The CPU Platform Architecture team is focused on enhancing CPU performance for Apple products by exploring advanced designs for next-generation devices. As a CPU Performance Engineer, you will concentrate on optimizing the memory subsystem and identifying performance bottlenecks. You will work collaboratively with experienced designers to assess and refine ideas through modeling. The role involves analyzing workloads to improve CPU and cache micro-architecture and contributing to a data-driven simulation environment.

• BS degree in Electrical or Computer Engineering or Computer Science
• 3+ years of relevant industry experience
• 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
• Knowledge of memory latency tolerance techniques or other aspects of CPU memory subsystem
• Understanding of common data structures and algorithms
• Familiarity with SIMD, vector, or accelerator architectures
• Familiarity with MP performance
• MS or PhD in Electrical or Computer Engineering or Computer Science is preferred
• Comfortable in an environment of uncertainty and able to navigate through ambiguities
• Experience in a research-driven environment

• Define and optimize CPU and cache micro-architecture.
• Identify performance bottlenecks and evaluate ideas for improvement.
• Engage with CPU and SoC designers to assess the feasibility of ideas through modeling.
• Refine ideas and model correlation to seed new concepts.
• Analyze single-threaded and multi-threaded workloads across product categories.
• Collaborate with the CPU architecture and performance team to maintain and improve the simulation environment.

• 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.
