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
