At Relativity Space, we have two audacious goals: to build the next great commercial launch company with Terran R and to become America's leading force in additive manufacturing innovation. Both contribute to our long-term vision of creating humanity’s industrial base on Mars, paving the way for interplanetary life to expand the possibilities of the human experience. This journey begins right here on Earth – where we design, build, and fly rockets to deliver customer payloads to orbit. Terran R, our medium-to-heavy lift reusable rocket, fulfills the growing demand for launch capacity, thanks to our iterative approach that accelerates design, testing, and development while minimizing costs. While our groundbreaking research and development in 3D printing pushes the boundaries of large-scale additive manufacturing.

Your journey with us is more than just a job – it’s an opportunity to shape the future of aerospace technology, additive manufacturing, and the human experience alongside a community of passionate, creative individuals. Join us on this extraordinary journey, as we work together to transform our vision into reality.

About the Team:

The Stennis team at Relativity Space is responsible for designing, building, and operating world-class test stands to support the Terran R stages, engines, and components. As part of this team, you will help build and operate massive outdoor test stands at the historic Stennis Space Center on the Gulf Coast, the largest rocket engine test complex in the country. Unique to this location, you will have the opportunity to get hands-on experience with the fully integrated engine and stage assemblies, push the hardware to the limits, and witness rocket engines firing up close and personal! This team was critical to the launch success of Terran 1 and recently made fire on both sides of our dual bay Aeon R engine test stand, among many other firsts!

About the Role:

The Facilities Department at Relativity is responsible for maintaining and optimizing our physical assets—including buildings, infrastructure, and utilities. Guided by our team motto, People, Process, and Place, our team ensures operational excellence by managing maintenance programs for key systems such as HVAC, plumbing, and electrical. We uphold safety and environmental standards, oversee daily operations including energy management and custodial services, and respond to facility-related needs promptly.
