Sr Manager, Integrated Test Engineering

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 is responsible for all hazardous testing in our Long Beach facilities - from massive structural qualification tests to precision valve actuation and everything in between. We design, build, and operate test assets from initial concept through test execution, supporting the development and production of the Terran R launch vehicle. We bring together structures engineers, fluids engineers, data and control systems engineers, and test operators in a uniquely collaborative environment. We move fast, we build real hardware, and we solve problems that have never been solved before. If you want to lead the engineers who make the impossible testable, this is your opportunity. About the Role: As the Sr Manager of Integrated Test Engineering, you will lead a team of 20-25 engineers responsible for the structural, fluid system, and data/control system design of all test infrastructure in Long Beach. You will manage 2-3 engineering managers directly while also providing technical leadership and mentorship across all three disciplines. This role demands both exceptional technical breadth and the ability to foster collaboration across traditionally siloed engineering domains. Your primary responsibilities will include: Lead an integrated engineering team of 20-25 people across structures, fluids, and data/control systems, including 2-3 direct-report managers and individual contributors across all three disciplines • Allocate resources, review technical work, and resolve trade studies across multiple concurrent projects - you'll be balancing structural analysis reviews, fluid system design reviews, and control architecture decisions on the same day Break down silos and drive cross-functional collaboration - your team will design test stands where the structure, fluids, and controls are tightly integrated and must work together seamlessly Execute on the engineering roadmap established with the Director and Vehicle Design team, translating strategy into delivered hardware on schedule and on budget Recruit, develop, mentor, and retain top-tier engineering talent across multiple technical disciplines - you'll be hiring structures engineers, fluids engineers, and DACS engineers, and you need to evaluate excellence in all three domains Provide technical review and leadership on complex, multi-disciplinary problems where structures, fluids, and controls intersect - your technical breadth will be your superpower Implement and uphold design standards, safety protocols, and quality processes across all three engineering disciplines Drive project execution - track schedules, manage budgets (multi-million dollar projects), coordinate with procurement, and r ...
