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. 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 Stage Fluids team designs and delivers the propellant, pressurant, pneumatics, and other fluid systems that turn structures into functioning rockets. The team has full ownership across design, production, test, and flight, maintaining a holistic view of Terran R, focused not on isolated parts but integrated functionality. Working on-site at the factory means you’re never far from the hardware, enabling rapid iteration and tight feedback loops across design and manufacturing. You won’t just be handed requirements: you’ll be expected to ask the right questions, collaborate with partners across the company, and ultimately find the best solutions for Terran R. About the Role: In this role you will be responsible for the design, analysis, development and qualification of flow control devices for the Aeon R engine and Terran R launch vehicle. Specific responsibilities will include: • Design and analysis of clean sheet of cryogenic, pneumatic, proportional, or solenoid valves • Detailed fluid, thermal, and structural analysis of piece parts and assemblies • Development and qualification test planning and execution of internally developed valves • Engine and vehicle test support for existing flow control products • Conducting trade studies to produce architectures and designs that satisfy system requirements About You: • Bachelor’s degree in relevant engineering discipline (Mechanical or related) • 5+ years of professional engineering experience • Direct experience applying engineering fundamentals in thermodynamics, structures, fluid dynamics, and heat transfer • Experience with programming languages such as Matlab, Python, or C++ • Experience with CFD and FEA tools (ANSYS) At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors. Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more!
