Fluid Systems 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.

NEUTRON

Rocket Lab’s Neutron team is responsible for bringing our new large rocket Neutron and its launch and test sites to life. From designing and testing Neutron’s structures and components, to firing up its new Archimedes engines, to setting up Neutron’s launch pads and test sites across the United States, joining the Neutron team is your opportunity to help launch a new large rocket for the very first time.

STAGE FLUIDS ENGINEER II

A Stage Fluids Engineer II owns the design, build, and test of their fluid systems across the Neutron launch vehicle. Our team owns all plumbing and fluid systems between the tanks and the engines. Your work within the Fluid Systems department will turn vehicle-level requirements into a fluid network that enables Neutron to operate with aircraft-like reusability and reliability.

WHAT YOU’LL GET TO DO:

• Design plumbing systems, components, and their secondary structures.
• Analyze these systems and components in the harsh and dynamic environments of launch.
• Model these systems to characterize and predict system behavior at all conditions.
• Test and qualify these systems and components.
• Manage requirements, realization, and implementation of systems in the larger launch vehicle context.
• Integrate your hardware into the vehicle.
• Review data from component, system, and vehicle level testing to optimize and improve future designs.
• Collaborate with components, propulsion, structures, mechanical, operations, and flight software teams to develop and define vehicle functions.
• Create tools to enhance the team’s analysis capabilities, streamline workflow and optimize launch operations.

YOU’LL BRING THESE

QUALIFICATIONS:

• Bachelor’s degree in Mechanical Engineering or relevant engineering discipline.
• 2+ years of experience in a hardware rich environment.
