Relativity Space is building rockets to serve today's needs and tomorrow's breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting growing demand for launch capacity. The company is developing a rocket, factory, and business from the ground up, with a culture emphasizing autonomy, ownership, and impact at every level.
The Stage Fluids team designs and delivers propellant, pressurant, pneumatics, and other fluid systems that turn structures into functioning rockets. The team maintains full ownership across design, production, test, and flight, with a holistic view of Terran R focused on integrated functionality rather than isolated parts. Work is on-site at the factory, enabling rapid iteration and tight feedback loops between design and manufacturing.
In this role, you will be responsible for the mechanical and structural implementation of stage fluid systems, ensuring reliable and efficient operation of the Terran R launch vehicle. Key responsibilities include:
- Fluids routing and design trade studies
- Fluids hardware mounting structure design
- Fluid system hardware mechanical verification analysis using hand calculations and FEA
- Structural design of mounting hardware for various fluid system components and routing
- Incorporating 3D printing methods into fluid system mechanical design
- Design for Manufacturing (DFM) and Design for Assembly (DFA)
You will have end-to-end ownership of your designs and will see hardware you designed come to fruition rapidly. The role requires someone who enjoys leading the way for the team on exploring new methods and design approaches, is flexible to changes in strategic direction, and takes full ownership of projects to ensure the company produces the best possible product while incorporating innovative production methods.
REQUIREMENTS:
- Bachelor's degree in mechanical engineering or equivalent engineering discipline
- 2+ years of mechanical design experience
- Experience with commercial CAD packages (NX, CREO, Solidworks)
- Experience with GD&T, manufacturing, and vendor interaction
- Experience with fluid system components (fittings, seals, valves, regulators, etc.) and system testing
- Experience with FEA tools to analyze structural margins
