Responsibilities

Propulsion Hardware Development Engineers are responsible for taking the Aeon-R engine from paper designs to highly reliable, high-performance hardware.

This role requires deep engagement with both the design and production teams to ensure our designs are readily manufacturable and our manufacturing processes are reliable and production-ready.

You will also be responsible for developing new manufacturing processes to improve Aeon-R engines and the Terran-R vehicle.

You should have strong engineering fundamentals as well as a knowledge of aerospace manufacturing techniques to be an effective Hardware Development Engineer.

The role demands close interaction with propulsion hardware, including defining build procedures and hands-on build and integration of hardware.

Develop manufacturing processes, new techniques, and tools to enable high rate productions and increase engine performance

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.
