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 in developing, integrating, debugging, tuning, and validating audio algorithms on an embedded production platform.

• - 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.

• - 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 ()
• - 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
