Performance Modeling Software Engineer, Platform Architecture

Apple•Cupertino, CA

About The Position

Join Apple’s Hardware Technologies organization as a member of the system-on-chip (SoC) performance team, helping shape the architecture of future devices. The team collaborates across SoC architecture, design, power, and software to develop world-class caches and memory systems that enable chip components—including CPUs, GPUs, machine learning, camera, display, and connectivity—to work seamlessly together. You will develop and maintain performance models and infrastructure, translating design-space studies and hardware execution models into well-written, high-performance C++ software. The role spans the full performance-modeling lifecycle, from early architectural exploration through post-silicon correlation. You will help architects iterate quickly by ensuring simulators are performant, maintainable, and flexible, while supporting data analysis, visualization, regression testing, simulation runs, and clear presentation of results. You will also develop APIs for non-expert C++ developers, encourage idiomatic coding practices, and help structure codebases for effective AI-assisted development.

Requirements

Bachelor’s degree.
Experience with hardware architecture and design issues.
Experience coding in C++ and Python.

Experience with data structures and algorithms.
Experience with multi-paradigm software development in C++.
Experience with multi-language programming environments and selecting the appropriate tool or language for a task.
Experience with Compiler Explorer and understanding compiler transformations applied to code.
Experience developing code conventions, structure, and documentation that make a codebase tractable for AI-assisted reasoning and navigation.
Experience with architectural and microarchitectural performance modeling.

Nice To Haves

Master’s or Ph.D. in computer science, electrical engineering, or a related field.
