Systems Engineer

Senior Guidance, Navigation, and Control Engineer, Space SystemsBroomfield, Colorado, United StatesKatalyst is an American technology company focused on dynamic space operations. We are building a fleet of dual-use multipurpose robotic space vehicles to create the future where maneuvering, upgrading, refueling, resupply and exploration are as routine as they are on Earth. Getting to space and overcoming the gravity well is only half the story. What you do there is the future. We are not building the trains. We are building the machines that lay down the tracks.
