Principal Optical Engineer

About Rocket Lab

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 is 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 selected to support NASA missions to the Moon and Mars and components used on the James Webb Space Telescope.

Rocket Lab’s Optical Systems division solves mission‑critical space‑domain and Intelligence, Surveillance, and Reconnaissance (ISR) challenges for Department of Defense (DoD) and Intelligence Community (IC) customers. As a Principal Optical Engineer based at our Optical Systems site in Tucson, AZ, you will play a key role in the modelling, simulation, prototyping, and characterization of advanced EO/IR payloads that support national defense space missions.
