Relativity Space is on a mission to better connect humanity to space and the universe beyond our planet. With decades of experience scaling world-class technology organizations like Google, CEO Eric Schmidt is guiding Relativity into its next phase: advancing Terran R toward launch and building the foundation for long-term impact. 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.
