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 techniquesNoise Reduction (NR)Residual Echo Suppression (RES)Voice Activity Detection (VAD)Automatic Gain Control (AGC)Wind noise reductionDirection of Arrival (DoA) estimationSpeech 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 algorithmsDeep Learning / Neural Network-based speech enhancementHybrid DSP + ML solutionsAudio Post-Processing: Hands-on experience developing or integrating real-time audio playback and post-processing pipelines, including:Audio mixing/routingVolume / Gain controlMute/duckingChannel mappingEqualizationAudio filteringSample rate conversion, etc.ALSA / Linux Audio: Strong understanding of Linux audio architecture, particularly ALSAReal-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 featuresAutomotive / 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 MatlabAudio Weaver
