About the role

Signoff Engineer in Apple’s Silicon Technologies group responsible for verification and analysis of complex mixed-signal designs prior to tapeout, focusing on power/EMIR analysis and signoff methodologies at gate and transistor levels, with opportunities to apply AI/ML and LLM-driven techniques to accelerate analysis and debugging.

Responsibilities

  • Ensure verification and analysis work is completed on complex mixed-signal designs prior to tapeout.
  • Define, refine signoff methodologies at gate and transistor levels.
  • Perform 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.
  • Evolve signoff approaches and apply AI/ML/LLM-driven techniques to accelerate analysis, automate flow debugging, and surface anomalies earlier in the design cycle.
  • 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.
  • Ensure all signoff criteria are met by project close.
  • Interface directly with design groups to provide enablement, enhancement, and debug support.

Qualifications

  • Minimum requirement of BS and 3+ years of relevant industry experience
  • Experience in CAD, EMIR analysis, or related circuit design roles
  • Solid understanding of circuit design principles and EMIR analysis at the transistor and gate level across static and dynamic modes
  • In-depth knowledge of tools such as Redhawk, Voltus, and Totem
  • Experience in simulation and power analysis to verify circuit performance
  • Strong understanding of CAD flows
  • Proficiency in scripting/programming languages (Perl and Python)
  • Excellent communication and collaboration skills
  • Experience developing CMOS analog and mixed-signal designs
  • Experience applying AI/ML or LLM-based tools to EDA flow automation, anomaly detection, or signoff data analysis
