Engine Systems Design & Analysis Team- Staff Propulsion Design Engineer

Job Description 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. 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. Hiring Manager:

Ty Teodori About the Team: The Propulsion team at Relativity is responsible for the successful development of the engines that will power the Terran R vehicle. We own their design from concept through to launch and reuse. Our team partners heavily with Manufacturing, Test, Launch, and Integration teams, striving to develop our engines in record time and to support Terran R's first launch in 2026. As part of this team, you will help build, test, and iterate on the full product lifecycle of our Aeon-R engine systems, seeing them mature and eventually bring Terran R into space. About the Role: You will be responsible for the overall layout, design, analysis, and build of hardware for our Aeon-R propulsion systems. You will work closely with other propulsion teams, the vehicle team, manufacturing/integration teams, and test teams to design, analyze, and optimize. Designs will be informed by fluid and structural analytical and computational models. Engine assembly level layouts and trades will be weighed against weight, cost, lead time, and part count. To be successful in this role, you should thrive in ambiguity and be able to lead your projects to completion. About You: 8+ years of professional design experience Bachelor's degree in an engineering field Experience with computer-aided design (CAD) software Experience with mechanical design Experience applying fluid, thermal, and structural fundamentals Experience with Finite Element Analysis (FEA) and tools such as Ansys, Abaqus, or Nastran Experience managing large CAD models, change management, and configuration management Nice to haves, but not required: Experience with Siemens NX and Teamcenter Experience in designing liquid propulsion components and systems Familiarity with aerospace standards (AS, NAS, SAE, etc.) At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be based on experience, qualifications, and other factors.
