Windows Audio Software Engineer (Voice AI), Senior

Stack

Responsibilities

• ▹Own feature development end-to-end for Voice AI capabilities on Windows, including wake-on-voice, on-device ASR, translation, transcription and TTS
• ▹Gather and refine technical requirements with internal and external partners; translate product goals into engineering requirements, architecture and milestones
• ▹Co-design and implement Windows audio + driver stack solutions leveraging Qualcomm SoC CPU/DSP/NPU capabilities while meeting strict latency and power targets
• ▹Build or extend components across user-mode and kernel-mode boundaries (UMDF/KMDF), integrating with Windows audio frameworks
• ▹Drive low-power audio architecture for "always-on" use cases, including concurrency and power-mode transitions
• ▹Optimize and validate performance using Windows diagnostics and debug complex multi-threaded, multi-processor issues across HW/SW boundaries
• ▹Communicate development status, risks and mitigations to technical leads and stakeholders
• ▹Participate in roadmap planning and execution and contribute to process improvements

Requirements

• ▹Bachelor's degree in Engineering, Information Systems, Computer Science or related field plus 2+ years of software engineering experience (1+ year with a Master's)
• ▹2+ years of academic or work experience with a programming language such as C, C++, Java, Python, etc.

Nice to have

• ▹Master's degree in Engineering, Information Systems, Computer Science or related field
• ▹3+ years of industry experience in software engineering focused on Windows system software, device drivers, multimedia/audio, platform software, or performance/power-sensitive products
• ▹Proficiency in systems programming (C/C++ preferred) and delivering production-quality code in complex codebases
• ▹Strong Windows development skills using Visual Studio, Git-based workflows and disciplined debugging
• ▹Solid understanding of Windows OS fundamentals: processes/threads, synchronization primitives, memory, I/O, performance diagnostics
• ▹Experience developing or integrating Windows drivers using KMDF and/or UMDF
• ▹Hands-on multi-threaded programming, concurrency control and performance/latency tuning experience
• ▹Windows audio ecosystem experience: audio drivers, WASAPI, audio effects/APOs, audio policy
• ▹Experience using AI-assisted development tools (e.g. GitHub Copilot / Microsoft Copilot) to improve productivity across the development lifecycle
• ▹Experience with low-power/always-on audio and power-state transitions (e.g. Modern Standby)
• ▹Experience optimizing workloads across heterogeneous compute (CPU + DSP + NPU) and understanding latency vs. power vs. quality tradeoffs
• ▹Exposure to Voice AI pipelines: ASR/TTS, speech translation, transcription, streaming/buffering strategies
