About The Role

Rocket Lab is looking for a structural engineer to join our expanding team of engineers working on the Electron Launch Vehicle.   This is an opportunity to be part of the most exciting engineering project currently being undertaken in New Zealand.

Rocket Lab’s launch cadence will rapidly increase over the coming years, reaching 50-100 launches per year, which will increase the amount of mission and customer related structural analyses. Therefore, we are looking for an experienced coupled loads analysis (CLA) engineer. 

Key duties include
  • Perform coupled loads analyses (CLA) for customer payloads on the Electron launch vehicle, which includes a range of dynamic simulations, e.g. modal, random vibration, transient
  • Validate and improve the current CLA model, e.g. perform flight data comparisons, additional load case development
  • Design and analyse mission specific payload support structures
  • Post-process and interpret CLA results
  • Generate CLA reports
  • Support customers with their finite element (FE) model development, setup and verification. Furthermore, support and advise customers regarding their structural test procedures, test setup and data interpretation
  • Work closely with mission management, analysis and test engineers to iterate through design concepts, determine test requirements, and demonstrate positive structural margins

Essential Skills required
  • 3+ years’ relevant experience
  • Demonstrated expertise with one or more industry standard structural FEA packages: ANSYS, Abaqus, Nastran, Optistruct/Hyperworks
  • Demonstrate expertise in coupled loads analyses (CLA) from a launch provider or customer perspective, and show familiarity with Craig-Bampton method and superelements
  • Demonstrated expertise in modelling and accurately predicting structural load cases relevant to launch operations, e.g. events that include ignition, hold‐down release, and engine shut‐down transients; in‐flight dynamics driven by aerodynamic loading and thrust vector control actuations; steady state structure‐borne vibration from transportation and flight loads; and high frequency excitations from shock and acoustics
  • Ability to present CLA results in a structured and concise manner
  • Experience with mechanical systems in a relevant field (e.g. aerospace, automotive, marine)

Desirable skills
  • Experience using Solidworks CAD and PDM packages (or comparable industry standard packages) with emphasis on model interrogation and defeaturing for subsequent analyses
  • Experience in structural analysis of composites
  • 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 (strain gauges, accelerometers, experimental modal analysis, shaker table testing)

For security reasons background checks will be undertaken prior to any employment offers being made to an applicant.  These checks will include nationality checks as it is a requirement of this position that you be eligible to access equipment and data regulated by the United States’ International Traffic in Arms Regulations.  Under these Regulations, you may be ineligible for this role if you do not hold citizenship of Australia, Japan, New Zealand, Switzerland, the European Union or a country that is part of NATO, or if you hold ineligible dual citizenship or nationality. For more information on these Regulations, click here.
