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 lead a team of engineers working on valves and accompanying systems through design, development, testing, and production. This role involves a range of skillsets: design, analysis (thermodynamics, structures, fluids, electrical), manufacturing, test, project management, communication, and leadership. You will work across teams and departments and take ownership of projects of your creation. To be successful in this role, you should be someone who thrives in ambiguity and be capable of leading highly technical and collaborative projects to completion with minimal oversight. Along with these high expectations, this position will involve recruiting, career development, and mentoring engineers.

About You:

• Bachelor's degree in an engineering field

• 5+ years of experience in fluid control devices, valves and/or mechanisms design and analysis

• Proven leadership experience, demonstrated through mentoring, managing complex interdisciplinary projects, supporting continuous improvement of the people around you or participating in growing your team through hiring

• Experience applying engineering fundamentals in thermodynamics, structures, and fluids

• Hands-on experience with fluids and structural development testing and manufacturing

• Experience with ownership of projects from school or work experience

• Experience leading projects or small teams

Nice to haves but not required:

• 5+ years relevant experience, preferably in a rocket engine development and/or test environment

• Experience with the design and manufacturing process of valves, regulators, and actuators, motors, solenoids

• Experience with design and testing of cryogenic systems and components

• Exposure and knowledge in powder bed additive manufacturing

• We believe varied perspectives & backgrounds strengthen our team. Prior experience in aerospace is not required
