Job description

In this role at Apple, you will be part of the CAD group, focusing on gate-level glitch noise and static timing analysis methodologies for Apple silicon. You will work closely with CAD and physical design teams to ensure signal integrity and robustness across advanced technology nodes. The position involves applying sign-off methodologies and utilizing industry-standard tools under the guidance of senior engineers. Your contributions will enhance the analysis processes and methodologies, leveraging AI-driven workflows to improve efficiency and accuracy.

Requirements

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

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 and timing issues.
  • Drive noise and STA methodology improvements using AI coding agents.

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.
