Role summary
We are seeking a highly motivated, innovative, and confident individual to join the CPU Architecture and Performance Team. This role focuses on driving advanced exploration for next-generation iPhone, iPad, and Mac CPU architectures. You will be responsible for conceiving and analyzing novel performance ideas using micro-architecture knowledge and performance bottleneck analysis on relevant workloads. You will collaborate with design and implementation teams to iterate on ideas, assess feasibility through modeling, and refine them for implementability. The role requires analysis of single-threaded and multi-threaded workloads to identify bottlenecks and opportunities for improvement, and to maintain and improve the simulation environment for data-driven decisions.
Description
As a CPU Performance Architect with a focus on CPU micro-architecture, you will be part of a team that is pushing the boundaries of innovation in the areas of branch prediction, code/data prefetchers, novel prediction schemes to improve latency and optimization of CPU pipelines. With others you will seek out areas for improvement while collecting data and measurements that either confirm the idea or rule it out. You will collaborate with experienced CPU designers in micro-architecture and RTL to assess the feasibility of ideas through modeling and refine those ideas to make them implementable. The role requires the analysis of specific single-threaded and multi-threaded workloads across existing and new product categories to identify bottlenecks and opportunities for improvement. We collaborate as a larger CPU architecture and performance team to maintain and improve the simulation environment to enable data driven decisions and look for ways to boost the productivity of the entire team.
Minimum Qualifications
BS degree Experience with CPU architecture and micro-architecture Experience conceiving novel performance ideas using micro-architecture knowledge and performance bottleneck analysis on relevant workloads Experience working with design and implementation teams to iterate on ideas to solve timing and power efficiency challenges and fit them into system constraints Experience in performance and/or power simulation environments, such as taking ideas from concept to C/C++ simulator implementation Experience in scripting languages such as Perl or Python
Preferred Qualifications
20+ years of relevant industry experience MS or PhD in Electrical or Computer Engineering or Computer Science Understanding of common data structures and algorithms Knowledge in software design patterns Familiarity with SIMD and vector architectures Knowledge of OS internals and compiler technologies Comfortable in an environment of uncertainty and able to work through ambiguities Communication, influence and negotiation skills
