Senior Windows Audio Engineer

Quick Facts

• Role: Senior Windows Audio Engineer

• Focus: Windows audio processing for voice reconstruction AI

• Work: Hybrid role based in Wrocław; build and integrate APOs and virtual audio drivers

Description

Design and implement Audio Processing Objects (APOs) for voice reconstruction in the Windows audio capture path, and build virtual microphone/device drivers to expose reconstructed voice as a system-wide input. Integrate with OEM and IHV audio stacks, manage driver and APO releases (including HLK testing and WHQL signing), and optimize latency and performance across PC NPUs, GPUs, and CPUs. Ensure secure model weight handling and inference using Windows security features while collaborating cross-functionally on OEM programs.

• Design and implement APOs for voice reconstruction in the Windows audio capture path

• Develop and maintain virtual microphone and audio device drivers

• Integrate with OEM/IHV audio stacks and ensure compatibility

• Manage release pipeline for drivers and APOs (HLK, WHQL signing)

• Optimize audio processing models for efficient execution on NPUs/GPUs/CPUs

• Ensure security of model weights and inference via Windows security features

• Profile and optimize the audio path for latency and performance

• Collaborate with cross-functional teams on technical foundations for OEM programs

Requirements

• Minimum 5 years of experience in Windows Driver Development and audio engineering

• Deep expertise in Windows internals and C++ programming

• Hands-on experience with Windows Audio Architecture (WASAPI, APO)

• Proficiency developing audio drivers using PortCls, AVStream, ACX

• Strong understanding of audio DSP techniques (AEC, noise suppression)

• Experience with ONNX Runtime, DirectML, Qualcomm QNN, Intel OpenVINO, or AMD Ryzen AI

• Familiarity with Windows security features (TPM, VBS, code integrity)

• Advanced level of English

Nice-to-haves

• Experience with kernel streaming and virtual audio devices

• Knowledge of HLK, WHQL, and INF packaging
