CPU Performance Engineer, Platform Architecture

Overview

The CPU Platform Architecture team is responsible for pushing the boundaries of both single‑threaded and multi‑threaded CPU performance, to enhance the user experience of many Apple products. The team is composed of experts with deep experience in microarchitecture, ISA definition, performance modeling, power modeling, and workload analysis. We are seeking a highly motivated, innovative, and confident individual to join the CPU Platform Architecture team to help drive advanced exploration for next‑generation iPhone, iPad, Mac, and server CPU designs.

As a CPU Performance Engineer with a focus on the memory subsystem, you will be part of a team that defines and optimizes CPU and cache micro‑architecture. You will collaborate with experienced CPU and SoC designers in micro‑architecture and RTL to assess the feasibility of ideas through modeling, refine ideas, model correlation, and seed new ideas. The role requires the analysis of single‑threaded and multi‑threaded workloads across existing and new product categories to identify bottlenecks and opportunities for improvement.

You will maintain and enhance the simulation environment to enable data‑driven decisions and continually look for ways to boost the productivity of the entire team.

• Knowledge of memory latency tolerance techniques or other aspects of the CPU memory subsystem (e.g., prefetching, caching policies)
• 10+ years of relevant industry experience
• MS or PhD in Electrical Engineering, Computer Engineering, or Computer Science
• Understanding of common data structures and algorithms
• Familiarity with SIMD, vector, or accelerator architectures
• Familiarity with MP performance
• Comfortable working in an environment of uncertainty and able to navigate through ambiguities
• Experience in a research‑driven environment

• BS degree
• Experience in CPU and SoC architecture and micro‑architecture
• Experience with performance simulation environments
• Object‑oriented programming experience in C/C++
• Experience in a scripting language such as Perl or Python

At Apple, base pay is one part of our total compensation package and is determined within a range. The base pay range for this role is between $184,700 and $277,600, and your base pay will depend on your skills, qualifications, experience, and location.
