Principal Software Engineer /Senior Principal Software Engineer - TS/SCI

Long Beach, CA

Rocket Lab is an end-to-end space company delivering responsive launch services, complete spacecraft design and manufacturing, payloads, satellite components, and more - all with the goal of opening access to space. The rockets and satellites we build, and launch enable some of the most ambitious and vital space missions globally, supporting scientific exploration, Earth observation and missions to combat climate change, national security, and exciting new technology demonstrations.

Our Electron rocket has become the second most frequently launched U.S. rocket annually and has delivered more than 230 satellites to orbit, while we work to develop Neutron, our upcoming medium-lift, reusable launch vehicle for larger constellation deployment. Our Space Systems business designs and builds an extensive line of satellites, payloads, and their components, including spacecraft that have been selected to support NASA missions to the Moon and Mars and components used on the James Webb Space Telescope.

SPACE SYSTEMS

Rocket Lab's Space Systems team is responsible for every satellite and satellite component made by Rocket Lab: from complete satellites destined for missions to the Moon and Mars, to the individual components and subsystems that make up a satellite like solar panels, flight software, reaction wheels and star trackers, separation systems, radios, and more. Our Space Systems team is made up of engineers, technicians, and designers who design, create, and put together our own satellites for missions across the commercial, government, and defense sectors, or who build and assemble satellite hardware and software that supports other satellite missions.
