About the role

Key responsibilities & impact

Perform advanced thermo‑mechanical finite element simulations to evaluate stress, strain, deformation, and structural integrity of test sockets, thermal heads, interconnects, fixtures, handlers, and package interfaces
Lead warpage and deformation analysis for multi‑material assemblies, accounting for CTE mismatch, nonlinear material behavior, temperature gradients, and boundary conditions
Develop thermal cycling and mechanical fatigue models to predict long‑term reliability, including creep, stress relaxation, and interface degradation
Create process‑aware mechanical models capturing effects of assembly, cure, reflow, compression, press‑fit, and load‑path evolution through manufacturing and test
Translate package and test infrastructure requirements into mechanical design constraints and reliability metrics for early architecture decisions
Correlate simulation results with mechanical testing, thermal cycling data, warpage metrology, and strain measurements to validate and refine models
Identify mechanical risk drivers and recommend design, material, or process changes to improve robustness, manufacturability, and yield
Support root‑cause analysis of lab or field issues related to cracking, delamination, contact degradation, excessive warpage, or mechanical instability
Develop simulation methodologies, modeling guidelines, and best practices to improve consistency and prediction accuracy across programs
Partner closely with thermal, packaging, test, reliability, and manufacturing teams to ensure mechanical compatibility and system‑level alignment
Interface with external vendors and manufacturing partners on material selection, tolerances, and mechanical performance expectations
Document and communicate results through clear technical reports, design reviews, and executive‑level summaries
