Lead Launch Mechanical Engineer

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 Mechanical team is responsible for building world class launch facilities to support flights of the Terran R launch vehicle. As part of the team, you will take on the challenge of designing, building, testing, and integrating complex mechanical systems that interface directly with the launch vehicle. You will have the opportunity to be part of a small team of engineers who are responsible for the full engineering cycle on projects that involve static structures, dynamic mechanisms, and control systems using fluid, electrical, and combustion powered sources.

About the Role:

• Manage a small, highly talented team of launch mechanical engineers to design mechanisms and tools that interface with the flight vehicle and other ground systems

• Mentor engineers on fundamental and practical engineering practices

• Balance leadership work with individual technical projects

• Directly and indirectly impact the outcome of launch system designs

• Grow the team by recruiting, interviewing, developing training materials, direct mentorship, and performance reviews

• Communicate with leadership about progress, risks, and other team details

About You:

• Bachelor's degree in mechanical engineering, aerospace engineering, or a related field

• Varied perspectives & backgrounds strengthen our team

• Minimum of 3 years of engineering experience in a test or launch environment

• Strong engineering fundamentals in structures, mechanical design, and fluid systems

• Demonstrated drive to deliver on tight schedules, especially when unconventional & creative solutions are necessary

• Strong leadership skills, including mentorship, communication, conflict resolution, and managing expectations

Nice to haves but not required:

• Experience designing, manufacturing, testing, and implementing launch vehicle interface mechanism systems and tooling

• Familiarity with NASA, DoD, Space Force, and other governing body standards

• Working knowledge of common structural materials and manufacturing processes

• Experience designing complex fluid systems, including high pressure gas, cryogenic fluids, flammables, and hydraulics
