Where: Long Beach, California
Posted: May 21

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.

Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll collaborate across teams, shape decisions, and see your work come to life in record time.

What you'd do

Develop manufacturing processes, new techniques, and tools to enable high rate productions and increase engine performance
Work hand-in-hand with the design and analysis teams to simplify our propulsion systems
Participate in design reviews and lead design for manufacturing (DFM) initiatives
Design test set-ups, coordinate and execute development, qualification, and acceptance testing of systems, and conduct data reviews
Participate in test failure investigations and implement corrective actions
Design, analyze, and procure tooling for piece part manufacturing and system testing
Create and maintain development build and test schedules

About Relativity Space · G-Components Engineering

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.
