About The Role

As a Propulsion Analyst in Rocket Lab’s Analysis team you will contribute to the analysis, design validation, and future improvements of all propulsion systems on the Electron launch vehicle.  

Day to day you will be expected to perform CFD, FEM, and data analysis whilst also working closely with the propulsion,  test, and design engineers to capture the vehicle’s performance and provide input for design improvements.
  
Key responsibilities will include:
  • Perform, validate, and document CFD analyses of launch vehicle fluid systems including
    • Compressible flow (choked flow, two phase flow)
    • Incompressible flow
  • Perform heat transfer simulations (conduction, convection and radiation)
  • Perform, validate, and document structural analyses of primary and secondary launch vehicle structures, including
    • Finite element analysis
    • Material selection
    • Performance trade-off studies
    • Mass optimization
  • Perform dynamic simulations (modal, random vibration, transient)
  • Post-process and interpret static and dynamic ground test and flight data
  • Conduct peer reviews of analyses
  • Work closely with design and test engineers to iterate through design concepts, determine test requirements, and demonstrate positive structural margins

What you’ll bring to Rocket Lab:
  • A bachelor's degree in Mechanical Engineering or equivalent qualification
  • 5+ year’s industry experience, ideally from the Aerospace, Automotive or Marine industries
  • Demonstrated expertise with one or more industry standard CFD packages: Fluent, CFX, STAR-CCM+
  • Experience with heat transfer mechanisms, including conjugate heat transfer simulations
  • Experience in pump design and analysis
  • Experience with mechanical systems in a relevant field (e.g. aerospace, automotive, marine)
  • Experience using Solidworks CAD and PDM packages (or comparable industry standard packages) with emphasis on model interrogation and defeaturing for subsequent analyses.
  • Experience with experimental test methods, sensor selection and data post-processing/ interpretation
  • The ability to work to deadlines within a high pressure environment
  • Proven communication skills and the ability to build strong working relationships with colleagues and engineering professionals
Desirable Skills:
  • Demonstrated expertise with combustion modeling and rocket engine design
  • Demonstrated expertise with one or more industry standard structural FEA packages: ANSYS, Abaqus, Nastran, Optistruct/Hyperworks
  • Demonstrated expertise in accurate prediction of component life and structural margins, including:
    • Ductile metal failure
    • Fatigue
    • Fracture
  • Familiarity with non-linear material simulation, including metal plasticity, elastomers, and adhesive joints
  • Familiarity with manufacturing processes, including conventional machining, and additive manufacturing
  • Familiarity with industry standards (e.g. MIL-STD-1540, GSFC-STD-7000, ECSS-E-HB-32, NASA-STD-5001)
  • Experience with vibroacoustic modelling/analysis.

What’s in for you?
We'll offer you a career-defining role, interesting and meaningful projects working with world leading experts.  You will lead, inspire and support team members to reach their potential and deliver on our mission to open access to space to improve life on Earth.  Based at our new state of the art facility in Mt Wellington, Auckland, this comes with a range of staff benefits in including subsidised lunches and an on-site gym.
