Mechanical Engineering Intern Fall 2026

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 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.

As a Mechanical Engineering Intern based at Rocket Lab’s site in Long Beach, California, you will have the opportunity to support the design, development, and integration of spacecraft hardware and flight harnessing across our Space Systems programs. You’ll contribute to concept creation, hardware build and test campaigns, and the delivery of fully qualified components for integration. This internship provides hands-on experience collaborating with multidisciplinary engineering teams and owning work from early design through spacecraft integration.

WHAT YOU’LL GET TO DO

• As an intern, you will work closely with your mentor and other employees within the department to apply your knowledge and grow your skills both technically and professionally

• Work with a fast-paced group of professionals to apply engineering and industry concepts to solve real challenges
