Propulsion Engineer I - Hardware Development

Propulsion Hardware Development Engineers take the Aeon-R engine from paper designs to highly reliable, high-performance hardware. The role requires deep engagement with design and production teams to ensure designs are readily manufacturable. Manufacturing processes must be reliable and production-ready while developing new techniques for Aeon-R engines.

Daily work includes developing manufacturing processes, new techniques, and tools that enable high-rate production and higher engine performance. You work hand-in-hand with design and analysis teams to simplify propulsion systems and participate in design reviews to lead design-for-manufacturing initiatives.

The Propulsion team owns the full lifecycle of Aeon-R engines for Terran R, from initial design through production, qualification, and flight. Engineers operate in a bottoms-up culture that values ownership and accountability at every level without technical gatekeeping.

Relativity offers the chance to solve problems that have not been solved before while building a rocket, factory, and business from the ground up. It is early enough to shape the product, process, and culture yet far enough along that Terran R is tangible and accelerating.
