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 Spacecraft Propulsion Test Engineer II on our propulsion engineering team based out of Long Beach, CA, your purpose will be to plan, prepare for, and execute engine and propulsion component testing. This includes ownership of the test facility, equipment, and test operations. You will play a critical role in successful development, qualification, and production testing, which directly results in the success of our missions and products.

As part of the propulsion development team, you will be involved with engine and propulsion system development from cradle-to-grave, providing test-driven insights that improve the reliability, manufacturability, testability, and performance of our products.
