At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America’s leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

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
2+ years mechanical design experience
Experience with a commercial CAD package (NX, CREO, Solidworks)
Experience with GD&T, manufacturing, and interacting with vendors
Experience with fluid system components (fittings, seals, valves, regulators, etc.) and system testing
Experience with FEA tools to analyze structural margins
