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 FEM,CFD,  and data analysis whilst 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 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)
  • Perform heat transfer simulations (conduction, convection and radiation)
  • Post-process and interpret static and dynamic ground test and flight data.
  • Perform, validate, and document CFD analyses of launch vehicle fluid systems including
    • Compressible flow (choked flow, two phase flow)
    • Incompressible flow
  • 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+ years industry experience, ideally from the Aerospace, Automotive or Marine industries.
  • 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
  • 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 (accelerometers, strain gauges, thermocouples etc.)
  • Familiarity with manufacturing processes, including conventional machining, and additive manufacturing
  • 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 one or more industry standard CFD packages: Fluent, CFX, STAR-CCM+.
  • Experience in structural analysis of composites (laminate design, joint design, materials characterization, environmental effects).
  • Familiarity with the manufacture of composite materials (prepreg autoclave and OOA).
  • Experience in linear and non-linear buckling (particularly shell buckling)
  • Familiarity with non-linear material simulation, including metal plasticity, elastomers, and adhesive joints.
  • Experience with vibroacoustic modelling/analysis.
  • Familiarity with industry standards (e.g. MIL-STD-1540, GSFC-STD-7000, ECSS-E-HB-32, NASA-STD-5001).
  • Experience with static and dynamic structural test methods experimental modal analysis, shaker table testing)
