Test Technician III - C Shift

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, all while we work to develop Neutron, our upcoming medium‑lift, reusable launch vehicle for larger constellation deployment. Our Space Systems business designs and builds our 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.

Neutron is a medium lift launch vehicle capable of delivering the mega constellations of tomorrow, high assurance payloads, and human spaceflight. As a highly reusable launch platform, Neutron will deliver a highly cost‑effective and reliable launch solution leveraging Rocket Lab’s proven execution history with the Electron program. If you’re interested in joining a high performing team, pushing the boundaries with a clean sheet development of re‑usable liquid launch vehicle, this is your opportunity!

Based out of Rocket Lab’s Headquarters in Long Beach, CA, the Test Technician III is responsible for the testing of our Rutherford rocket engine. The engine consists of a thrust chamber, pumps, valves, plumbing, TVC actuators, motor controllers, and other mechanical components. You will support the Propulsion Production Manager and production organization, with deliverables required for internal leadership, board of directors, and investors.
