About The Position

At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. 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. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, 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. Now 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 most meaningful work of your career is waiting. Join us. About the Team: The LP-DED team is a new team at Relativity dedicated to implementing and productionizing LP-DED for S1 Skirt for Aeon-R. This team will take this metal powder based additive process from initial prints on the factory floor and building out the production work center, all the way to fully-optimized, high-rate production to support our ramp goals. We will strive to not only hit our S1 skirt production targets, but also to bring new applications of the technology to the vehicle as well! About the Role: Drive implementation of LP-DED Additive into production, enabling a rapid ramp-rate for Aeon-R production. Develop, validate, and optimize operations, processes, and the LP-DED workcenter to enable reliable at-rate production while maintaining quality, cost, and safety targets. Drive projects for improvement of process efficiency/throughput for LP-DED. Define and deploy process controls, standard work, and documentation that scale with increasing production demand. Develop procedures for deposition operations, calibration, preventative maintenance, etc. Lead troubleshooting and root-cause investigations on first-time and recurring issues, implementing sustainable corrective actions.
