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:
• 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.

PREFERRED QUALIFICATIONS

• 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
