Role summary
Relativity Space is seeking a Fluids Analyst II, Combustion Devices to join their Propulsion team. This role involves contributing to the design and qualification of combustion device hardware through Computational Fluid Dynamics (CFD) analysis. You will review test and flight data, interface with hardware designers, and leverage thermofluid expertise to influence design decisions. The ideal candidate has a Bachelor's degree in science or engineering, 2+ years of CFD analysis experience, familiarity with analysis steps, and scripting skills in Python, MATLAB, or similar. A strong background in fluid mechanics and heat transfer is required. Experience in aerospace, a graduate degree, Siemens STAR-CCM+, and knowledge of rocket engine subsystems are considered nice to have.
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 Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.
