Audio DSP Engineer

• 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.

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
