Senior Launch Fluids Engineer

Overview 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 solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Collaborating across teams, shaping decisions, and seeing your work come to life in record time. About the Team The Launch team operates at the intersection of every major aspect of Terran R, from stages and payloads to ground systems, launch, landing, and refurbishment. The Cape is the only place where you see it all come together, offering exposure and responsibility unmatched elsewhere. If you’re looking to define what’s next in space launch and write a new playbook, this is where it happens.
