Senior Avionics Electromechanical Technician, First Shift

Long Beach, California

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'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. 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.

About the Role:

• Assembling electromechnical builds
• Build flight and development avionics hardware from the ground up — integrating PCBAs, connectors, cabling, thermal interfaces, fasteners, and enclosures into complete units
• Interpret engineering drawings, wiring diagrams, mechanical assembly models, and work instructions with minimal supervision
• Collaborate closely with design engineers, manufacturing engineers, and quality to troubleshoot build issues, implement process improvements, and maintain flight-readiness standards
• Ability to perform minor PCBA rework in alignment with IPC-A-610, J-STD-0001

About You:

• 5+ years of experience in electronics manufacturing, with hands-on expertise in both PCBA rework and electromechanical assembly
• Strong mechanical assembly skills, including torque tools, bonding, and integration of electronics into enclosures or chassis
• Comfortable reading and interpreting complex electrical schematics, mechanical drawings, and assembly documentation
• Be able to manufacture components to a high workmanship standard, including some soldering and wire harnessing.

Nice to haves but not required:

• Proficient in fine-pitch soldering, component-level troubleshooting, and rework using hot air, soldering iron, and rework stations
• IPC-A-610, J-STD-001, or NASA-STD-8739.x certification (current or expired)
• Familiarity with cable and harness assembly, including wire crimping, stripping, and routing (per IPC/WHMA-A-620 or similar)
• Background using MES/ERP systems for tracking work orders, part usage, and nonconformances
