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.
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.
The salary range listed for this role is intended as a general guideline. Final compensation will be determined based on a variety of factors, including role scope and responsibilities, relevant experience, education and training, key skills, market data, and business needs.
At Hermeus, compensation is only one part of our total rewards package. We offer competitive pay, equity, and a range of benefits designed to support our team.

Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries.
Utilizing an integrated, hardware-rich, iterative development approach to aircraft design and build, Hermeus aims to deliver advanced air power at a pace not seen in the U.S. since the 1950s. Hermeus’ current Quarterhorse Program is actively unlocking unmanned high-speed flight. One program, four aircraft – each purpose-built to unlock a specific technical challenge, advance learnings, and incrementally de-risk critical technology in the pursuit of hypersonic aircraft.
America needs fast planes fast – and Hermeus is delivering them.
