About The Position

Relativity Space is building rockets to serve today’s needs and tomorrow’s breakthroughs, with their Terran R vehicle designed to deliver customer payloads to orbit. Joining Relativity means becoming part of a team where autonomy, ownership, and impact are paramount. 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. Engineers on this team are deeply embedded into other functions within Relativity, working closely with propulsion, GNC, fluids, and stage engineering teams to ensure seamless integration and operation. This role offers a unique opportunity to help shape Terran R's fundamental avionics architecture and be given a high degree of ownership on components that will fly. As an electrical hardware engineer on the Avionics team, you will design, test, and analyze custom electronics on the Terran R launch vehicle. You will oversee hardware development through the entire product lifecycle from concept to flight maturity, including initial design, board bring-up, design verification, qualification, initial flight production, integration, and vehicle operations. You will collaborate with cross-functional partner teams across the company to make the best possible decisions for the overall vehicle. A strong candidate will possess a deep technical background in electronics design and sound project management skills to ensure hardware projects are reliable and on-schedule.
