## About the Role

This is a hands-on engineering role. The ideal candidate should be comfortable developing, integrating, debugging, tuning, and validating audio algorithms on an embedded production platform., * Audio Digital Signal Processing (DSP): Strong hands-on development experience with speech and microphone-array signal processing algorithms. Experience with several of the following components is expected:

 * Acoustic Echo Cancellation (AEC)
 * Adaptive Beamforming: MVDR or similar techniques
 * Noise Reduction (NR)
 * Residual Echo Suppression (RES)
 * Voice Activity Detection (VAD)
 * Automatic Gain Control (AGC)
 * Wind noise reduction
 * Directional of Arrival (DoA) estimation
 * Speech enhancement
 * Audio Post-Processing: Hands-on experience developing or integrating real-time audio playback and post-processing pipelines, including:
 * Audio mixing / routing
 * Volume / Gain control
 * Mute / ducking
 * Channel mapping
 * Equalization
 * Audio filtering
 * Sample rate conversion, etc.
 * ALSA / Linux Audio: Strong understanding of Linux audio architecture, particularly ALSA
 * Real-time Audio SW Development experience: Strong C/C++ software development experience with real-time audio processing systems., * Commercialization experience: Voice communication and/or Voice recognition features
 * Automotive / IVI Experience - Strong Plus: Experience developing audio systems for automotive or IVI platforms is highly desirable.
 * Hands-on experience with DSP Concepts Audio Weaver (AWE) is highly desirable.
 * Experience with acoustic measurement, tuning, and validation equipment and tools: HATS, HEAD acoustics, Audio Precision
 * Experience with Python and MATLAB also highly desirable

## Description

* Development of audio processing stack: Drive the implementation and optimization of the infotainment audio software stack.
 * Develop and integrate voice communication and voice recognition solutions for IVI (In-vehicle infotainment) platforms.
 * Work closely with HW engineers and the system integration team to ensure tight integration and that the audio stack meets high-quality standards.
 * Work closely with QA team to perform comprehensive testing, debugging, and validation.
