At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll 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 we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful work of your career is waiting. Join us.
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.
The Battery Technician is responsible for assembling, testing, maintaining, and repairing battery systems used in energy storage, electric vehicles, industrial equipment, and backup power applications. This role ensures batteries operate safely, efficiently, and in compliance with performance standards.
This is a second-shift position with a standard schedule of Monday through Friday, 2:00 p.m. to 12:00 a.m. PT. The role is structured around a 50-hour workweek, including 10 guaranteed overtime hours each week.
About the Role:
- Inspect, diagnose, and troubleshoot battery systems using meters, analyzers, and diagnostics software
- Verifying charge/discharge performance
- Assemble battery packs, modules, and wiring harnesses following technical drawings and safety protocols
- Conduct capacity test, load test, and quality checks to verify system performance
- Document test results, maintenance actions, and system performance data
- Replace defective cells, wiring, or components and ensure proper disposal of hazardous materials
About You:
- Knowledge of electrical systems, DC power, and basic electronics
- Ability to read wiring diagrams, schematics, and technical manuals
- Experience with multimeters, load testers, and diagnostic tools
- Strong attention to detail and commitment to safety
- Mechanical aptitude and hands on troubleshooting ability
- Knowledge in Li-ion cells and wire bond processes
Nice to haves but not required:
- Work with lithium ion, lead acid, or advanced energy storage systems
- Experience in EV, solar, aerospace, or industrial battery environments
- Familiarity with BMS (Battery Management Systems)
