Job Summary Mechanical FEA Engineer Role. Run structural, shock/vibration, and warpage simulations for the module; report against Meta acceptance criteria and correlate to test data.

Key Responsibilities Responsibilities Static structural FEA — stiffener design iterations (rib layout, thickness, geometry, mounting locations, material) under mounting-pressure, gravity-sag and handling loads Shock and vibration (S&V) — random vibration, sine sweep and shock per transport and operational spec; verify modal separation and no fatigue or yield failure Staged warpage simulation — bare PCB, populated components and full PCBA, at room and high temperature;

flag SMT risk against package warpage contours Deliverables — analysis plans, meshed models, result fields and warpage contours, each with a pass/fail report against Meta acceptance criteria Test correlation — shadow-moiré for warpage; shaker and drop for S&VSkill Requirements Must-have 5+ years structural FEA in electronics, PCBA, or semiconductor packaging Ansys and/or Altair / Hyper Mesh (final toolchain TBC) PCB / PCBA warpage simulation — CTE mismatch, reflow- and assembly-induced, room and high temperature Shock / vibration and drop analysis;

modal and fatigue assessment Demonstrated test correlation — model versus measured, and closing the gap Able to execute defined load cases and report crisply against acceptance criteria

Nice-to-have Modeling board-to-board / supplier-to-supplier laminate variation — nominal models assume identical laminate data across suppliers, while real warpage varies significantly supplier to supplier; capturing that spread is a core capability Liquid-cooled module structures; cold-plate preload effects Advanced or composite stiffener materials Scripting for parametric sweeps (Python / APDL)
