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.

What you'll do

• Propellant Own propellant delivery and management—covering temperatures and: stratification, cavitation margin, transients, slosh, PMD design, settling, and in-space thermodynamics—and perform CFD of internal fluid systems (compressible and incompressible flow)

• Address depletion, residuals, and utilisation control, and own tank: pressurisation, including pressurant budgets, in-tank thermodynamics, and autogenous system sizing

• Design RCS systems, including N2 budget, thruster specification, and flow modelling of valves and lines

• Thermal Own system thermal design across ground, flight, and in-space: operations, including TPS response, compartment thermals, insulation, and component thermal modelling

• Perform heat transfer simulations (conduction, convection, radiation) and: characterise thermal environments, developing design guidelines and mitigations

• Model HVAC and cavity conditioning (flow/temperature specification, pressure: drop, flammability, cleanliness, humidity) and support payload integration and customer ITAs

What they're looking for

• Analysis & Data Work closely with design and test engineers to iterate: design concepts, determine test requirements, and demonstrate positive margins through numerical analysis, and physical test
• Process and interpret ground test and flight data—confirming MPE bounds,: detecting out-of-family results, and resolving sensor configuration issues
• A degree in Mechanical or Aerospace Engineering or similar field
• + years industry experience, ideally from the Aerospace, Automotive, or Marine industries
