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><span data-contrast="none">About the Team: </span></strong></span></p>
