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-size: 10pt; font-family: arial, helvetica, sans-serif;">The Systems Engineering team ensures that Terran R comes together as a cohesive, high-performing, and scalable system. Within the department, one team focuses on building tools and processes to manage requirements, track decisions, and identify and mitigate risk - enabling faster, more informed development across the program. Engineers work across domains to understand complex problems, identify solutions, and implement them – all with deep technical knowledge, not just documentation. The other team focuses on the vehicle itself, working across teams to ensure all subsystems of Terran R function together as intended, burning down technical risk, and driving informed decisions at every stage of the vehicle lifecycle. Engineers are empowered to lead high-impact efforts, from major test campaigns to console operations during launch, and are trusted to drive improvements across fluids, structures, avionics, and more. Regardless of which team you’re on, you’ll be part of a high-visibility, high-impact department at a pivotal moment in the program, where decisions made today on trades, architecture, and process will shape not just the first launch, but the long-term trajectory of Relativity.</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;">As a Senior Systems Engineer, you will collaborate with team members across the organization while contributing to the development of Relativity’s engineering processes and tools to enable the design, development, certification, and flight of the Terran R launch system.</span></p>
<p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Projects and responsibilities 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;">Develop the Systems Engineering tools and methodology roadmap, helping align the needs of various disciplines and the overall project from development to launch</span></li>
