Job Description
<div class="content-intro"><p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">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.</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">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 </span><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">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.</span></p></div><p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong>About the Team: </strong> </span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">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’s structure intentionally combines 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.</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong>About the Role:</strong></span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"> You’ll use your experience and technical skill to ensure every build meets quality, documentation, and performance standards. In this role, you’ll serve as a technical resource on the production floor — guiding other technicians, assisting with troubleshooting, and ensuring best practices are followed. You’ll also collaborate closely with leads, engineering, and quality teams to identify build issues, improve processes, and maintain consistency across shifts.</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong>About you:</strong> </span></p>
<ul>
<li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Minimum 4 years of experience at the technician level</span></li>
<li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Must have experience from start to end builds</span></li>
