What are the responsibilities and job description for the Flight Software Engineer Intern - Fall 2025 position at Relativity Space?
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 Flight Software team is responsible for developing and testing the software that runs on the vehicle. This includes software that autonomously controls all portions of the rocket from the launch pad to orbit, software which allows communication and insight into the vehicle systems, and software that runs on various other flight-critical hardware boxes. This team is at the forefront of driving Relativity Space towards our mission of a multiplanetary future, from changing how we manufacture rockets to how we fly them.
About the Role:
You'll have experience developing and testing flight software, interacting with Avionics and Guidance, Navigation and Control (GNC) teams, and interfacing with hardware in the Avionics lab. At Relativity, the software you develop will be a core piece of a software system that controls the entire vehicle operation and is mission critical. You'd be a strong fit if you have a strong passion for and foundation of what it means to develop highly reliable software, following best practices around code quality and testing.
