Responsibilities

Algorithm Optimization & Tuning: Implement, tune, and optimize advanced audio processing algorithms, including Acoustic Echo Cancellation (AEC), multi-microphone beamforming, Sound Source Localization (SSL), noise suppression, dereverberation, and Automatic Gain Control (AGC).
Multi-Channel Audio Architecture: Design and manage low-latency embedded audio pipelines to cleanly handle multi-channel inputs and synchronized outputs (e.g., combining 8-microphone array inputs across separate ADCs via ALSA/Linux layers).
Hardware-Software Co-Design: Collaborate intensely with the Austin onsite hardware team to calibrate software processing parameters based on actual physical transducer responses, coordinate mappings, and structural room acoustics.
Android/Embedded Linux Platforms: Extend and enrich embedded subsystems by developing unique audio capabilities within the Android Media Framework, Linux audio layers, and real-time DSP environments.
Next-Gen Audio AI Integration: Prototype, experiment, and integrate emerging machine learning and audio AI technologies for modern speech enhancement, speaker/talker detection, and dynamic noise classification.
Automated Validation Frameworks: Build robust audio software test infrastructure, automated parsing scripts, and continuous integration pipelines using Python or MATLAB to validate real-time digital signal processing outputs.
Ecosystem Certifications: Drive the software side of automated audio validation suites to pass strict third-party certification requirements (such as Microsoft Teams Rooms V5 and Zoom) under realistic meeting space conditions.
Technical Leadership: Act as a software mentor to junior developers and test engineers, enforcing high code quality, multi-threaded safety standards, and robust system documentation.
Networked Audio & Synchronization: Design, deploy, and maintain broadcast-grade networked audio configurations, implementing native AES67 / RTP streaming pipelines and ensuring strict sub-microsecond clock synchronization utilizing PTPv2 (IEEE 1588-2008) protocols over Local Area Networks (LAN).
Custom Linux Distribution Development: Architect, build, and optimize custom embedded operating system images using the Yocto Project compilation framework. Create custom layers, write bitbake recipes, modify device trees, and configure kernel parameters for deterministic, real-time performance.
