Lead Engineer, Avionics Battery Test

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll 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 were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

The Avionics team is responsible for the full lifecycle of Terran Rs nervous system designing building testing installing and operating the hardware that connects and controls every major electrical system on the vehicle and ground. The team leverages close partnership between avionics design manufacturing and test to enable rapid iteration and feedback loops. Engineers are deeply embedded into other functions within Relativity working closely with propulsion GNC fluids and stage engineering teams to ensure seamless integration and operation. Now is a unique time to join: youll get to help shape Terran Rs fundamental avionics architecture and be given a high degree of ownership on components that will fly.

About the Role:

As the Lead of Avionics Battery Test Engineering you will build and lead the team responsible for all high-voltage battery testing at Relativity spanning performance electrical abuse and destructive test programs at both the pack and cell level. You will stand up this capability from the ground up: defining the test strategy building out lab and test infrastructure establishing safety and procedural standards and hiring and developing a team that includes electrical/performance test engineers and abuse/destructive test engineers as well as cell-science expertise. You will oversee HV battery bring-up pack- and cell-level testing structured failure analysis and the data systems that turn test results into rapid high-quality feedback for design teams. This role requires a strong technical foundation in battery testing and energetics hands-on lab expertise and experience managing test teams in fast-paced development environments.

About You:

• Bachelors degree in engineering (mechanical electrical chemical aerospace or related field)
• Extensive experience in battery testing validation or energetics system evaluation including hands-on execution of test programs
• Strong understanding of battery physics safety behavior failure modes and HV system fundamentals
• Experience defining and executing performance durability abuse and destructive test programs
• Hands-on experience with battery test equipment cyclers chambers DAQ systems and instrumentation hardware
• Experience with HV battery bring-up sensor instrumentation test fixture design and test setup design
• 3 years leading test engineering teams including development of engineers technical and leadership skills
• Strong safety mindset and comfort overseeing high-energy high-consequence test operations
• Strong analytical communication and cross-functional collaboration skills
