The future of aerospace and defense starts here.
Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands.
Ursa Major is seeking a Propulsion Engineer II (propulsion systems) to support the technical definition, integration, and execution of propulsion systems for hypersonic vehicles.
Ursa Major’s teams move fast and does a lot with little. We are looking for a skilled, fast-learning individual who will serve as a central member of the team and take immediate ownership of their system as a responsible engineer. This role sits at the intersection of propulsion design, vehicle integration, systems engineering, and test, with ownership from early concept through flight demonstration and production transition.
The ideal candidate brings propulsion experience, strong systems thinking, and the ability to drive technical decisions in fast-paced, hardware-centric programs.
Key Responsibilities
Clean sheet design and analysis of fluid mechanical vehicle components including tanks, structures, feed systems, propellant management, and fluid systems
Leverage first-principles engineering to drive design and technical decisions
Support rapid development cycles of new designs and changing requirements including testing, data analysis and hands-on hardware work
Design modifications of existing components and prototypes to increase performance, improve manufacturability or resolve limitations
Support test planning and execution, including ground and flight test support
Participate in failure investigations, nonconformance resolution, and continuous design improvement
Assembly and testing of first article prototypes
Collaborate with the manufacturing, analysis, and test teams to reduce part-to-part variation and discrepancies
Work with other engineers at Ursa Major on topics including design of components, system sizing, component testing, and system-level architecture.
Interface with customers and external partners during design reviews, technical interchange meetings (TIMs), and integrated product team (IPT) meetings
Support manufacturing through design for manufacturability (DFM) and producibility considerations
