Aim high, go beyond
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 - ready for the challenge? Then read on…
The CTO division is where Open Cosmos technology comes to life. Covering engineering, product development, and technical innovation, the team designs, builds, and operates the satellites, systems, and platforms that make our missions possible. It’s a highly collaborative environment where ideas become real hardware, software, and data solutions that deliver impact from space.
Working in the Flight Software Team
Working across the full mission lifecycle, the team designs, implements, and tests software for both onboard and ground systems, ensuring reliability, performance, and scalability across our growing satellite fleet. Collaborating closely with systems, electronics, and mission operations, the team brings together innovation and precision to make every Open Cosmos mission fly.
