About The Company

Relativity Space is on a mission to make access to space more reliable and routine. Our medium-to-heavy lift reusable rocket, Terran R, 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.

About the Role

<div class="content-intro">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.</div>About the Team:  The engine manufacturing department's mission is to product high performing products & manufacturing systems by continuously innovating on cost, quality, and lead time. Through cross-functional collaboration, high levels of accountability, and a focus on safety we support the Terran R program. We are responsible for providing design feedback on new hardware iterations, developing new manufacturing methods and systems, and ultimately building engine and vehicle hardware for testing prior to our first launch. Our team's highlights from the last 6 months include the MDC of the first Aeon-R engine, completing thousands of hours of PBF printing, building and testing over 50 valves of 26 different iterations, and implementing large scale process improvements along the way.  About the Role: As a Propulsion Technician, you will be on the front line of the assembly and testing of the Aeon-R engine components, sub-assemblies and engines. This is a unique opportunity to be a part of an experienced technical team and build the skills necessary to create and refine robust component and engine building processes. This role will be focused on supporting several in-house processes and support resources such as precision cleaning, hydrostatic proof testing, flow testing, component assembly and test, and engine assembly.   About You: <ul> <li style="font-family: arial, helvetica, sans-serif;
