Senior Flight Software Engineer - Neutron

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 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. While other companies talk about it, we do it! NEUTRON Rocket 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. SENIOR FLIGHT SOFTWARE ENGINEER – NEUTRON As a Senior Flight Software Engineer based at Rocket Lab’s Auckland, New Zealand site, you will support the development of the next‑generation Command Data Handling system for the Neutron launch vehicle. In this role, you will work across the full software stack to build core flight software, simulation frameworks, and development tools that enable mission‑critical applications. To be successful, you must be a proactive problem‑solver with strong technical judgment, a collaborative mindset, and a passion for building reliable systems that fly.
