About the role

Signoff Engineer in Apple’s Silicon Technologies group focused on verification and analysis of mixed-signal designs prior to tapeout, applying power/EMIR analysis and signoff methodologies at gate and transistor levels, with evolving AI/ML/LMM-driven techniques to accelerate analysis and flow debugging.

Responsibilities

  • Develop, define, and refine signoff methodologies for mixed-signal designs at gate and transistor levels
  • Perform functional static/dynamic IR analysis, scan-mode IVD analysis, and power/EM analysis
  • Handle package model handling, signal EM, power switch modeling, and IP reuse in signoff
  • Define signoff requirements early in project lifecycle and ensure signoff criteria are met by project close
  • Collaborate with Design, CAD, and Technology teams to confirm EDA flows and tools are properly set up
  • Provide frontline enablement, enhancement, and debugging support to design groups
  • Explore AI/ML/LLM-driven techniques to accelerate analysis and surface anomalies earlier in the design cycle

Qualifications

  • Minimum requirement of BS and 10+ 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 transistor and gate level across static and dynamic modes
  • In-depth knowledge of Redhawk, Voltus, and Totem
  • Experience in simulation and power analysis to verify circuit performance
  • Strong understanding of CAD flows
  • Proficiency in Perl and Python scripting/programming
  • 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
