Senior SoC Performance Architect: Server CPU Modeling

Qualcomm; United States; On-site; USD 198,600 - 297,800; Full time

Job summary

Qualcomm Technologies, Inc. in the United States is seeking a Senior SoC Performance Architect to lead server CPU workload analysis, performance modeling, and optimization across hardware and software.

You will evaluate internal and competitor SoC products, build performance insights, and guide product decisions. The ideal candidate combines deep CPU architecture knowledge with strong analytical skills and hands-on performance debugging in Linux environments.

Qualifications

• PhD or advanced degree with 5+ years of industry experience in CPU performance modeling and analysis.
• Deep understanding of CPU microarchitecture and bottlenecks.
• Strong knowledge of SoC-level architecture and memory/I/O subsystems.
• Experience with Linux-based environments and performance tools.
• Hands-on experience with profiling data and performance models.

Responsibilities

• Drive workload-based performance analysis for server SoCs, with emphasis on CPU-intensive and system-level workloads.
• Enable, run, and characterize complex server workloads on pre-silicon and post-silicon platforms.
• Perform detailed bottleneck analysis across CPU cores, caches, memory hierarchy, on-chip fabric, memory controllers, and I/O subsystems.
• Build analytical and empirical models for workload behavior, performance scaling, and feature sensitivity.
• Develop performance projections for internal products and competitive external products.
• Conduct sensitivity studies to hardware and software parameters such as frequency, cache size, memory latency/bandwidth, prefetch behavior, SMT, compiler options, scheduling, and system configuration.
• Identify optimization opportunities across both hardware and software, and drive recommendations to architecture, design, compiler, OS, firmware, and application teams.
• Partner closely with hardware and software organizations to root-cause performance gaps and drive cross-functional optimization plans.
• Define methodologies, metrics, and KPI frameworks for workload analysis, performance tracking, and feature evaluation.
• Use profiling and performance monitoring tools to collect PMU data, hotspot profiles, call stacks, CPI breakdowns, memory behavior, and microarchitectural stall analysis.
• Summarize findings for technical and executive audiences, including architecture tradeoffs, product implications, and competitive positioning.
