About the Job

Requirements

  • A Bachelor's, Master's, or Ph.D. in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
  • 10+ years of industry experience in performance engineering, computer architecture, system architecture, or a related field.
  • Strong understanding of processor microarchitecture, computer system architecture, memory hierarchies and cache architectures, interconnects and SoC design, and performance analysis and optimization techniques.
  • Experience with performance modeling, simulation, or architectural analysis tools.
  • Proficiency in C/C++ and scripting languages such as Python.
  • Experience developing, debugging, or optimizing Linux or Windows device drivers.
  • Strong understanding of operating system internals and hardware-software interactions.
  • Experience using profiling and performance analysis tools.
  • 2+ years of experience with high-performance microprocessor design.

Responsibilities

  • Analyze and optimize performance of complex SoCs, processors, and heterogeneous computing systems.
  • Develop performance models, benchmarks, and simulation environments to evaluate architectural tradeoffs.
  • Investigate system-level bottlenecks across CPUs, DSPs, NPUs, memory subsystems, interconnects, and I/O fabrics.
  • Collaborate with hardware and software teams to define performance requirements and drive performance closure.
  • Analyze workload behavior and identify opportunities for improvements in performance, power efficiency, and scalability.
  • Work with operating systems, firmware, and device drivers to understand hardware-software interactions and performance impacts.
  • Develop profiling, tracing, and instrumentation methodologies to characterize system behavior.
  • Interpret silicon measurements and correlate results with simulation and modeling data.
  • Present findings and recommendations to engineering leadership and cross-functional teams.
  • Contribute to architecture reviews and influence future processor and system designs.

Desired Qualifications

  • Experience with DSP, AI/ML accelerators, GPU, or NPU architectures.
  • Familiarity with virtualization technologies, IOMMU, PCIe, SR-IOV, or SIOV.
  • Knowledge of power-performance tradeoff analysis and performance-per-watt optimization.
  • Experience with silicon bring-up and post-silicon performance characterization.
  • Understanding of cache coherence protocols and memory consistency models.
  • Experience with large-scale performance benchmarking and workload characterization.

About the Company

Qualcomm

Designs mobile chips and licenses wireless patents

Qualcomm designs the Snapdragon processors and modems inside many Android phones, and it licenses its wireless patents to device makers around the world. It helped commercialize CDMA, the cellular technology behind 3G networks, and its patents cover core parts of the 4G and 5G standards that phones use to connect. The company does not run its own chip factories; contract foundries make its chips, which it sells to makers of phones, PCs, cars, and connected devices. Device makers also pay Qualcomm royalties for using its patented technology, which forms a second business alongside chip sales. Qualcomm was founded in 1985 and is based in San Diego, California.
