About The Position

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.

Requirements

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.

Nice To Haves

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

Responsibilities

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.
