In this highly visible role, you will be at the center of a chip design effort collaborating with all subject areas, with a critical impact on getting functional products to millions of customers quickly.
You will be responsible for silicon performance verification, correlation, characterization and tuning for CPUs. The role involves pre-silicon performance verification as well as developing tests to characterize CPU performance, analyzing and profiling software/applications, correlating and comparing performance across silicon/system software version, and working with OS and compiler teams on performance debug and tuning.

Key Qualifications
Minimum BS and 3+ years of relevant industry experience.
The ideal candidate should have performance modeling, processor verification, or RTL design experience
In-depth knowledge of digital logic design, CPU architecture and microarchitecture
Experience in performance modeling for advanced CPU designs
Experience in developing performance test plans and writing/debugging assembly tests for performance correlation and verification
Good programming skills in assembly, C/C++, Verilog, System Verilog, and scripting
Proven experience in benchmarks and workload analysis
Experience in CPU performance profiling
Good knowledge in compiler techniques and OS for performance optimization
Proven knowledge with developing instruction profiling tools on silicon
Ability to work across teams to optimize silicon performance
Experience in silicon validation is a plus
Should be a great teammate with excellent communication and presentation skills and able to work independently on the owned unit

Description
As a Chip Performance Engineer owning the verification of a certain area of performance features in a chip design, you will have responsibilities as follows:
•\tWork closely with architects and RTL designers on verifying the performance features of the design and correlating with performance models (both pre-silicon and post-silicon)
•\tWork closely with software and application developers on identifying performance bottlenecks and tuning the software
•\tDevelop test plans and test infrastructure/tools for performance tuning, correlation, and verification
•\tImprove and maintain the architectural performance models
•\tDevelop tests in assembly, C/C++, or vectors to debug and correlate the RTL and performance model
•\tDevelop C or Verilog-based checkers for verifying the performance features
•\tDevelop coverage monitors and analyze coverage to ensure all performance features are covered
•\tDebug performance issues and conduct performance tuning on silicon
•\tBenchmark, correlate and compare CPU performance across silicon/OS/compiler versions
•\tPresent CPU performance results to multi-functional teams
•\tWork closely with OS and compiler teams on system and application performance tuning

Education & Experience
Minimum BS and 3+ years of relevant industry experience
