Environmental Test Specialist

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 team is responsible for all aspects of the electrical design on the rocket, from electronics, interconnects, associated mechanical design, testing and initial production. This team's scope includes the flight computers, power systems, RF systems, PCB design, autonomous flight safety systems, and telemetry. This team works on complex electrical systems that require modularity and flexibility, and are critical to the successful launch of Terran R, and beyond!

About the Role:

* Lead hands-on execution of environmental testing operations in support of Terran R avionics development and production hardware, including vibration, shock, and thermal testing activities

* Execute qualification test procedures (QTP) and acceptance test procedures (ATP) with minimal supervision while ensuring safe, repeatable, and efficient test execution

* Support setup, instrumentation, operation, troubleshooting, and teardown of environmental test configurations across vibration tables, shock systems, and thermal chambers

* Configure and operate data acquisition systems, accelerometers, thermocouples, and supporting instrumentation required for environmental test execution and data collection

* Interpret engineering drawings, test procedures, schematics, and hardware handling requirements to ensure proper test setup and execution

* Serve as a technical resource within the environmental test lab, supporting test readiness activities, fixture setup, hardware integration, and configuration control of flight and development hardware

* Collaborate closely with test engineers, avionics engineers, manufacturing teams, and quality personnel to troubleshoot test issues, improve workflows, and maintain flight-readiness standards

* Export, organize, and communicate test data clearly to engineering teams to support post-test analysis, anomaly resolution, and hardware disposition activities

* Support rapid development cycles and aggressive production schedules while maintaining high workmanship, safety, and documentation standards

About You:

* 5+ years of experience supporting environmental testing operations within aerospace, defense, electronics, or other high-reliability hardware environments

* Hands-on experience independently executing acceptance testing (ATP) and environmental test procedures with minimal supervision

* Strong understanding of vibration, shock, and/or thermal testing operations, including test setup, instrumentation, and hardware handling practices

* Experience configuring and operating environmental test equipment and supporting instrumentation, including thermal chambers, vibration systems, accelerometers, thermocouples, and data acquisition systems

* Ability to interpret test procedures, engineering drawings, schematics, and hardware requirements to execute complex test campaigns accurately and efficiently

* Experience exporting, organizing, and…
