Relativity Space is building rockets to serve today's needs and tomorrow's breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting growing demand for launch capacity. This role leads a team responsible for developing and scaling Relativity's electrical hardware and system test capabilities. As Manager of Avionics Electrical Test Engineering, you will oversee PCBA bring-up and debugging, integrated avionics system testing, and the development of automated test solutions for power electronics, low-voltage systems, digital/mixed-signal assemblies, and flight-critical avionics. You will lead, mentor, and grow a team of electrical test engineers while defining and driving test strategies for power electronics, low-voltage avionics, digital and mixed-signal hardware, and multi-box integrated systems. Key responsibilities include developing automated test infrastructure and scripted test frameworks with data capture and automated result analysis; overseeing board-level and system-level validation including functional, performance, environmental, and fault-injection testing; driving root-cause analysis and corrective action efforts across electrical components and integrated avionics systems; and partnering with hardware design teams to ensure design-for-testability. You will maintain a safe, high-quality lab environment including calibration, equipment readiness, and robust test processes. You'll manage scheduling, resource planning, and cross-functional alignment to support aggressive development and flight milestones, while championing continuous improvement of test methods, automation, documentation, and data-driven decision making. Required qualifications include a PhD or M.S. in Electrical Engineering (or B.S. with exceptional relevant experience); extensive experience in PCBA bring-up, debugging, validation, and electrical system troubleshooting; strong background in system-level testing of complex electrical systems such as avionics, inverters, OBCs, DC-DC converters, and power distribution; deep knowledge of power electronics and low-voltage hardware used in mission-critical environments; proficiency with electrical lab and measurement equipment; and 3+ years leading electrical test engineering teams.
