Electronics design experience

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

As an Avionics Test Systems Engineer, Test Platforms at Relativity Space, you will be responsible for designing, developing, and maintaining the Hardware-in-the-Loop (HITL) testbeds for avionics subsystems. This will involve working closely with the avionics and flight software teams to understand their testing needs and develop appropriate test systems. You will also be responsible for designing the HITL test infrastructure, maintaining configuration of the HITL platform, developing validation procedures, and providing feedback to design teams and system integration.
