Audio DSP Specialist

The AES Group • Palo Alto, CA

3d • Onsite

About The Position

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.

Requirements

• 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.
• 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.
• Strong understanding of Linux audio architecture, particularly ALSA.
• Strong C/C++ software development experience with real-time audio processing systems.

Nice To Haves

• Traditional DSP / statistical signal-processing algorithms
• Deep Learning / Neural Network-based speech enhancement
• Hybrid DSP + ML solutions
• 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

Responsibilities

• 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.
