AUDIO DSP Engineer

ABOUT THE ROLE
We are looking for an experienced Audio DSP Engineer to join our In-Vehicle Infotainment (IVI) audio development team for electric vehicle platforms. The role will focus on real-time audio signal processing, particularly voice communication / ECNR and audio post-processing.
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.
Responsibilities
 Development of audio processing stack: Drive the implementation and optimization of the infortainment 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.
MUST HAVE
Audio 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
Good to Have
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, particulary ALSA
Real-time Audio SW Development experience: Strong C/C++ software development experience with real-time audio processing systems.
