Senior Avionics Ground Support Equipment Engineer

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.

About the Role

• Design, develop, integrate, and build of critical ground systems that support engine test, vehicle integration, and test and launch operations
• Collaborate cross-functionally with propulsion, avionics, software, test, and operations teams to deliver robust, scalable systems on tight timelines
• Oversee fabrication, bring-up, and validation of EGSE systems, including electrical testing, calibration, and functional checks
• Author interface control documents (ICDs) and engineering release drawings to ensure tight alignment between EGSE and flight/avionics hardware
• Work closely with safety, operations, and launch teams to ensure systems are compliant and operable under high-stakes conditions
• Mentor junior engineers and establish best practices in GSE development and documentation

About You

• B.S. in Electrical Engineering, Mechatronics, Aerospace Engineering, or related field
• 5+ years of hands-on experience designing and deploying EGSE or electrical integration systems in aerospace or high-reliability environments
• Strong knowledge of signal integrity, grounding schemes, shielding, and power systems
• Hands-on experience designing, building, and commissioning electromechanical ground systems
• Familiarity with common communication protocols (e.g., Ethernet, RS-422, CAN, MIL-STD-1553) and ground systems standards (ASME, API, and NASA/AF)

Nice to haves but not required

• Proficient in mechanical CAD (e.g., SolidWorks) for rack layout and enclosure integration
• Familiarity with test automation and scripting (e.g., Python, LabVIEW, MATLAB)
