In short
We are seeking a SoC Performance Architect to lead server CPU workload analysis, performance modeling, competitive projection, and optimization. This role focuses on end-to-end system performance for complex server workloads, identifying bottlenecks across the compute stack, and driving improvements in CPU, memory, interconnect, I/O, firmware, OS, compiler, and application behavior. The ideal candidate combines deep architectural expertise with analytical rigor and hands-on performance debugging experience.
Responsibilities
- Define performance methodologies, metrics, and KPI frameworks for consistent workload tracking and feature evaluation.
- Conduct hardware/software sensitivity studies.
- Perform bottleneck analysis across CPU cores, cache hierarchy, memory subsystem/controllers, on-chip fabric, and I/O.
- Use profiling and PMU tools to capture hotspots, call stacks, CPI breakdowns, memory behavior, and microarchitectural stall data.
- Build analytical and empirical models for workload behavior, scaling, and feature sensitivity.
- Develop performance projections for internal roadmap products and external competitors.
- Identify and prioritize optimization opportunities; drive cross-functional execution with architecture, design, compiler, OS, firmware, and application teams.
- Communicate findings, tradeoffs, and product implications to technical and executive stakeholders.
Requirements
- PhD in Computer Engineering, Electrical Engineering, Computer Science, or related field.
- Deep understanding of CPU microarchitecture, including pipelines, out-of-order execution, branch prediction, caches, prefetching, SMT, and performance bottlenecks.
- Strong knowledge of SoC architecture, including on-chip interconnect/fabric, memory controllers, DRAM systems, coherency, and I/O subsystems.
- Strong understanding of OS and compiler behavior, including scheduling, memory management, synchronization, code generation, optimization, and runtime effects on performance.
- Hands-on experience with industry-standard performance analysis and profiling tools.
- Experience enabling and debugging complex server workloads in Linux environments.
- Strong scripting and data analysis skills for handling large profiling datasets and developing performance models.
Desired Qualifications
- Experience with pre-silicon performance modeling, simulation, or trace-based analysis.
- Familiarity with PMU-based top-down analysis, CPI decomposition, memory subsystem analysis, and sensitivity modeling.
Benefits
- Competitive annual discretionary bonus program.
- Opportunity for annual RSU grants.
- Highly competitive benefits package designed to support your success at work, at home, and at play.
- Qualcomm is an equal opportunity employer committed to providing an accessible process and workplace.
