Job description

Avionics Manufacturing Engineer Intern

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 Avionics team is responsible for the full lifecycle of Terran R’s nervous system, designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground. The team leverages close partnership between avionics design, manufacturing, and test to enable rapid iteration and feedback loops. Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: you’ll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly.

About The Role

The Avionics Manufacturing team owns the build and test of PCBA, electromechanical assembly, harness, and instrumentation systems on Terran R. As an intern on this team, you'll work alongside design, quality, test, and manufacturing engineers to help turn new electronic hardware into reliable, high-volume production. Your projects will include authoring work instructions, designing assembly and test fixtures, qualifying new equipment, and supporting the production team as we scale rate across all of our products. The processes you build here will be used to support flight hardware.

About You

• Pursuing a BS or MS in aerospace, electrical, mechanical, manufacturing, or industrial engineering
• Hands-on experience through labs, projects, internships, or hardware teams (rockets, robotics, Formula SAE)
• Strong collaboration skills across engineering, manufacturing, and production teams
• Self-motivated problem-solver who balances a scrappy, get-it-done attitude with a vision for scalable, long-term processes

Nice To Haves But Not Required

• Internship or co-op experience in manufacturing, aerospace, or related fields
• Machine shop, CNC machining, 3D printing, or CAD/CAM software experience (Siemens NX, Mastercam, Fusion 360)
• Familiarity with GD&T, technical drawings, and aerospace materials/processes
• Familiarity with troubleshooting electrical systems (understanding circuits and harnessing schematics)
• Exposure to lean manufacturing, Six Sigma, or continuous improvement methodologies
• Project management or new product introduction experience in fast-paced environments
