Job description

This role involves working on software that validates Apple's silicon across all devices. The team consists of experienced software engineers focused on functional validation of CPUs, caches, and memory subsystems. The main goal is to identify logic design and circuit bugs before product release. Collaboration with SoC design and product engineering teams is essential to debug and resolve silicon issues.

Requirements

  • BS in Computer Science, Electrical Engineering, Computer Engineering, or related field.
  • A minimum of 3 years relevant industry experience.
  • Experience in post-silicon validation, PVT, system bring-up, or silicon debug.
  • Strong understanding of CPU microarchitecture, cache coherency, and memory hierarchy.
  • Knowledge of SoC-level power, clocking, and voltage domains.
  • Proficiency in C/C++ and scripting (Python) for automation and analysis.

Responsibilities

  • Validate CPU cores, cache coherency, and memory hierarchy behavior on post-silicon platforms.
  • Develop targeted stress tests to expose incorrect behavior under varying operating conditions.
  • Partner with design and architecture teams to correlate silicon behavior with intended micro architectural design.
  • Catch incorrect silicon behavior and issues before product release.
  • Identify sensitivity to PVT shifts, including incorrect behaviors and intermittent failures.
  • Collect and analyze silicon data to understand system behavior across operating conditions.
  • Provide actionable feedback to PVT and other teams to refine operating limits.

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.
