Responsibilities
- Execute and analyze SPEC CPU, SPECrate, SPECjbb, and representative cloud or microservice workloads.
- Characterize CPU, cache, memory, NUMA, and I/O behavior on ARMv9 server platforms.
- Identify performance bottlenecks and debug regressions using PMU counters, profiling tools, system traces, and controlled experiments.
- Track performance KPIs and automate regression detection across software, firmware, and hardware updates.
- Tune Linux kernel parameters, system configurations, benchmark settings, compiler flags, and toolchains, including ARMv9 and SVE/SVE2 code paths.
- Develop automated benchmarking frameworks, scalable testbeds, and data collection, visualization, and reporting pipelines.
- Validate performance for hyperscalers, Kubernetes, enterprise workloads, OEMs, and ODMs, and support customer evaluations and field issues.
- Collaborate with kernel, compiler, silicon, customer, hardware, firmware, and software teams to verify performance improvements.
Requirements
- Bachelor’s degree in engineering, computer science, electrical engineering, information systems, or a related field, or a master’s degree or PhD in a related field.
- At least 3 years of experience in performance engineering, system software, or related work, with minimum-qualification alternatives of 2+ years for a bachelor’s degree, 1+ year for a master’s degree, or a PhD.
- At least 2 years of academic or work experience with programming languages such as C, C++, Java, or Python.
- Strong proficiency in Python and Bash and working knowledge of C/C++ in performance-critical environments.
- Familiarity with ARM-based server platforms, ARMv9 architectures, Linux systems and internals, virtualization, UEFI/BIOS, PCIe/CXL, and NUMA.
- Hands-on experience running and analyzing SPEC CPU, SPECrate, and SPECjbb workloads.
- Experience with perf, VTune, ARM Streamline, TMA, Linux performance tuning, statistical analysis, PMU counters, and system traces.
- Understanding of CPU and system architecture, microarchitectural behavior, memory and platform architecture, workload benchmarking, and performance experimentation.
- Strong analytical, debugging, communication, collaboration, and data-driven problem-solving skills.
About Qualcomm
Qualcomm is a public semiconductor company headquartered in San Diego, founded in 1985, that designs and sells wireless chipsets and platforms for mobile devices, automotive, IoT, and networking, notably the Snapdragon application processors and 5G modems. It also licenses a large portfolio of cellular patents to device makers, generating revenue alongside chip sales; its technology underpins many Android smartphones and emerging automotive and edge-compute systems, and it trades on NASDAQ as QCOM.
