Avionics Manufacturing Technical Specialist

Avionics Manufacturing Technical Specialist I

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.

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.

This is a 1st shift position with a standard schedule of 5:00 AM – 3:30 PM PT, Monday through Friday. Please note that this position is structured around a baseline expectation of a 50-hour workweek, which may include occasional overtime as needed to meet operational goals.

• Create Process Plans, Standard Operating Procedures, and other supporting documents to define the process to manufacture avionics.
• Hands‑on assembly, rework, and inspection of PCBAs & avionics electromechanical.
• 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.
• Drive avionics box builds on the production floor, ensuring consistent build quality, configuration control, and documentation of as‑built configurations.
• Collaborate closely with design engineers, manufacturing engineers, and quality to troubleshoot build issues, implement process improvements, and maintain flight‑readiness standards.

• 3+ 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.
• In‑depth knowledge of IPC‑A‑610, J‑STD‑001, and general high‑reliability workmanship standards.
• Comfortable reading and interpreting complex electrical schematics, mechanical drawings, and assembly documentation.
• Excellent communication skills and attention to detail; capable of documenting build issues clearly and contributing to root‑cause investigations.

• IPC‑A‑610, J‑STD‑001, or NASA‑STD‑8739.x certification (current or expired).
• Experience with flight hardware builds for aerospace or space systems.
• Familiarity with cable and harness assembly, including wire crimping, stripping, and routing (per IPC/WHMA‑A‑620 or similar).
• Experience working in a cleanroom or controlled…
