Lead Avionics Survivability Engineer

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.

As the Lead Avionics Survivability Engineer, you will lead the survivability team responsible for ensuring Terran R's electrical and electronic systems can withstand the harsh environments of launch and spaceflight. Your team will oversee electromagnetic compatibility (EMC), radiation effects, and EEE (Electrical, Electronic, and Electromechanical) component reliability across the entire vehicle—from individual avionics components to vehicle-level system integration. You will drive analysis, test planning, qualification campaigns, and verification activities to ensure compliance with mission requirements and industry standards. This is a highly cross-functional role requiring coordination across avionics, propulsion, structures, GNC, flight software, and external stakeholders to establish survivability requirements, assess risks, and implement mitigation strategies. A strong candidate for this role will combine deep technical expertise in EMC, radiation effects, or physics with proven ability to lead multidisciplinary teams, manage complex test programs, and influence design decisions across the entire vehicle architecture.
