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. 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 is responsible for all hazardous testing in our Long Beach facilities. We use our breadth of experience and collaborative engineering approach to support everything from very large structural tests to precise valve actuation.

If you enjoy working on a multi‑disciplinary team with a broad mandate and want to get hands on hardware, this is the team for you.

About the Role

• Design, build, and operate pressurized cryogenic, pneumatic, and 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.
• Proactively identify and mitigate hazards to ensure a safe and efficient testing environment.
• Create, maintain, and refine test plans and procedures to drive consistent and reliable testing outcomes.
• Troubleshoot and resolve reliability issues, improving hardware performance and test efficiency.

About You

High School Diploma or GED. 3+ 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.
• Proficiency with basic office software (Excel, Word, Outlook, Slack).

Nice to haves but not required:

• Associates Degree or trade certifications in pertinent disciplines such as aviation or automotive mechanic.
• In‑depth knowledge and experience with test automation, data acquisition, and control systems.
• 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.

Compensation

Hiring Range: $33.80–$50.70 USD.

We offer competitive salary and equity, a generous paid time off and sick leave policy, parental leave, an annual learning and development stipend, and more.
