Job description

In this role as a member of the STA CAD team, you will play a crucial part in enhancing the performance of Apple Silicon. You will focus on static timing methodologies and address timing challenges on advanced technology nodes. Your work will involve developing and maintaining gate-level STA flows and collaborating with design teams to resolve issues related to timing closure. This position requires a strong understanding of timing analysis and the ability to drive methodology improvements across various teams.

Requirements

  • Minimum requirement of a BS degree and 10 years of relevant industry experience.
  • Expert power user of static timing analysis tools and flows.
  • Advanced programming skills with Python and Tcl or other high-level programming languages.
  • Proven track record of development and deployment of complex CAD flows and automation.
  • Familiarity with STA of large high-performance SoC designs in deep sub-micron technologies.
  • Deep understanding of noise, cross-talk, variation, margins, and timing models.
  • Knowledge of timing/SDC constraints with hands-on experience in creation and validation of constraints.
  • Excellent communication skills to accurately assess and describe issues to management.

Responsibilities

  • Develop, maintain, and enhance existing gate-level STA flows for Apple silicon designs.
  • Work with design teams to understand and debug issues related to constraints, flow scripts, and timing closure.
  • Facilitate and drive STA methodology changes to improve overall STA flows regarding efficiency and silicon timing correlation.
  • Develop and maintain scripts and methods for timing analysis and power reduction.
  • Develop and support methodologies, tools, and flows used in the verification of timing constraints.
  • Analyze timing paths to identify key issues, including post-silicon timing debug.
  • Work closely with EDA vendors to develop and incorporate new capabilities to solve technical problems.

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.
