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 Avionics team is responsible for the full lifecycle of Terran R’s nervous system, designing, building, testing, installing, and operating the hardware that connects and controls every major electrical system on the vehicle and ground. The team leverages close partnership between avionics design, manufacturing, and test to enable rapid iteration and feedback loops. Engineers are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: you’ll get to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly. About the Role:  We are seeking a Ground Support Equipment (GSE) Engineer with strong experience in designing, building, and deploying Ground Support Equipment (GSE) racks and related systems that interface directly with flight hardware. In this role, you'll lead the development of robust electrical and mechanical systems that support vehicle test, integration, and launch in challenging environments. You’ll work cross-functionally with avionics, propulsion, structures, test, and software teams to ensure our EGSE is reliable, flexible, and safe. This position is ideal for someone who thrives on high ownership, fast iteration, and seeing their systems go from concept to launchpad.   As an Avionics Ground Support Equipment (GSE) Engineer, you will:  <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Design, develop, integrate, and build of critical ground systems that support engine test, vehicle integration, and test and launch operations </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Collaborate cross-functionally with propulsion, avionics, software, test, and operations teams to deliver robust, scalable systems on tight timelines </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Oversee fabrication, bring-up, and validation of EGSE systems, including electrical testing, calibration, and functional checks </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Author interface control documents (ICDs) and engineering release drawings to ensure tight alignment between EGSE and flight/avionics hardware </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Work closely with safety, operations, and launch teams to ensure systems are compliant and operable under high-stakes conditions </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Mentor junior engineers and establish best practices in GSE development and documentation </li> </ul>  About You:  <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">B.S. in Electrical Engineering, Mechatronics, Aerospace Engineering, or related field </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">5+ years of hands-on experience designing and deploying EGSE or electrical integration systems in aerospace or high-reliability environments </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Strong knowledge of signal integrity, grounding schemes, shielding, and power systems </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Hands-on experience designing, building, and commissioning electromechanical ground systems </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Familiarity with common communication protocols (e.g., Ethernet, RS-422, CAN, MIL-STD-1553) and ground systems standards (ASME, API, and NASA/AF)</li> </ul>  Nice to haves but not required:    <ul> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Proficient in mechanical CAD (e.g., SolidWorks) for rack layout and enclosure integration </li> <li style="font-family: arial, helvetica, sans-serif; font-size: 10pt;">Familiarity with test automation and scripting (e.g., Python, LabVIEW, MATLAB)</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.
