Principal Development Engineer

Rocket Lab is a global leader in launch and space systems.

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 provided reliable access to orbit since 2018, becoming one of the most frequently launched rockets in the world.

Neutron will be our next rocket on the launch pad, an advanced 13-tonne payload class, reusable rocket to launch the mega constellations of the future.

Our space systems business includes our extensive line of satellites and components that have enabled more than 1,700 missions including the James Webb Space Telescope, NASA Psyche Mission, Artemis I, Mars Ingenuity helicopter, and more.Join our pioneering team and launch your career to new heights!

NEUTRONRocket Lab's Neutron team is responsible for bringing our new large rocket Neutron and its launch and test sites to life.

From designing and testing Neutron's structures and components, to firing up its new Archimedes engines, to setting up Neutron's launch pads and test sites across the United States, joining the Neutron team is your opportunity to help launch a new large rocket for the very first time.WHAT YOU'LL GET TO DORocket Lab seeks a Principal Development Engineer to help build the Neutron platform : Rocket Lab's medium lift, reusable launch vehicle capable of human spaceflight.

As a Principal Development Engineer, you work closely with structural analysts, designers, manufacturing engineers, and the prototyping team to develop and execute the design and certification strategy for mechanical structures and mechanisms across the Neutron launch vehicle.Development Engineers combine technical excellence with strengths in technical planning and communication.You will combine technical expertise in metallic materials with a general understanding of elastomers, and thermal protection systems.
