Propulsion Design Engineer II, Combustion Devices

About the Team: 

The Propulsion team at Relativity is responsible for the successful development of the engines that will power the Terran R vehicle. We own their design from concept through to launch and reuse. Our team partners heavily with Manufacturing, Test, Launch, and Integration teams, striving to develop our engines in record time and to support Terran R's first launch in 2026. As part of this team, you will help build, test, and iterate on the full product lifecycle of our Aeon-R engine systems, seeing them mature and eventually bring Terran R into space.

About the Role: 

You will own propulsion combustion devices and/or systems from concept through manufacturing and implementation. This role involves a range of skillsets: design, analysis (structural, thermal, fluid), manufacturing, test, project management, and communication. You will work across teams and departments and take ownership of projects of your creation. In order to be successful in this role, you should be someone who thrives in ambiguity and be capable of leading collaborative projects to completion with minimal oversight. Along with these high expectations comes the opportunity to have a significant influence on a fast-growing startup company and to make rapid professional gains in an environment that encourages growth and risk.

About You:  

• Bachelor's degree in a science or engineering field
• 2+ years of experience working in the development of propulsion components, combustion components, or related hardware
• Experience applying engineering fundamentals in thermodynamics, thermal, structural, and fluids

Nice to haves but not required:  

• Experience in a rocket engine development and/or test environment
• Clear evidence of ownership from school or work experience
• Working knowledge of engine subsystems such as combustion devices, heat exchangers, ducting
• Exposure to powder bed additive manufacturing and automation techniques
