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

Environmental Test Lab: Vibration Test Team

The Vibration Test Team provides vibration testing services across the Terran R program, supporting hardware and systems for Avionics, Propulsion, and Mechanisms. The team partners closely with engineering organizations to execute environmental testing that validates hardware performance and readiness throughout development and qualification.

This is a second-shift position with a standard schedule of Monday through Friday, 3:00 p.m. to 1:30 a.m. PT. The role is structured around a 50-hour workweek, including 10 guaranteed overtime hours each week. In addition to base pay, employees receive a 10% shift differential.

About the Role

As an Environmental Test Specialist focused on vibration testing, you will execute acceptance, qualification, and development testing on Terran R hardware. This role requires strong hands-on knowledge of electromechanical shaker systems, instrumentation, test setup, and troubleshooting.

In this role, you will:

Set up and execute vibration acceptance, qualification, and development tests
Operate electromechanical shaker systems and understand the function and interaction of their major components
Troubleshoot vibration test setups, including control issues, instrumentation problems, and fixture-related concerns
Install, configure, and validate accelerometers and other test instrumentation
Understand vibration control systems and identify abnormal test or system behavior
Work closely with engineering teams to communicate test status, troubleshoot issues, and support successful test execution
Work safely around high-voltage systems, high-pressure systems, and cryogenic environments
Clearly document and communicate test configurations, observations, issues, and results

About You

5+ years of hands-on vibration testing experience
Strong working knowledge of vibration control systems and vibration test equipment
High proficiency with accelerometers, instrumentation, data acquisition, and measurement equipment
Demonstrated ability to troubleshoot vibration test setups, control problems, instrumentation, and test fixtures
Working knowledge of electrical theory and electrical systems
Working knowledge of thermal principles and their impact on hardware and test environments
Strong computer skills and ability to work with test control, data acquisition, and technical software
Strong technical communication and documentation skills
Comfortable working hands-on with complex test hardware in a dynamic test environment

Technical or vocational training is preferred. Aerospace, defense, or other high-reliability hardware testing experience is strongly preferred.
