Role summary
Seeking a highly motivated and innovative CPU Performance Engineer to join the CPU Architecture and Performance Team. This role focuses on advanced exploration for next-generation CPU architectures for iPhone, iPad, and Mac. You will analyze CPU micro-architecture, including branch prediction, prefetchers, and pipelines, by collecting data, performing modeling, and collaborating with CPU designers. Responsibilities include analyzing single-threaded and multi-threaded workloads to identify performance bottlenecks and improve simulation environments. Requires experience with CPU architecture, performance/power simulation, and coding in C/C++ and scripting languages like Perl or Python.
Description
As a CPU Performance Engineer with a focus on CPU micro-architecture, you will be part of a team that is pushing the boundaries of innovation in the area of branch prediction, code/data prefetchers, novel prediction schemes and 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, refine ideas and model correlation, and seed new ideas. 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 in performance and/or power simulation environments Coding experience including object-oriented programming with C and C++ Experience in scripting languages such as Perl or Python
Preferred Qualifications
3+ 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 walk through ambiguities Communication, influence and negotiation skills
