Long Beach, US · Full-time · $184,500 – $225,500

About this role

At Relativity Space, we’re building rockets like Terran R to deliver customer payloads to orbit and unlock opportunities in science and exploration. As Principal Turbomachinery Engineer, you will develop assemblies for the fuel and oxidizer turbopumps of the Aeon-R engine family. You'll collaborate closely with propulsion development and manufacturing teams.

You'll thrive in ambiguity, driving your own projects to completion while working through challenging issues unique to rocket turbopumps. Work at the interfaces of design, development, and analysis of turbomachinery. Incorporate improvements into future designs based on testing and iteration.

The propulsion team owns engine design from concept through launch and reuse, partnering with manufacturing, test, launch, and integration teams. Develop Aeon-R engine systems in record time to support Terran R's first launch in 2026. See your work mature and bring Terran R into space.

Relativity offers autonomy, ownership, and impact at every level, where creativity and technical rigor go hand in hand. Shape decisions across teams in propulsion, manufacturing, and more. This is your chance for the most meaningful work of your career.
