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 Factory Test team designs, builds, and operates the infrastructure needed to test nearly every part of Terran R right here at our headquarters in Long Beach, CA. This centralized approach provides engineers and technicians with exposure to the entire product lifecycle across a wide range of part sizes and complexities. The scope and scale are significant, with test stands capable of handling millions of pounds of force. Team members lead multiple projects in parallel, avoiding silos and gaining broad technical experience without needing a background in aerospace. With high-impact campaigns ahead, now is the time to join. You won’t just execute, but you’ll help shape and scale the test infrastructure required to meet the demands of a rapidly growing launch program.

About the Role:

• Design, build, and operate pressurized cryogenic/pneumatic/hydraulic systems to support cutting-edge rocket testing
• Develop and manage advanced data control systems for real-time monitoring and analysis
• Provide expert guidance to engineers on testing best practices, system capabilities, and operational limitations
• Conduct first-level triage of test failures, reading telemetry and logs to determine root causes
• Proactively identify and mitigate hazards to ensure a safe and efficient testing environment
• Develop test plans, conops, and high level P&IDs for production or development testing that other teams will execute

About You:

• 5+ years of relevant technical experience, including (but not limited to):
• Experience working with pressurized flight components
• Operating hazardous equipment with multiple sources of energy
• Building Complex Fluid-Mechanical Systems
• Console operation of large scale test stands with multiple sources of energy
• In-depth knowledge and experience with test automation, data acquisition, and control systems
• Proficiency with Basic Office Software (Excel, Word, Outlook, Slack)
• At minimum: High School Diploma or GED

Nice to haves but not required:

• Associates Degree or Trade Certifications in pertinent disciplines: e.g., Aviation/Automotive Mechanic
• Knowledge of rocket engine components such as pumps, valves, regulators, check valves, as well as electric, pneumatic, and hydraulic valves, actuators, and other fluid system components
• Expertise in Python-based test scripts
