Senior Software Engineer III Simulation Engineering

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 rockethas 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.

SPACE SYSTEMS

At Rocket Lab were not just launching rockets were 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 1700 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 its 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.

SENIOR SOFTWARE ENGINEER I/II SIMULATION ENGINEERING

We are seeking a highly skilled and experienced Senior Software Engineer I/II Simulation Engineering to join our team based out of our Littleton CO site. In this role you will focus on architecting large-scale simulation environments and driving high-level data analysis to solve complex aerospace challenges.

WHAT TO EXPECT

Were on a mission to unlock the potential of space to improve life on Earth but thats 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 others 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.
