Infrastructure Engineer Intern - Fall 2026

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 Construction Design and Delivery team is at the core of Relativity’s growth and development. Through our collaboration and expertise, we deliver projects that lay the foundation for Relativity’s future success. In essence, we build the factory that builds the rockets! We are responsible for cross functional relationships with teams such as Manufacturing, Propulsion, PBF, Avionics, Machine Shop, Facilities, EHS and Security to name a few, working through design specifications and execution of critical infrastructure projects that supports the mission of work centers. Our relationships don’t stop there, working daily with government agencies, utility suppliers, vendors and contractors who support our factory build out. Our team ensures that all projects meet operational requirements, safety and environmental codes, all the while remaining within budget, delivering on time, and to the highest quality as we help to drive production forward.
