Systems Engineering Analysis, Senior

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.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. 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. About the Role: As a Vehicle Fluid Systems Engineer, you will be responsible for the fluid system architecture and function for a given vehicle fluid subsystem. You will apply expertise in system architecture, systems operations, and fluid thermodynamics applications to guide hardware design, system analysis, manufacturing, validation and operations. • Own the vehicle fluid subsystem architecture and schematics, including system control scheme, system and component selection and sizing • Conducting fluid and thermal analyses, including system sizing and characterization using a variety of base analytical methods (1D steady-state, fluid networks, etc.) • Leading and participating in system and hardware design and manufacturing reviews • Defining and supporting test objectives and test campaigns to validate system design, system models and overall system performance including supporting integrated vehicle testing and launchAbout You: • Bachelor’s degree (Mechanical Engineering or relevant) • 4+ years of experience working with fluids systems • Experience applying engineering fundamentals in system design, thermodynamics, fluid dynamics, and heat transfer • Experience with one or more fluid or thermal modeling tools for internal compressible and incompressible analysis • Proficiency in Python or a similar programing language for scientific computing and automated test/simulation data analysisNice to haves, but not required: • Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more!
