While other companies talk about it, we do it!
About the role
Rocket Lab seeks a Senior Thermofluids Analysis Engineer to help build the Neutron platform: Rocket Lab’s medium lift, reusable launch vehicle capable of human spaceflight.
As a Thermofluids Analyst in Rocket Lab’s Analysis team you will contribute to the analysis, design, validation, and improvements of subsystems on the Neutron launch vehicle. Day to day, you will be expected to process flight data to determine the environments experienced by vehicle components, demonstrate positive margins against these environments through detailed analysis, and set the requirements to validate this analysis through test.
Key Duties
Perform, validate, and document multiphysics analyses of launch vehicle systems and provide support for development projects, including:

Computational fluid dynamics (CFD) analysis of internal and external flows
Thermodynamic analysis of internal and external components
Aerothermal analysis for external heat loads
Multiphysics interaction, such as conjugated heat transfer (CHT), multiphase flow simulations, cryogenic propellant conditioning, ice build-up
Perform trade-off studies
System design and optimization, e.g. propellant management

Perform risk and failure analysis on a component and system level
Post-process and interpret ground and flight test data
Conduct reviews of analyses.
Work closely with design and test engineers to iterate through design concepts, determine test requirements, and demonstrate overall system performance.
Provide vision, technical leadership, and coordinate analysis resources
Ideal candidates will thrive in ambiguity, and are excited to work in a small, high performing team focused on continued learning and growth. Success in this position will be measured by the knowledge and experience you bring to the role, your ability to lead development projects without supervision, and your ability to successfully collaborate across teams to deliver results.
