Vehicle Fluids Engineer Intern

At Relativity Space,we’rebuilding 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. Butthat’sjust 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'renot just executing tasks;you'resolving problems thathaven’tbeen solved before, helping develop a rocket, a factory, and a business from the ground up. Whetheryou’rein propulsion, manufacturing, software, avionics, or a corporate function,you’llcollaborate 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 storieswe’rewriting together. Now is a unique moment in timewhereit’searly 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 TheStage Fluidsteam designs and deliversthe propellant,pressurant, pneumatics, and other fluid systems that turn structures into functioning rockets. The team has full ownership across design, production, test, and flight,maintaininga holistic view of Terran R, focused not on isolated parts but integrated functionality. Working on-site at the factory meansyou’renever far from the hardware, enabling rapid iteration and tight feedback loops across design and manufacturing. Youwon’tjust behandedrequirements:you’llbe expected to ask the right questions, collaborate with partners across the company, andultimately findthe best solutions for Terran R. About the Role In this role, you will support for the mechanical and systems-level design and analysis for the stage fluid systems, ensuring a reliable and efficient operation of our Terran R launch vehicle, including: Structural design of secondary structures supporting fluids hardware Mechanical design validationutilizingFEA and/or hand calcs Tube routing design and analysis Fluids system analysis utilizing 1D Flow solvers and hand calcs About You Current undergraduate or graduate student in mechanical or aerospace engineering or equivalent Project or industry experience with a commercial CAD package (NX,Solidworks, etc...)
