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. 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. Our 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. We are currently seeking Senior Spacecraft Thermal Engineers I/II for future opportunities for our thermal engineering team based out of Long Beach. This team supports our Space System division and lead cutting-edge programs for civil, commercial, and defense customers. Spacecraft Thermal Engineers are responsible for overseeing the thermal design, analysis, testing, and validation of Rocket Lab's space vehicles. They are expected to perform thermal modeling and data analysis while working closely with the test and design engineers to capture the vehicle's thermal performance and provide input for design improvements. They support the Space Systems organization, with deliverables required for internal leadership, board of directors, and investors. (Please note: this position can be hired at the Senior Spacecraft Thermal Engineer I or Senior Spacecraft Thermal Engineer II level)
