CPU Performance Engineer - Platform Architecture

Cambridge, Massachusetts, United States


Role Number:200519215
Do you have an uncommon desire to seek out and solve exceedingly difficult challenges rather than the easy ones? Do you believe that truly valuable and meaningful accomplishments are the result of pushing the limits of perseverance?

As a CPU Performance Engineer with a focus on the memory subsystem, you will be part of a team that is defining and optimizing CPU and cache micro-architecture. 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 and SoC 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 and look for ways to boost the productivity of the entire team.
