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>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">The Propulsion team at Relativity is focused on developing and delivering highly performant and manufacturable engines for Terran R. Engineers are responsible for the entire lifecycle of their parts, from initial design through production to qualification and flight. The team fosters a culture of bottoms-up decision-making, free from technical gatekeeping, where ownership and accountability are key at all levels. But designing engines with a quarter million pounds of thrust is just the beginning. As the flight configuration enters qualification, the team is now exploring modifications for future engines, including thrust upgrades, new cycles, and design for mass production.</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><strong><span data-contrast="none">About the Role:</span></strong></span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">In this role, you will lead a team of ~20 engineers who own development of the Aeon engine series at the system level. The team’s work spans component integrated system hotfire testing, thermofluids simulation, system-level architecture, requirements, and interfaces; and more. We collaborate closely with propulsion design 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-family: arial, helvetica, sans-serif; font-size: 10pt;">Your responsibilities will include the following:</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;">Lead, mentor, and develop a team of propulsion development engineers, fostering a culture of growth continuous improvement</span></li>
<li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;"><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Solve a variety of technical problems across broad ranges of timeframe, scope, and complexity</spa ... (truncated, view full listing at source)
