Relativity Space · Long Beach, California

Mission Brief

Core Responsibilities

<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-size: 10pt; font-family: arial, helvetica, sans-serif;"><strong>About the Role:</strong> </span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">This role is on the Engine Systems & Test Team. Our work spans simulation & software tools; system-level architecture, requirements, and interfaces; component & integrated system hotfire testing; and more. We collaborate closely with component engineers, our manufacturing team, our Stennis test team, and our Cape launch team to deliver engines that will successfully propel the Terran rocket to orbit. We strive for continuous improvement and support the development of our technical hardware and human teammates alike. </span></p> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">We are hiring for the integrated engine test team (which tests the full engine assembly). Your work may span several different areas depending on your skillset and the team’s needs at the time.</span></p> <ul> <li style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">In the test part of your role, you will serve as a Responsible Engineer for propulsion test articles.</span> <ul> <li style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">You will develop test plans in collaboration with product owners, and you will execute test campaigns with our Stennis team, troubleshooting technical puzzles along the way.</span></li> <li style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">You will own the exploratory operation of new and existing test article designs, diving deep into the evaluation of test hardware behavior in support of continuous engine development and certification.</span></li> <li style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">This role is extremely varied day-to-day and, in addition to overall campaign ownership, can include writing test sequences, reviewing data, hands-on work with test articles, writing code, sitting console for hotfire tests, designing tooling, and more.</span></li> </ul> </li> <li style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Most test roles also involve systems work – on this side of your role, you may support engine subsystem troubleshooting, partner team product investigations, engine system analysis and simulation, trade studies, and more.</span></li> <li style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">You will also take ownership of projects of your creation to increase our collective efficiency.</span></li> <li style="font-size: 10pt; font-family: arial, helvetica, sans-serif;"><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">As our vehicle development program progresses, you may have the opportunity to be involved in stage test and flight campaigns – including sitting console for launch operations, defining stage test objectives, and defining flight concepts of operations (CONOPS).</span></li> </ul> <p><span style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">In order to be successful in this role, you should be a self-starter who is capable of leading collaborative projects to completion.
