Integration Engineer – Fluid & Propulsion Systems

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. 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.
