Job Description Insight Global is looking for a Senior / Principal TCAD Modeling Engineer that will be working on site in Austin, TX and support a public-private partnership of preeminent semiconductor systems and defense electronics companies, national labs, and academic institutions. Their mission is to advance the state-of-the-art in critical semiconductor domains such as advanced packaging, and in the process to help restore U.S. leadership in semiconductor manufacturing. They are developing cutting-edge semiconductor manufacturing equipment and processes that will define future roadmaps of semiconductor logic, memory, heterogenous integration, chip cooling, etc. They are Backed by $1.4 billion in combined funding from DARPA, Texas state initiatives, and strategic partners, they are building foundational capabilities in advanced packaging and integrated design infrastructure to restore U.S. leadership in microelectronics manufacturing. 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 device, 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 the device and interface platforms. We are a company committed to creating diverse and inclusive environments where people can bring their full, authentic selves to work every day. We are an equal opportunity/affirmative action employer that believes everyone matters.
