Job description

About the Team: 

The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.

About the role: 

As a Responsible Engineer, you'll have cradle-to-grave ownership of your assigned component, from initial design through manufacturing, testing, qualification, and flight. This level of end-to-end ownership over combustion hardware is rare in the aerospace industry, where these responsibilities are typically distributed across multiple teams and organizations. Combustion devices are among the most thermally and structurally critical components in the engine, operating under extreme temperatures and pressures. The RE role provides technical ownership at the component level, requiring coordination across disciplines and direct accountability for hardware decisions throughout the entire product lifecycle. 

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
