Principal Flight Software Engineer

ABOUT ROCKET LAB Rocket Lab is the end-to-end space company building rockets, spacecraft, and critical subsystems that keep the world connected, protected, expand humanity’s reach to the Moon, Mars, and beyond. We move fast, build real hardware for meaningful missions, and make the impossible routine. Come shape the future with us. SPACE SYSTEMS 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. PRINCIPAL FLIGHT SOFTWARE ENGINEER Based out of Rocket Lab's global headquarters in Long Beach, CA, the Principal Flight Software Engineer will play a key role in supporting the development of flight software for our Space Systems programs. You’ll spend your days participating in all aspects of software design and development, from requirements definition through coding and testing. And when we say test, we mean your software will be on orbit within weeks and months, not years. Thanks to having our own rockets and launch sites, we have frequent opportunities to test and operate our software on orbit. This role is for someone who wants to see their software make a big impact on the way we explore space and use it as a platform for discovery and innovation.
