Position: 6-month Contract to Hire.

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

WHAT YOU'LL DO

- 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.

REQUIRED QUALIFICATIONS ( 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

Experience may include( Good to Have)

- Traditional DSP / statistical signal-processing algorithms

- Deep Learning / Neural Network based speech enhancement

- Hybrid DSP + ML solutions

- Audio Post-Processing: Hands-on experience developing or integrating real-time audio playback and post-processing pipelines, including:
