Job description

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 Development Technician team is responsible for testing avionics hardware and systems across the entire product lifecycle of Terran R: component-, subsystem-, and vehicle-level. As an Avionics Development Technician at Relativity Space, you will be responsible for building and testing hardware to print standards from start to finish.

About the Role:

• Build and integrate wire harnesses for avionics systems, ensuring precise routing, termination, and compliance with build-to-print specifications and aerospace standards
• Assemble and maintain functional test racks and interface boxes, supporting system-level testing and validation across various stages of the Terran R product lifecycle
• Interpret and execute complex work instructions, schematics, and technical drawings with accuracy and attention to detail, contributing to high-quality builds and efficient troubleshooting
• Collaborate closely with engineering and leadership teams to resolve build issues, provide feedback on documentation, and support continuous improvement initiatives
• Demonstrate a proactive, growth-oriented mindset, embracing new challenges, learning opportunities, and contributing to a culture of excellence and innovation in a fast-paced environment

About You:

• Must have a high school diploma or GED
• Minimum 2 years in avionics, electronics assembly, or manufacturing, with a focus on harness fabrication, test rack construction, and interface box integration
• Skilled in using electrical hand tools (e.g., wire strippers, crimpers, multimeters) and interpreting wiring diagrams and schematics to meet build standards
• Strong root cause analysis skills and attention to detail when diagnosing issues in test setups and verifying build integrity
• Ability to lift 25 lbs. unassisted, ensuring efficiency in handling materials and assemblies, and proficient in distinguishing colors for accurate wire identification and termination
• Capable of training and mentoring new technicians on proper build procedures, safety practices, and quality standards to ensure team consistency

Nice to haves, but not required:

• An associate degree or higher in electronics, avionics, or a related field
• Experience as a R&D technician working on high-complexity, mission-critical hardware, preferably within the aerospace industry
• Current or previous certification in IPC J-STD-001, IPC-A-610, or similar industry standards, reflecting advanced soldering skills and commitment to quality
• Capacity to thrive in a dynamic, high-pressure aerospace environment, consistently meeting rigorous performance and quality standards
