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. 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.
As a Lead Avionics Test Systems Engineer for Ground Systems, you will lead the design, development, build, and integration of critical ground systems that support engine test, vehicle integration, and launch operations. You will collaborate cross-functionally with vehicle, propulsion, avionics, software, test, and operations teams to deliver robust, scalable systems on tight timelines. Your responsibilities include overseeing fabrication, bring-up, and validation of test systems, including electrical testing, calibration, and functional checks. You will author interface control documents (ICDs) and engineering release drawings to ensure tight alignment between electrical ground support equipment and flight/avionics hardware. You will work closely with safety, operations, and launch teams to ensure systems are compliant and operable under high-stakes conditions.
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. This is a unique opportunity to help shape Terran R's fundamental avionics architecture with high degree of ownership on components that will fly.
REQUIREMENTS:
- Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering, Computer Engineering, Mechanical Engineering, Aerospace Engineering, or related field
- 5+ years of hands-on experience designing and deploying test systems or electrical integration systems in aerospace or high-reliability environments
- Expert knowledge of electrical signal integrity, grounding schemes, shielding, and power systems
- Hands-on experience designing, building, and commissioning electrical power and communication ground systems
- Experience with common communication protocols (e.g., Ethernet, RS-422, CAN, MIL-STD-1553) and ground systems standards (ASME, API, and NASA/AF)
- Experience with data acquisition and safety control system platforms such as NI, Beckhoff, or similar
NICE TO HAVES:
- Experience with wire harness design tools such as Zuken
- Experience with CAD tools such as NX and Teamcenter
- Familiarity with PCB design modeling tools such as Altium Designer
- Familiarity with scripting languages such as Python or MATLAB for data acquisition/recording and analysis
- Experience with Linux configuration management and ethernet networking
