Senior Weld Engineer
About The Position
Relativity Space is building rockets to serve today’s needs and tomorrow’s breakthroughs. The Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. Commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation. Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Engineers solve problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Collaboration across teams, shaping decisions, and seeing work come to life in record time are key aspects of the role. Creativity and technical rigor go hand in hand, and your voice will help define the stories being written together. This is an opportunity to leave your mark on the product, the process, and the culture, while Terran R is tangible and picking up momentum.
