CPU Processor Performance Verification Engineer

Overview

At IBM, work is more than a job - it's a calling : To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better, but to attempt things you've never thought possible. Are you ready to lead in this new era of technology and solve some of the world's most challenging problems? If so, lets talk.

Your Role And Responsibilities

You will be responsible for performance validation, correlation, characterization, and tuning of IBM Z processors, with a focus on both core-level and system-level performance . This role involves pre-silicon and post-silicon performance analysis , developing targeted workloads and benchmarks, and collaborating across hardware and software teams to optimize performance across the stack.

Key Responsibilities

• Collaborate with micro-architects and RTL designers to validate performance features and ensure alignment with architectural models.
• Analyze and correlate performance across pre-silicon models, RTL simulations, and post-silicon measurements.
• Develop and execute performance test plans targeting IBM Z core and system-level features.
• Design and implement assembly and C / C++ tests to stress and validate performance-critical paths.
• Build checkers and monitors to verify performance features and detect anomalies.
• Conduct coverage analysis to ensure comprehensive validation of performance features.
• Debug and tune performance issues on silicon, including pipeline bottlenecks, cache behavior, and instruction throughput.
• Present performance findings and recommendations to cross-functional teams, including architecture, design, and software.
