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 worldwide, supporting scientific exploration, Earth observation, climate‑action initiatives, national security, and cutting‑edge 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. The Space Systems team designs and builds an extensive line of satellites, payloads, and their components, including spacecraft selected to support NASA missions to the Moon and Mars and components used on the James Webb Space Telescope.

Senior Spacecraft Guidance, Navigation and Control (GNC) Engineer I Based at Rocket Lab’s global headquarters in Long Beach, CA, the Senior Spacecraft GNC Engineer I is responsible for leading GNC and ADCS development for our growing fleet of diverse spacecraft. You will demonstrate a firm grasp of spacecraft GNC concepts and applications and work with all facets of the engineering life cycle: spacecraft concept and algorithm development, flight software implementation, subsystem requirements development, detailed GNC design, subsystem integration & test (I&T) and vehicle I&T. You will plan and maintain the development schedule to support the Space Systems Software organization in executing leading‑edge programs and products. You will work closely with related teams, including Systems, Avionics, Flight Software, Mission Operations and Ground Software, and directly interact with customers to ensure mission success.

WHAT TO EXPECT We’re on a mission to unlock the potential of space to improve life on Earth, but that’s not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out‑think, out‑work and out‑pace. We pride ourselves on having each other’s backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small. We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.
