Senior Ground Systems Engineer - Mechanical

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. Rocket Lab is a global leader in space systems, and we’re looking for a Senior Ground Systems Engineer - Mechanical to join our innovative team. In this role, you’ll design, build, test, and commission the critical systems that support our Electron and Neutron launch vehicles- from production to orbit. If you’re ready to push the boundaries of engineering in a fast-paced, cutting-edge environment, this is your opportunity to make an impact. ABOUT THE ROLE: As a Senior Ground Systems Engineer - Mechanical, you’ll be a subject matter expert and technical decision-maker, responsible for the design and development of launch range and test cell structures, mechanisms, and fluid systems. You’ll work on systems that operate in high-vibration, harsh, and hazardous environments, ensuring they meet the rigorous demands of space exploration. This role is hands-on and collaborative, requiring you to work closely with suppliers, technicians, and cross-functional teams to deliver world-class solutions. From concept to commissioning, you’ll play a key role in ensuring Rocket Lab’s ground systems are reliable, efficient, and ready to support our missions. WHAT YOU'LL DO: Design & Development Design systems such as launch vehicle transporters, erectors, launchers, spacecraft handling equipment, and ground support tooling. Develop fluid systems, including cryogenics, with a focus on safety and efficiency. Perform structural design and analysis for high-vibration and hazardous environments. Create 2D and 3D models using CAD software (SolidWorks, NX). Conduct system sizing and analysis using hand calculations and numerical methods. Develop and maintain Bills of Materials (BOMs) and interface control documentation. Collaborate with suppliers and internal teams to ensure designs meet specifications. Operations Support Work closely with test and operations teams to ensure systems are operational and meet mission requirements. Support pad technicians during installation, commissioning, testing, and troubleshooting activities—both remotely and on-site. Develop and execute test plans to validate system performance and vehicle interfaces. Design, develop, and maintain test equipment for ground systems. Analyse post-flight and post-test data to identify improvements. Project Management Lead projects for facility and system builds, ensuring they are delivered on time and within budget. Support certification of launch pad systems and develop maintenance programs. Identify risks and implement mitigation strategies to ensure project success.
