Senior Package Modeling Engineer

NVIDIA NVIDIA · Semiconductors · Santa Clara, CA

This role focuses on Finite Element Analysis (FEA) for semiconductor package development, assessing stress, warpage, and thermo-mechanical behavior. The engineer will contribute to packaging technology roadmaps, evaluate new materials and processes, analyze material properties' impact on reliability, and establish modeling approaches. Collaboration with cross-functional teams and documentation of findings are key responsibilities. The role requires expertise in FEA tools, understanding of thermal-mechanical interactions, reliability failure modes, and advanced semiconductor packaging architecture.

What you'd actually do

  1. Conduct Finite Element Analysis (FEA) to assess stress, warpage, and thermo-mechanical behavior throughout advanced semiconductor packaging platforms.
  2. Contribute to packaging technology direction and long‑term roadmaps by evaluating new materials, interconnect concepts, and process options with a focus on structural robustness and reliability.
  3. Analyze material properties and their impact on package reliability.
  4. Establish modeling approaches and assumptions, interpret simulation results, and provide practical mentorship that influences package build, material selection, and manufacturing processes.
  5. Collaborate with cross-functional teams to ensure robust package builds.

Skills

Required
