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 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 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. 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.

Rocket Lab is on a mission to redefine space exploration, and we’re looking for a Development Engineer I to join our In-Space Propulsion (ISP) Team. If you’re passionate about solving tough engineering challenges, working hands-on with cutting-edge technology, and contributing to groundbreaking missions like NASA’s ESCAPADE to Mars, this is your chance to make an impact.

ABOUT THE TEAM:

The ISP team is at the forefront of developing and delivering flight-ready propulsion systems for space vehicles. From system-level ownership to component-level innovation, we design, build, and test propulsion systems that power humanity’s exploration of the cosmos.

Our past successes include the Curie and HyperCurie engines, and we’re currently developing the propulsion system for ESCAPADE, a NASA mission to Mars. Collaboration is key, and we work closely with teams across Rocket Lab, including GNC, Manufacturing Engineering, Flight Software, and more.

ABOUT THE ROLE:

As a Development Engineer I, you’ll play a critical role in the upkeep and development of spacecraft propulsion systems. You’ll work alongside talented engineers, technicians, and analysts to deliver high-quality products that meet mission requirements. From hands-on testing to detailed design work, you’ll be involved in every stage of the development lifecycle.

WHAT YOU’LL DO:

Own the propulsion design, engineering BOM, manufacturing communication, testing requirements, and lifecycle maintenance of propulsion systems.
Build, test, and integrate sensitive hardware alongside technicians and engineers.
Interface with cross-functional teams to ensure seamless integration and operation of propulsion systems.
Create and review technical documents, ensuring accuracy and clarity.
Plan and execute long-term projects, raising support requests and escalating blockers as needed.
Identify risks, escalate appropriately, and contribute to mitigation strategies.

WHAT WE’RE LOOKING FOR:

Essential Skills & Experience:

Strong sense of ownership and rigorous thinking
Curiosity and eagerness to learn
Excellent grasp of mechanical engineering fundamentals
Hands-on experience building or testing mechanical or electromechanical components/systems
Proven track record of delivering successful engineering projects from conception to operation
1+ years of industry experience
Engineering degree
