Job responsibilities

  • Own and maintain the top-level Global Finite Element Model (GFEM): set and enforce standards for material properties, numbering, interfaces, model fidelity, and validation procedures.
  • Produce rapid analysis studies and design guidance: perform hand calculations and create lightweight beam/shell FEMs to drive design trades;
  • Structural sizing and certification support: perform static, dynamic, stability, and damage-tolerance analyses for metallic and composite primary/secondary structures;
  • Test planning and correlation: define pre-test predictions, instrumentation plans, and post-test correlation workflows;
  • Failure investigation and corrective actions: lead root-cause investigations for test and field failures, generate corrective design changes, and work with manufacturing, design, reliability, and test teams to close…
  • Cross-functional ownership and tooling: collaborate daily with design, systems, reliability, test, and flight operations;
  • Field and flight-test support: support flight-test campaigns and field remediation events on-site, execute rapid test fixes, and prioritize fleet-impacting issues to minimize downtime and preserve flight schedules.
  • Measurable outcomes you will be accountable for: reduction in product level cost per delivery, GFEM release cadence (e.g., weekly/monthly to match config updates), reduction in structural repeat failures across fleet,…
