About The Company

Relativity Space is on a mission to make access to space more reliable and routine. Our medium-to-heavy lift reusable rocket, Terran R, 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.

About the Role

<div class="content-intro">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. 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 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.</div>About the Team:  The Vehicle Software team develops the safety-critical software that runs on Terran R. 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. About the Role: As an Embedded Software Engineer II, you will design, implement and test firmware running across Terran R’s avionics boxes.  You will work closely with the avionics hardware team and test engineers to develop high reliable embedded software that enables vehicle wide communication, control and telemetry. <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Design, develop and maintain vehicle embedded software</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Implement low level drivers, communication stacks under RTOS environment</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Collaborate with hardware engineers on board bring up, debugging and system integration</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Support software testing through unit testing, hardware in the loop and integration testing</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Participate in code reviews, design discussions and continuous integration efforts</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Contribute to design documentation and interface specifications shared across vehicle systems</li> </ul> About You: <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Bachelor’s in computer science or related technical field</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">2+ years relevant experience in firmware development in C/C++</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with software development processes including source control, bug tracking, and design documentation</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Demonstrated experience working collaboratively in cross-functional teams</li> </ul> Nice to have but not required:   <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with developing safety critical software</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Prior work experience in aerospace industry</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Familiarity with network stack implementation, socket-level programming, and transport protocols such as UDP, TCP/IP, and multicast data distribution</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Experience with firmware development in RTOS environment (preferably FreeRTOS)</li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Familiarity with hardware in the loop testing (HITL) and CI/CD pipelines for embedded systems</li> </ul><div class="content-pay-transparency"><div class="pay-input"><div class="description">At Relativity Space, we are committed to transparency and fairness in our compensation practices.
