We move fast, build real hardware for meaningful missions, and make the impossible routine. Come shape the future with us.\nSPACE SYSTEMS \n 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, precision payloads to the components and subsystems that allow them to thrive in space, like solar panels, flight software, star trackers, optical systems, separation systems, radios, and more. \nOur Space Systems team has enabled more than 1,700 missions, ranging from interplanetary exploration, 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, 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. \nSENIOR OPTOMECHANICAL ENGINEER I/II\nBased on site at Rocket Lab Robotics in Pasadena, CA, the Senior Optomechanical Engineer I/II i s responsible for leading mechanical design efforts for optical payloads, camera systems, precision mechanisms, sensor assemblies, tooling, fixtures, ground support equipment, and electromechanical hardware.
