Responsibilities
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

Qualification
Required
BS in Electrical Engineering, Computer Engineering, Applied Physics, or related discipline
3 or more years of direct, hands-on experience in multiphysics simulations for advanced packaging, 2.5D/3DIC, or heterogeneous integration platforms
Strong expertise with EDA/EM/multiphysics tools: Ansys HFSS/SIwave, Cadence Sigrity/Clarity, Synopsys RaptorX, Siemens HyperLynx, Keysight ADS, COMSOL, CST Studio
Proven ability to extract/package-level models (dielectric/thermal constants, warpage/stress data) and integrate them into design enablement flows
Hands-on scripting/automation skills (Python, Tcl, SKILL, etc.) to streamline simulation flows
You're energized by ambiguity, act with urgency, and take personal ownership for outcomes. You make things happen
Execution mindset. You have demonstrated experience working in a hands-on role driving progress across multiple initiatives without layers of management
