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 to ensure the integrity of Apple silicon. You will work closely with senior engineers to learn and apply sign-off methodologies and production CAD flows. The position involves collaboration with CAD and physical design teams, contributing to tool qualifications, and gaining exposure to modern automation techniques. Your work will help enhance the robustness of designs across advanced technology nodes.

Requirements

  • BS in Electrical Engineering, Computer Engineering, or related technical discipline.
  • 3+ years of industry experience.
  • Background in gate-level signal integrity, with an emphasis on crosstalk glitch noise and static timing analysis (STA).
  • Hands-on experience with industry-standard SI and STA tools such as PrimeTime-SI or Tempus.
  • Scripting and automation skills in Python, Tcl, and/or Perl.

Responsibilities

  • Contribute to the development of sign-off methodologies, noise margins, and tool qualification strategies for gate-level glitch noise and static timing analysis (STA).
  • Develop and maintain production CAD flows and scripts for core noise and STA tools.
  • Support the glitch noise analysis approach, including thresholds and its impact on timing integrity.
  • Assist with root-cause analysis of crosstalk glitch and timing anomalies.
  • Collaborate with design and physical design teams on noise/timing constraints and flow issues.

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.
