Avionics Test Systems Engineer, Ground Systems

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll collaborate across teams shape decisions and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand and your voice will help define the stories were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Avionics team is responsible for the full lifecycle of Terran Rs nervous system designing building testing installing and operating the hardware that connects and controls every major electrical system on the vehicle and ground.

The teams 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. Now is a unique time to join: youll get to help shape Terran Rs fundamental avionics architecture and be given a high degree of ownership on components that will fly.

About the Role:

We are seeking Avionics Test System Engineer Ground Systems supporting our vehicle ground test support systems. Candidates with strong experience in designing building and deploying test systems that interface directly with flight this role youll lead the development of robust electrical and mechanical systems that support vehicle test integration and launch in challenging environments. Youll work cross-functionally with avionics propulsion structures test and software teams to ensure our ground systems are reliable flexible and safe. This position is ideal for someone who thrives on high ownership fast iteration and seeing their systems go from concept to launchpad. As an Avionics Test System Engineer Ground Systems you will:

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

About You:

• Undergraduate or graduate degree (BS/MS/PhD) in Electrical Engineering Computer Engineering Mechanical Engineering Aerospace Engineering or a related field
• 1 years of hands-on experience designing and deploying test systems or electrical integration systems in aerospace or high-reliability environments
• Strong knowledge of electrical 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).
• Familiarity with data acquisition and control system platforms such as NI Beckhoff or similar

Nice to haves but not required:

• Experience with wire harness design tools such as Zuken
