Job description

As a member of the CAD group at Apple, you will support gate-level glitch noise and static timing analysis methodologies to ensure the integrity of Apple silicon. This role involves learning and applying sign-off methodologies and production CAD flows while collaborating with senior engineers. You will work closely with CAD and physical design teams, assisting with tool qualifications and tapeout tasks. The position emphasizes innovation and the use of AI-driven workflows to enhance analysis across SOC designs.

Requirements

  • BS in Electrical Engineering, Computer Engineering, or related technical discipline and 10+ years of industry experience.
  • Hands-on experience with signal integrity analysis tools such as Tempus, PrimeTime-SI, ETS/Celtic, or equivalent.
  • Solid understanding of STA fundamentals and PrimeTime specifics including Tcl coding.
  • Strong Perl, Tcl, and/or Python scripting skills.
  • Working knowledge of crosstalk, OCV effects, and margins.

Responsibilities

  • Define and architect consistent noise and STA analysis methodology and drive deployment across multiple projects.
  • Own and drive flows and scripts for core gate-level noise and static timing analysis tools end to end.
  • Conduct deep root-cause analysis of noise violations and timing-path anomalies.
  • Serve as the technical authority for design and Physical Design teams on noise/timing constraint issues.
  • Drive noise and STA methodology improvements using AI coding agents.
  • Build infrastructure for large-scale noise/timing report mining and visualization.
  • Develop and support noise and timing ECO methodology and custom scripts for project tapeout.
  • Apply agentic diffing and summarization to accelerate tool and version qualification.
  • Create documentation, guidelines, and specs for internal AI assistants.
  • Mentor junior engineers on noise/STA analysis techniques and best practices.

Benefits

  • Employees at Apple are often offered comprehensive benefits that support physical and mental well-being—flexible medical plans, confidential counseling, onsite wellness centers at major campuses, and resources for fitness and daily life. Families typically receive fertility support, paid parental leave with gradual return, caregiving leave, and dependent-care guidance, while financial perks commonly include stock grants (with purchase discounts), 401(k) matching, and income-protection coverage. Employees also see robust time off, Apple University learning and tuition reimbursement, donation matching and paid volunteer hours, and deep product and partner discounts.
