Staff Launch Mechanical Engineer
Relativity Space
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 Launch team operates at the intersection of every major aspect of Terran R, from stages and payloads to ground systems, launch, landing, and refurbishment. The Cape is the only place where you see it all come together, offering a level of exposure and responsibility unmatched elsewhere in the program. This is where first flights happen, where history is built on top of history, and where the scale of what's underway is unlike anything in modern aerospace. The mission stays the same, but the work evolves with every milestone: from first launch to reuse, high-cadence operations, and beyond. If you're looking to define what's next in space launch and write a new playbook, not just repeat what’s already been done, this is where it happens.
About the Role:
- Apply mechanical engineering principles to lead mechanical design projects from concept through implementation.
- Coordinate and interpret requirements between vehicle vehicle and other ground support engineering teams
- Develop detailed 3D CAD models, 2D drawings, fluid system schematics, and electrical system schematics to support design execution.
- Conduct structural, dynamic, and system performance analyses using both analytical and finite element methods.
- Present design solutions and technical findings to engineering and leadership teams, ensuring clarity in design approach, functionality, and constructability.
About You:
- Bachelor’s degree in mechanical engineering, aerospace engineering, or a related field.
- Minimum of 10 years of professional engineering experience in structural, mechanical, fluid power, or related systems.
- Strong technical foundation in structural analysis, mechanical design, and fluid systems.
- Proven ability to manage projects on schedule and deliver results in a fast-paced environment.
Nice to haves but not required:
- Experience designing, manufacturing, testing, and implementing launch vehicle interface mechanisms and tooling.
- Familiarity with NASA, DoD, Space Force, or similar regulatory and industry standards.
- Working knowledge of structural materials and common manufacturing processes.
- Experience designing complex fluid systems, including high-pressure gas, cryogenic fluids, flammables, or hydraulics.
