breaking and hardening hardware, and building software and devices from the first concept through to production. If you like depth over buzzwords and ownership over process, you will feel at home here.
