At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before. We build, test, launch and operate satellites to solve the problems of our customers. It’s an exciting time to join as we scale up to meet the demands of the fast-growing space industry. Working in our ground segment team You can think of our satellites as essentially Linux computers 500km away travelling at 8km/s that we can only talk to for a few minutes per day. In that time we download telemetry, verify satellite health, respond to anomalies, plan the next orbit's activities and retrieve payload data such as images. These constraints create unique and exciting engineering challenges. The Ground Segment team builds and runs software to test and operate satellites with high levels of automation. The operational infrastructure we provide is critical to the success of our missions, and the tools we build on top make everyone in the company more productive. We're scaling fast to support upcoming missions. Our operations platform runs Go and Python microservices on Kubernetes, backed by PostgreSQL, with a React/TypeScript frontend. We favor proven technologies so we can focus on the problems that actually matter: reliably operating a growing constellation at scale.
