Propulsion Engineer (Vehicle)

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 I (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.

Required Qualifications

Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related field 1-3 years of experience in propulsion systems engineering or propulsion-focused vehicle development. Candidates with strong internship or project/academic club experience in related field are encouraged to apply. S.

Preferred Qualifications

Master’s degree in Aerospace Engineering or related field Desire to take ownership of multiple projects at once 1+ years of Siemens NX CAD programs and Windchill PLM software Experience leading design reviews to communicate design decisions and trades.
