Partners across teams and external vendors co-optimize designs, set modeling best practices, deliver reusable reference flows, and mentor engineers.

Requirements

Ph.D. or M.S. in Electrical Engineering, Materials Science, Applied Physics, or a closely related field with strong emphasis on device physics and numerical simulation.
8+ years (Senior) or 12+ years (Principal) of hands-on experience with TCAD for semiconductor devices or interconnects.
Deep understanding of semiconductor device physics (MOSFETs, diodes, contacts) and transport mechanisms relevant to nanoscale and 3D structures.
Proficiency with commercial TCAD tools such as Synopsys Sentaurus, Silvaco Atlas/Victory, or equivalent multi-physics simulation environments.
Experience correlating TCAD models with silicon data and extracting physical parameters from measurements.
Strong background in process integration effects (doping, defects, interfaces, stress, and materials).
Ability to work cross-functionally with process, packaging, EDA, and system teams in a fast-moving R&D environment.
Relevant education and experience may be substituted as appropriate.

Nice To Haves

Experience modeling 3D integration features such as hybrid bonding interfaces, TSVs, or wafer-to-wafer/die-to-wafer stacks.
Familiarity with reliability physics (electromigration, TDDB, stress migration, thermal cycling) in advanced interconnects or contacts.
Exposure to advanced materials systems (Cu-Cu bonding, barrier/liner stacks, low-k dielectrics, compound semiconductors).
Knowledge of compact model extraction and linkage between TCAD and SPICE-level models.
Publication or patent record in semiconductor device modeling, interconnect physics, or advanced packaging.
Strong technical writing and presentation skills for industry and defense-sector collaborations.

Responsibilities

Develop and own TCAD modeling frameworks for advanced devices and interfaces relevant to 3DHI, including hybrid bonding contacts, TSVs, BEOL interconnects, and emerging device structures.
Perform multi-physics simulations (electrical, thermal, mechanical, and reliability) to predict performance, variability, and failure mechanisms across stacked, heterogeneous die systems.
Co-optimize devices, interconnect, and packaging designs by working closely with process integration, packaging, and circuit teams to close the loop between fabrication, measurement, and simulation.
Calibrate and validate TCAD models using silicon data from wafer-level test vehicles and process monitors; drive model-to-hardware correlation across corners and stress conditions.
Define simulation methodologies and best practices for 3D device and interface modeling (e.g., contact resistance, current crowding, electromigration, thermo-mechanical stress).
Engage with foundry, EDA, and materials partners to influence next-generation TCAD tool features and process design enablement for 3D-stacked systems.
Author technical documentation, modeling guidelines, and reference flows to support ecosystem adoption of TIE’s device and interface platforms.
Mentor junior engineers and technical staff, setting standards for modeling rigor and engineering judgment across the organization.
