Senior Flight Dynamics Engineer II

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.

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.

As a Senior Flight Dynamics Engineer II based out of Rocket Lab's site in Littleton, CO, you will perform tracking, navigation, maneuver, trajectory planning, and collision avoidance design and operations for Earth orbiting, lunar, and interplanetary missions as part of a dynamic team with subject matter experts from Systems, Ground Software, Electrical, Avionics, Flight Software, Thermal, Propulsion, and GNC engineering disciplines.

You will need to solve complex problems, at times under time critical conditions. Join a driven team of pioneers relentlessly tackling challenging projects, delivering on the impossible, and making an impact on the future of space!
