Audio DSP Specialist

Job Title: Audio DSP Specialist Location: Palo Alto, California Work Arrangement: 100% Onsite Position Overview Seeking a highly experienced Audio DSP Engineer to develop, integrate, optimize, debug, and validate real-time audio processing algorithms on automotive infotainment platforms.

The role focuses on voice communication, echo cancellation, microphone array processing, speech enhancement, and automotive audio post-processing.

What You'll Do

• 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 the QA team to perform comprehensive testing, debugging, and validation.

Mandatory Technical Skills

• 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
• Direction of Arrival (DoA) estimation
• Speech enhancement

Expects experience with several voice-processing algorithms, including VAD, AGC, RES, DoA, and wind-noise reduction, rather than requiring every algorithm individually.

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, particularly 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

Skills

• Strong experience with C/C++, Python, and Matlab
• Audio Weaver
