Full Job Description
Description

As a Signoff Engineer, you'll ensure that all necessary verification and analysis work is completed on complex mixed-signal designs prior to tapeout. In this highly visible role on our advanced Signoff CAD team, you'll work on state-of-the-art designs and apply hands-on experience in power/EMIR analysis to develop, define, and refine signoff methodologies at both the gate and transistor level. This includes, but isn't limited to, signoff for functional static/dynamic IR analysis, scan-mode IVD analysis, package model handling, power EM analysis, signal EM, power switch modeling, and IP reuse. Our team is also evolving how we approach signoff itself - increasingly exploring AI/ML and LLM-driven techniques to accelerate analysis, automate flow debugging, and surface anomalies earlier in the design cycle.

You'll help define signoff requirements early in the project lifecycle, partner with Design, CAD, and Technology teams to confirm EDA flows and tools are set up and running correctly, and ensure all signoff criteria are met by project close. You'll also interface directly with design groups, providing frontline support for enablement, enhancement, and debug requests.
