This full-time Senior Engineer role at Ursa Major focuses on the design, integration, and execution of propulsion systems for hypersonic vehicles and defense applications. The position sits at the intersection of propulsion design, systems engineering, and testing, requiring ownership from early concept through flight demonstration. Key responsibilities include leading propulsion subsystem architecture, performing clean-sheet design of fluid and mechanical components, and managing verification plans and technical trades. The role offers the appeal of working on critical national security missions within a fast-paced, hardware-centric culture that values rapid development and technical ownership. Engineers will collaborate closely with cross-functional teams to resolve design challenges and mentor junior staff. The position is based in Berthoud, Colorado, with a hybrid work arrangement allowing two days of remote work per week.
