Senior Audio Applied Scientist, Edge Technology

Amazon Amazon · Big Tech · Cambridge, MA · Machine Learning Science

Senior Applied Scientist role focused on audio processing for Echo devices, involving research, development, and commercialization of spatial audio and music processing technologies. Requires expertise in signal processing and C/C++, with preferred experience in ML applications for audio.

What you'd actually do

  1. Be the champion of Echo music processing technology innovation from ideation, proof of concept to productization
  2. Propose new research projects, get buy-in from stakeholders, and lead the team for successful execution
  3. Work closely with an inter-disciplinary product development team including outside partners to bring the prototype algorithm into commercialization
  4. Be a team leader in an open and collaborative environment

Skills

Required

  • 5+ years of industry or academic research experience
  • Experience in embedded development in C/C++, or experience with full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations
  • Experience in written and oral communication, including the ability to communicate with all levels in the organization (technical, business, executive)
  • Proven track record in commercializing innovative audio (music processing especially in spatial audio) algorithms
  • Expert knowledge in music signal processing theory and applications- filter design optimization, limiter/compressor, dynamic range compression, up mixing, binaural rendering etc
  • Proficient with real-time audio programming in C/C++ and Python/Matlab

Nice to have

  • Have peer-reviewed scientific contributions in premier journals and conferences
  • Experience with ML application in music processing - generative model (diffusion or auto-encoder) for source separation, up mixing and 3D audio applications
  • Basic understanding of physical acoustics, room acoustics, and transducer theory
  • Good understanding of a full smart audio system design - microphone array, loudspeaker, ADC, gain stages
  • Familiarity with voice processing - beamforming, echo cancellation, noise reduction etc.
  • Understanding of music production process- stereo and multichannel audio formats, mixing/mastering and reproduction
  • Experience with mentoring junior researchers and graduate interns
