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’s teams move fast and do 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 fluid and mechanical system design efforts as a responsible engineer. This role will be part of the technical organization, responsible for clean sheet design, development, and validation of a variety of propulsion hardware, as well as technical guidance and mentoring of a team responsible for similar hardware. Candidates will be expected to have ownership from the initial concept phase to a production-ready design.
Responsibilities:
- Clean sheet design of fluid & mechanical engine components including gimbals, actuators, valves, and fluid systems
- Design modifications of existing components and prototypes to increase performance, improve manufacturability or resolve limitations
- Work with other engineers at Ursa Major on topics including design of components, system sizing, component testing, and system-level architecture and development
- Derive requirements from top level engine and test objectives
- Write, review, and update work instructions for the assembly of engine components as well as establish appropriate acceptance and qualification tests
- Assemble and test first article prototypes
- Work closely with interfacing teams to ensure successful integration of component designs into the engine system
- Support validation and recursive design during engine development
Required Qualifications
- Bachelor’s degree in engineering
- 4+ years of relevant mechanical design experience
- Electromechanical and pneumatic actuator design experience
- Experience testing high-pressure fluid systems
- Demonstrated proficiency with computer aided design and drafting
- Experience with geometric dimensioning and tolerancing per ASME Y14.5
- Strong understanding of industry standards and requirements
- Desire to take ownership and help wherever needed on the team
- Able to delegate tasks and lead large project scope
- Ability to work in a fast-paced environment and stay flexible based on customer demands and company priorities along with daily firefighting
