Job Summary:

Sensory is seeking a polished, proactive and senior level Acoustic (Audio) DSP Engineer with extensive experience in audio processing for varied acoustic environments to work in algorithm development such as AEC, microphone array beam-forming, Noise Reduction, gain control, etc. (...test and benchmark the algorithms in different environments including the sound booth)

Primary Responsibilities:

• DSP design and tuning for acoustic echo cancellation, beam-forming, etc. for active call quality, as well as best-in-class enhancement of speech recognition in noise.
• Support customers with transducer design, selection, placement and turning; and acoustic enclosure co-design.
• Learns and understands existing proprietary voice recognition algorithms in depth.
• Implements voice processing algorithms and related software on hardware platforms.
• Defines and implements simulation scripts for validating, evaluating, and improving the performance of algorithms.
• “Ports” existing technology software to various platforms including DSPs.
• Develops and maintains in-house and customer tools to support the application of Sensory’s voice processing.

Primary Skills/ Speciality / Technical Skills

• Experience with AEC, microphone array beam-forming, Noise reduction algorithms.
• Experience with audio signal processing algorithm implementation.
• Experience with algorithm optimization and code optimization.
• Experience with acoustic measurements and noise control, including using HATS and BT headsets
• Experience designing benchmark tests to evaluate products and algorithms in this area.
• Experience with C, Matlab and some other scripting language.

Education / Key Qualifications / Number of Years in Experience in Field/Career Required or Preferred:

• MS in EE or CS.
• 5+ years of experience in turning and deploying acoustic echo cancellation, beam-forming and noise reduction for mobile, TV, car and conferencing use cases in high volume products.
• Broad and deep experience in signal processing for audio and speech.
• 5+ years of experience programming embedded “C”, demonstrated by a primary programming role in one or more fully-released products.
• Solid knowledge of analytic techniques, statistics, mathematical modeling.
• Ability to develop software from existing code, detailed specification, or general conceptual outline.
• Familiarity with embedded systems hardware, ADCs, DACs, ability to read schematics.
