F100 MRO

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 Role

As an MRO Propulsion Engineer you will take ownership of the maintenance, refurbishment, and overhaul (MRO) lifecycle of our F100 engines—including acceptance testing. This is a hands-on, high-impact role where you’ll work side-by-side with passionate engineers and technicians to keep our propulsion systems performing at their best. If you want to learn fast, solve hard problems, and contribute directly to hypersonic capability, this is the place for you.
