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:
As lead, you will lead a small team of vehicle fluid hardware engineers. Your scope will be focused on hardware ownership throughout the evolution of the program. Packaging, detailed design of large numbers of parts, broad design process improvement and implementation, hardware integration support and supporting vehicle hardware as it moves with the vehicle will all fall within your responsibility. Designs and packaging trades will be informed by both fluid and structural analytical and computational models. You will own the long-term iteration/trajectory of the vehicle fluids hardware and iterate to reduce the cost, complexity and weight of TerranR fluids. You and your team will need to operate on tight timelines, on a scope spanning 1000s of parts while clarifying ambiguity and improving organization.
About You:
- Bachelor’s degree in science, engineering, technology, or mathematics field
- 3+ years of experience with fluid systems design and/or structural design
- Experience in mentoring and demonstrated leadership skills
- Experience with computer-aided design software
- Experience with Finite Element analysis (FEA) and commercial tools
- Fundamental understanding of fluid, structural, and mechanical design fundamentals
- Ability to drive to deliver on ambitious schedules
Nice to haves but not required:
- Experience leading teams
- Experience in the design and analysis of fluid components and systems
- Experience with Siemens NX, Teamcenter, and ANSYS specifically
- Experience with large CAD model management, change management and configuration management
- Experience supporting hardware build execution
