Principal Mechanical Engineer, Tooling

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 Tooling and Factory Automation team sits at the intersection of design, manufacturing, and automation, making everything from large-scale structural fixtures to small tools that directly enable Terran R’s production. As a design group embedded within the manufacturing organization, we dig deep into the needs of our internal partners to understand root problems, propose solutions, and deliver hardware to help build faster, scale smarter, and work better. The team is also at the forefront of Relativity’s growing factory automation efforts, an increasingly critical part of scaling production of Terran R at existing and future facilities. You’ll have the autonomy to make decisions, field solutions, and see them in action on the factory floor. Ultimately, you’re not just designing tools or automated processes; you’re defining how rockets and factories get built.

About the Role

The Mechanical Design Engineers are responsible for the design and development of tools and factory automation equipment that support manufacturing. The Mechanical Engineering team works closely with Design and Manufacturing, turning top-level requirements and concepts into functional delivered equipment. The Mechanical Design Engineering team brings a high level of innovation and ingenuity into the design process, as they are tasked with building out a highly automated production facility.
