Integration Engineer – Fluid & Propulsion Systems

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. We are seeking an Integration Engineer to own the design release, build, test, and delivery of key vehicle fluid, propulsion, and mechanism assemblies — including control surface actuators, spike inlet systems, engine integration, and other mission-critical hardware.    You will serve as the technical bridge between design, manufacturing, and test, ensuring our hardware is built with precision, efficiency, and reliability. This role requires a hands-on engineer with a strong background in mechanical systems, propulsion, and fluids — capable of driving complex assemblies from concept through validation in a fast-paced, first-principles environment.
