Mechanical Technician II

SPACE SYSTEMS

At Rocket Lab, we’re not just launching rockets — we're building the future of space. Our Space Systems team builds everything from complete spacecraft and precision payloads to the components and subsystems that allow them to thrive in space, such as solar panels, flight software, star trackers, optical systems, separation systems, radios, and more. Our Space Systems team has enabled more than 1,700 missions, ranging from interplanetary exploration and in‑space manufacturing to national security and defense initiatives.

The team has built spacecraft, payloads, and components for missions to the Moon and Mars, working with partners including NASA, the Space Development Agency, and the U.S. Space Force. Whether it’s a single high‑performance spacecraft, a constellation, or the vertically integrated components that help them get to space — our world‑class Space Systems team is empowering some of the boldest and most ambitious space missions.

Based out of Rocket Lab’s site in Toronto, Ontario, the Mechanical Technician II will be responsible for the integration of spacecraft precision attitude determination and control products, which are comprised of mechanical, electrical, and optical subassemblies. The successful candidate will assemble, inspect, and perform other duties associated with building products from Rocket Lab’s star tracker and reaction wheel product lines. Join a driven team of pioneers relentlessly tackling challenging projects, delivering on the impossible, and making an impact on the future of space!
