Thermal Mechanical Modeling Engineer

Own and execute hands-on semiconductor package mechanical and thermal simulations for advanced 2.5D/3.0D heterogeneous integration and multi-material packages.Perform modeling, extraction, and verification of high-speed interconnects, power delivery networks, thermal management, and mechanical stress across chiplets and advanced substrates.Build and validate comprehensive ADK/PDK models (electrical, EM, thermal, mechanical) that accurately represent package-level behavior and enable system-level co-design.Run end-to-end simulation workflows including thermal/structural reliability checks, and co-simulation across domains.Collaborate directly with EDA vendors (Cadence, Ansys, Synopsys, Siemens, Keysight, etc.), OSATs, and foundries to develop, test, and refine package simulation flows.Generate user guides, reference flows, scripts, and automation that make SI/PI/multiphysics enablement repeatable and accessible to design teams.Stay current with next-gen interface standards (PCIe Gen6/7, CXL, UCIe, UALink, SerDes, HBM) and incorporate their requirements into package design methodologies.Guide technical strategy for SI/PI flows, mentor junior engineers, and represent TIE in working groups, customer design reviews, and industry forums.Other related functions as assigned.
