Working across hardware and software domains, you will leverage laboratory instrumentation, automation, and data analysis techniques to ensure that silicon meets performance, power, and product objectives.

Roles and Responsibilities

• Define and execute end-to-end power, performance, and characterization plans for CPU and SoC subsystems.
• Develop measurement methodologies and experiments to evaluate silicon behavior across a wide range of workloads and operating conditions.
• Debug performance, marginality, and power miscorrelations with pre-silicon projections in post-silicon.
• Analyze interactions between CPU microarchitecture, memory hierarchy, interconnects, firmware, operating systems, and platform components.
• Process, sanitize, analyze, and interpret large datasets to derive meaningful engineering insights and recommendations.
• Collaborate closely with architecture, design, verification, firmware, and software teams to improve current and future products.
• Drive continuous improvements in validation methodologies, tooling, and technical capabilities.

What Are We Looking For?

• Bachelor's, Master's, or PhD degree in Electrical Engineering, Computer Engineering, Computer Science, or a related discipline.
• 5+ years of experience in post-silicon validation, CPU characterization, power/performance analysis, or related fields.
• Good understanding of modern CPU microarchitectures, including out-of-order execution, speculation, memory hierarchies, caching, and system-level performance behavior.
• Knowledge of ARM architectures and ecosystem technologies is a strong plus.
• Solid understanding of semiconductor fundamentals, including transistor operation, FinFET technologies, leakage mechanisms, dynamic power, voltage-frequency relationships, and process variation.
• Strong programming and scripting skills (Python, C/C++, or similar) with experience developing automation, instrumentation, and data analysis solutions.
• Hands-on experience with laboratory equipment, including oscilloscopes, multimeters, power supplies, DAQs, logic analyzers, and automated measurement systems.
• Strong analytical skills with the ability to assess data quality, identify anomalies, validate results, and perform root-cause analysis.
• Experience collecting, processing, and interpreting large volumes of silicon, telemetry, or measurement data.
• Excellent communication, collaboration, and problem-solving skills.
• Self-motivated and capable of independently driving technical investigations from experiment design through final recommendation.
