Avionics Test Integration Engineer II

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. 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’s structure intentionally combines 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: You will own the design, release, integration, and maintenance of Avionics Test Infrastructure which includes ground support harnessing, test racks, and test fixtures supporting vehicle manufacturing and test ground support equipment. Individuals in this role will support designs for short term rapid prototyping to long term production scaling working with design engineers, test engineers, and manufacturing engineers. About You: * Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Mechanical Engineering, Aerospace Engineering, or a related field * 3+ years of experience designing and releasing ground equipment infrastructure such as test racks, test harnesses, and test fixtures * Experience designing mechanical test solutions for electronic devices and equipment

• Experience with CAD tools such as NX and Teamcenter
• Experience with wire harness design tools such as Zuken or Capital Harness
