Job Description
Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

About the Team:  

You'll join a small, fast-moving team building the avionics and flight software for a new flight vehicle program from clean sheet. Everything is actively being built, integrated, and tested on real hardware supporting real tests.

This role will focus on developing simulation and hardware-in-the-loop (HITL) infrastructure, combining software development, flight simulation, and hands-on hardware integration.

Small team, big ownership, and we move at speeds the rest of the industry doesn't.
