Purpose This role is to lead and execute comprehensive thermal and mechanical simulations for advanced 2.5D/3.0D heterogeneous integration and multi-material packages. The position will also collaborate with EDA vendors, OSATs, and foundries, and stay current with next-gen interface standards to guide technical strategy and mentor junior engineers.

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. • Other related functions as assigned.

Required Qualifications

Engineer: • 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. • Location. Austin, Texas is required for close collaboration with our engineering teams and partners.

Senior Engineer: • MS or PhD in Electrical Engineering, Applied Physics, or related discipline. • 5 or more years of direct, hands-on experience in multiphysics simulations for advanced packaging, 2.5D/3DIC, or heterogeneous integration platforms. • Deep experience with multi-material packages (Si, glass, o
