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 a Senior Operations and Test Engineer at Hermeus, you will help develop, test, and operate advanced aircraft systems through hands-on integration, checkout, development testing, and taxi test campaigns. This role blends engineering, operations, and automation, with a focus on building standardized processes and tools that make vehicle testing safer, faster, and more repeatable. You will work closely with technicians, specialists, and cross-functional engineering teams to support hardware integration, troubleshoot off-nominal results, improve test readiness, and turn lessons learned into better procedures, equipment, and workflows. This is a fast-paced, hands-on role for someone who is comfortable working around complex and hazardous systems, enjoys solving problems in real time, and can help drive reliable operations in a rapid hardware development environment.
