Propulsion Manufacturing Engineer II, Combustion Devices

Relativity Space•Long Beach, CA

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’ll 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 Engine Manufacturing team is dedicated to delivering high-performance engines and advancing innovative manufacturing systems that continuously improve cost, quality, and lead time. You’ll actively provide input that shapes new hardware iterations and regularly interface with engineers to make critical decisions for the Aeon R program. Having successfully developed and refined processes for our initial development engines, the team is now focused on producing flight engines at rate for Terran R’s aggressive launch manifest. This role will oversee the end-to-end manufacturing for the development and production of Combustion Device (fire-breathing) hardware for Aeon-R and Vacuum Engine programs. You will develop initial processes required to build the hardware, implement into production, and drive process improvements to enable rapid production ramp. You will closely collaborate with stakeholders within (machine shop, additive, etc.) and external to Manufacturing (Supply Chain, Propulsion Design, etc.) to drive manufacturability and scalability in your hardware. You will ensure delivery to engine to meet program targets, as well as drive continuous improvement, new product development, and strategy for Combustion Device manufacturing at Relativity as a whole.
