Covering engineering, product development, and technical innovation, the team designs, builds, and operates the satellites, systems, and platforms that make our missions possible.

Our Ground Segment team builds and runs the software that powers Open Cosmos missions.

You’ll review code, mentor other developers, and champion React best practices. As our software grows, you’ll tackle performance challenges, improve reliability, and continuously enhance our tools, processes, and CI/CD workflows.
