Senior Software Development Engineer in Test

<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 Vehicle Software team develops the safety-critical software that runs on Terran R. The work spans a distributed, real-time control system operating under extreme conditions like Mach 5 atmospheric flight, with a deployment pace that allows you to see your code run on rocket engines daily. The team is building new system architecture from the ground up and just as importantly, testing, releasing, and deploying it. You don’t need an aerospace background: what matters is experience with high-reliability software for complex systems. This is a rare opportunity to shape the foundation of Terran R’s software stack while directly influencing performance, reliability, and flight success.</span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">TRADE (Test, Release, and Deployment Engineering) is a core engineering team within Vehicle Software at Relativity Space. As we scale from development to full-scale vehicle integration and launch operations, TRADE ensures our software is rigorously tested, confidently released, and successfully deployed across all environments from simulation to the launch pad.</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;">As a Senior SDET on the Vehicle Software TRADE (Test, Release and Deployment Engineering) team, you will own the automated validation lifecycle of integrated vehicle software. You will design and lead end-to-end testing frameworks that ensure each software release is reliable, traceable, and ready for use across production, integration labs, and launch environments. </span></p> <p><span style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">This role is deeply cross-functional and requires strong technical judgment, attention to detail, and proactive problem-solving. You will work with software, hardware, systems, and operations teams to define validation scope, align quality gates, and deliver releases that maintain readiness and consistency while adapting to evolving requirements, configuratio ...
