About the role

Key responsibilities & impact

Perform advanced finite element analysis (FEA) to evaluate thermomechanical reliability of ASIC packages and board-level assemblies
Lead solder joint reliability simulations, including thermal cycling, mechanical shock, and vibration
Develop lifetime prediction models based on industry methodologies (e.g., Coffin-Manson, Darveaux)
Model and analyze time-dependent material behavior, including creep, viscoplasticity, and fatigue
Drive board-level reliability (BLR) assessments, including PCB–package interactions and SMT effects
Correlate simulation results with reliability testing data to improve model accuracy
Develop and automate simulation workflows using Python, Fortran, or similar tools
Provide design recommendations and reliability sign-off guidance to cross-functional teams
Document methodologies, assumptions, and results clearly to support engineering reviews
