About this job

Open Cosmos are revolutionising space technology and opening up the cosmos to everyone. Our simple, affordable satellite missions give organisations the chance to use space technology as a tool to get your ideas into orbit. Our mission is to make the leaps in space that become the leaps on Earth.
