Ground Systems Engineer II/Senior - Fluids

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 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

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!
