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 and Components team is responsible for all fluid systems and components on the Terran R launch vehicle. This includes systems for the liquid oxygen and liquid natural gas propellants as well as the supporting helium and nitrogen gasses. We also design the individual valves that are used within these systems on the stages and engines. This requires us to integrate our designs with those of the structures, propulsion, avionics hardware teams. It also requires us to work closely with the GNC and performance teams to ensure that our systems can meet the requirements of launching and landing a reusable rocket. Finally, we also work closely with the manufacturing and test teams to ensure our hardware is adequately built and tested.
About the Role:
In this role, you will be responsible for the mechanical and structural implementation of the stage fluid systems, ensuring a reliable and efficient operation of our Terran R launch vehicle.
- Fluids routing and design trade studies
- Fluids hardware mounting structure design
- Fluid system hardware mechanical verification analysis including both hand calcs and FEA
- Structural design of mounting hardware for various fluid system component and routing
- Incorporate 3D printing methods and in fluid system mechanical design
- Design for Manufacturing (DFM) and Design for Assembly (DFA)
The right person for this role will need to be someone who enjoys leading the way for the team on exploring new methods and design approaches. They will have end to end ownership of their designs and immediately see hardware you designed come to fruition. They must be flexible to changes in strategic direction and willing to take full ownership of their projects to ensure we as a company are producing the best possible product while incorporating innovative production methods into their designs.
About You:
- Bachelor’s degree in mechanical or an equivalent engineering discipline
- 5+ years mechanical design experience
- Experience with a commercial CAD package (NX, CREO, Solidworks)
- Experience with GD&T
- Project ownership experience
- Manufacturing experience or experience interacting with vendors
- Experience with fluid system components (fittings, seals, valves, regulators, etc.) and system testing
- Experience with FEA tools to analyze structural margins
