Full Stack Software Engineer I at Relativity in Long Beach, California, United States

Job description

• 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.
• As a Full Stack Software Engineer I on the Factory Platform team, you will build applications that directly support design and manufacturing engineers across the company. You'll work on projects like automating the analysis of telemetry data streaming from test stands, building tools to streamline supply chain and production planning processes, and creating dashboards that give engineers real-time visibility into manufacturing operations.
• You will participate in the full software development lifecycle, from understanding user requirements to designing, implementing, testing, and deploying solutions. You'll work across the stack—building responsive front-ends, scalable back-ends, and data pipelines that connect systems together. You'll follow agile development practices, write quality code that is continuously integrated and deployed, and iterate based on feedback from the engineers and operators who use your tools every day.
