Responsibilities
- Design, develop, optimize, debug, and validate Linux kernel technologies involving CPU scheduling, CPU topology, CPUFreq/DVFS, power management, virtualization, and memory management.
- Analyze cross-layer system problems involving workloads, the Linux kernel, firmware, CPU architecture, cache and memory hierarchy, and hardware.
- Develop scheduler policies, workload placement, frequency management, topology-aware scheduling, and workload-aware performance optimizations.
- Characterize workloads and analyze scheduling behavior, CPU utilization, scalability, latency, cache behavior, power, and performance.
- Evaluate processor and SoC capabilities and contribute to Linux kernel architecture, design, implementation, platform enablement, and commercialization.
- Validate kernel technologies across QEMU, FPGA emulation, and production silicon using ftrace, tracepoints, perf, trace-cmd, crash analysis, and JTAG.
- Contribute to upstream Linux and open-source system software, architecture and code reviews, technical documentation, mentoring, and technical guidance.
- Collaborate with hardware, firmware, performance, virtualization, internal engineering, customer, partner, and open-source teams.
Requirements
- Bachelor’s degree in Engineering, Information Systems, Computer Science, or a related field plus 6+ years of software engineering or related experience; alternatively, a master’s degree plus 5+ years or a PhD plus 4+ years.
- 3+ years of experience with a programming language such as C, C++, Java, or Python.
- Deep expertise in C programming and Linux kernel development, including hands-on experience with Linux kernel subsystems such as CPU scheduling, CPU topology, CPUFreq/DVFS, power management, interrupts, timers, governors, platform enablement, or device drivers.
- Strong understanding of computer architecture, including CPU microarchitecture, cache hierarchy and coherency, memory ordering and hierarchy, NUMA/topology concepts, and interrupt architecture.
- Significant experience analyzing and optimizing system performance and power and correlating workload behavior with kernel, firmware, and hardware behavior.
- Demonstrated ability to independently debug difficult system-level problems involving hardware, firmware, operating-system software, and applications.
- Extensive experience with Linux debugging and performance-analysis tools including perf, ftrace, trace-cmd, kernel tracepoints, crash dumps, and JTAG-based debugging.
- Experience with Git, code-review workflows, large-scale production software, and preferably QEMU, FPGA, emulation, or pre-silicon development environments.
- Preferred qualifications include a master’s degree with 8+ years of relevant systems software experience or equivalent practical experience, ARM and RISC-V expertise, platform bring-up, device tree/ACPI, interrupt controllers, timers, memory controllers, and upstream Linux contributions.
- Ability to work on technically ambiguous problems, evaluate trade-offs, develop robust solutions with limited direction, communicate complex technical topics, and mentor engineers.

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.
