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 additive technology team leads research and development of Relativity’s Stargate 3D-printing platform and factory operating system to produce large-scale metal structures for the industrial base. The team works with robotics engineers, data scientists, systems engineers, and welders to advance Relativity’s innovative tech stack, which leverages autonomy, advanced simulation, machine learning, and robotics. Working at the intersection of hardware and software, the team is creating a unified platform that can perform additive manufacturing, in-situ monitoring, NDE, and subtraction capabilities in a single print cell. Progressing in parallel to Terran R development, Relativity’s breakthroughs in large-scale additive manufacturing have the potential to revolutionize the defense industrial base.

About the Role:

Our mission is to induce a paradigm shift in how rockets are built and flown. You will participate in developing and maintaining a working knowledge Relativity’s Stargate-Class 3D printer design as well as your domain expertise to contribute to the assessment of proposed design changes and impact based on test evidence.
