Software Engineering Director/Architect, 3DIC P&R & AI-driven EDA Automation

Cadence Design Systems•Austin, TX

About The Position

At Cadence, we hire and develop leaders and innovators who want to make an impact on the world of technology. We are looking for a Software Engineer to help build scalable EDA flows and AI-driven automation for advanced 3DIC applications. This role will focus on developing robust flow-generation capabilities, debugging assistance, root-cause analysis, and platform integration for 3DIC, interposer, and RDL system flows.

Requirements

Strong background in EDA data structures and algorithms.
Hands-on experience with Tcl, Python, and C++ automation in EDA tools.
Experience with DB-driven design flows, such as Innovus or similar implementation platforms.
Understanding of 3DIC, interposer, packaging routing, and RDL design flows.
Knowledge of constraint-driven design, including timing, signal integrity, DRC, and related implementation constraints.
Experience handling large-scale design problems, including high bump-count designs and multi-region routing challenges.

Nice To Haves

Experience with 3DIC, 3.5D, or 2.5D designs.
Familiarity with signal integrity, EMIR, and thermal considerations in advanced packaging environments.
Experience with LLM or AI systems, including agent frameworks and prompt-to-script automation.
Knowledge of multi-tool integration and end-to-end flow automation.
Ability to translate complex EDA workflows into scalable, user-friendly automation solutions.

Responsibilities

Build scalable EDA flows using C++, Tcl, Python, and Java.
Develop AI/LLM-based automation for 3DIC applications, including flow generation, debugging assistants, and root-cause analysis capabilities.
Integrate 3DIC flows into a broader platform system supporting 3DIC, interposer, and RDL system flows.
Design and automate workflows that improve usability, productivity, and debug efficiency for complex package and system-level design challenges.
Collaborate with cross-functional engineering teams to define requirements, validate flow behavior, and deliver production-quality solutions.
