<div class="content-intro">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.</div>About the Team: 
Relativity’s Integrated Performance teams ensure that our products work across all systems and disciplines, from trajectory design to aerodynamics to reliability analysis and beyond. Our groups size the Terran R rocket, design its missions for customer success, reliability, and reusability, and ensure that every system on the rocket and ground is engineered correctly for the demanding environments of launch and entry. Recently, we completed the preliminary design and analysis of Terran R including Relativity’s first-ever work on launch vehicle reusability, spanning advanced trajectory simulations, wind tunnel testing, and structures analysis, among many other projects.
The Thermal team is responsible for predicting temperatures and designing thermal architectures for structures, fluids, components, and avionics on reusable launch vehicles. With a strong grasp of thermodynamics and all types of heat transfer, the team addresses a vast amount of thermal challenges across all forms of ground use and flight phases. Leveraging first principle hand calculations, reduced order modeling, as well as detailed thermal modeling, the team is able to drive cross disciplinary vehicle designs. Our collaboration with hardware engineers and all other teams further enables us to overcome design and integration hurdles, ensuring a seamless and efficient development process from concept and through launch.
