Senior Manufacturing Engineer, Integrated Components

Relativity Space•Long Beach, CA

13d•$122,000 - $182,000•Onsite

About The Position

Relativity Space is building rockets to serve today’s needs and tomorrow’s breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. 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. You will be solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. You’ll collaborate across teams, shape decisions, and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand, and your voice will help define the stories we’re writing together. This is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The Propulsion Manufacturing Integrated Components team manufactures and tests critical Aeon-R engine components including manifolds, gimbal assemblies, brackets, orifices, etc. The team ensures on-time delivery of propulsion subassemblies to the Aeon-R engine program while driving continuous improvements in safety, quality, reliability, lead time, and cost. After successfully delivering hardware and developing processes for the first Aeon-R flight engines, we're entering a critical phase: ramping production while concurrently developing next-generation engines to make Terran R the most manufacturable high-performing rocket to date. This role requires a high degree of autonomy and initiative to provide design feedback, pioneer advanced manufacturing methods, and deliver flight hardware for integration and testing.
