Develop low\u2011latency code paths using deep knowledge of the Windows loader, PE format, NTDLL, COM, WOW64/ARM64EC, and OS subsystem boundaries. Performance Optimization Design robust API\u2011interception layers using Detours\u2011style hooking and safe injection techniques to remediate compatibility or performance issues. Analyse end\u2011user scenarios, productivity suites, browsers, media applications, and tech\u2011press contents and propose solution to achieve best power and performance metrics. Identify OS, driver, and application bottlenecks; drive optimizations across CPU scheduling, memory behavior, I/O paths, and GPU/Display interactions. Implement/generate quantitative performance improvements using ETW, WPA, WPR, and WinDbg. Debugging \u0026 Diagnostics Debug complex issues spanning user\u2011mode, kernel\u2011mode, WOW64/ARM64EC translation layers, and cross\u2011process interactions. Use ETW\u2011based telemetry, WER, memory dumps, GPU/Display traces, and kernel debugging to identify root causes and drive OS/platform fixes. Security \u0026 Deployment Ensure all system components comply with code integrity (CI) and enterprise security policies. Manage code\u2011signing workflows for drivers and user\u2011mode binaries. Support large\u2011scale deployment and rollback of drivers, and runtime components using enterprise mechanisms. Power Optimization Analyze and tune Windows PPM (Power \u0026 Performance Management), CPU QoS levels, frequency scaling, and thread scheduling behavior on WoS platforms. Collaborate with silicon power-management teams to ensure optimal performance\u2011per\u2011watt in interactive and background workloads. Cross\u2011Team Collaboration Work closely with Microsoft OS teams, OEMs, ISVs, and internal platform groups on performance investigations and app compatibility. Present root\u2011cause analyses, design proposals, and performance wins to senior engineering leadership. Required Qualifications Technical Expertise Expert\u2011level knowledge of Win32, Windows internals, loader/PE, COM, WOW64/ARM64. Hands\u2011on experience developing user\u2011mode and kernel\u2011mode drivers and system services. Proficiency in API hooking/Detours, DLL injection, and safe redirection of system APIs. Strong debugging skills with WinDbg, ETW (WPR/WPA), KD, memory\u2011dump analysis. Demonstrated ability to optimize power, thermals, QoS, and performance on mobile/PC SoCs. Programming Skills Expertise in C/C++, Windows driver frameworks (WDF/KMDF/UMDF), COM, and low\u2011level synchronization. Familiarity with modern C++ patterns for low\u2011overhead runtime components. Soft Skills Excellent problem\u2011solving skills with a strong drive toward root\u2011cause resolution. Ability to collaborate across OS, silicon, OEM, and application teams. Clear communication of technical findings to executives and cross\u2011functional partners. Preferred Qualifications Prior experience with Windows\u2011on\u2011ARM, ARM64EC, and x86/x64 emulation execution models. Experience with performance analysis for tech\u2011press benchmarks and creator workflows. Contributions to OS\u2011level performance or reliability improvements in commercial products. Familiarity with GPU/Display pipelines, input subsystem (pointer/touch), and multimedia stack behavior.\n\nApplicants: Qualcomm is an equal opportunity employer.
