Hermeus is a aircraft manufacturer focused on rapid design, build, and test of high-Mach and hypersonic aircraft.
The Role
Supports development of flight-critical propulsion components such as valves, actuators, and fluid-control hardware from clean-sheet design through production. Responsibilities include engineering trade studies, analysis, integration, build-test-iterate cycles, troubleshooting, root-cause analysis, qualification, reliability and safety evaluation, and transition to production-ready designs. The intern collaborates with propulsion and vehicle teams in hands-on, fast-paced build and test environments.
Summary Generated by Built In
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.

What We Do

Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. 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. Today, Hermeus is building its second Quarterhorse vehicle, Mk 2, after having designed, built, and flight tested its predecessor, Mk 1, in 18 months. Capable of reaching speeds of Mach 3+, Quarterhorse Mk 2 will be the fastest uncrewed military aircraft in service for national defense. The final iteration of Quarterhorse, Mk 4, will be capable of transitioning from turbofan to ramjet mode utilizing a Hermeus-developed turbine-based combined cycle (TBCC) propulsion system to achieve sustained speeds of Mach 5+. Hermeus' approach of build-fly-build lays the groundwork for unlocking hypersonic flight at a pace and cost previously deemed impossible. America needs fast planes fast – and Hermeus is delivering them.

Why Work With Us

We prioritize hardware and people. Cutting-edge technology is only made possible by bringing together a world-class team. At Hermeus, you will be challenged – but also empowered. We encourage calculated risks taking and learning from our mistakes. Iteration is the name of the game.
