Senior Audio Researcher, Advanced Technology

Location: Boston, London, Santa Barbara

Req#: 6067

The Advanced Technology group works at the intersection of audio signal processing, machine learning, acoustics, and human listening. We define and deliver the core technologies that enable new and unique listening experiences from Sonos products. 
We are a cross disciplinary team of researchers, audio engineers, data scientists, and software engineers, working together to identify and realise how audio technology can be used to change the world we live in for the better, through sound. 
We are looking for a Senior Audio Researcher to join us on this journey
About You

More than a candidate that checks every box, we’re looking for people who are excited to work, learn, and grow at Sonos—no matter their background or how they identify. If that’s you, we hope you’ll apply for this role.

You enjoy a challenge.

Inquisitive and focused, you see every challenge as an opportunity. You’re ambitious and comfortable making mistakes because you learn from them and bounce back quickly. You would rather create the future than wait for it. You prioritize long-term value over short-term objectives.

You love to listen.

You approach every interaction with curiosity and a desire to understand. You want to make a positive impact in the world. You’re passionate about culture and know the power that music, film, podcasts, games, and stories have to bring people together.

What You’ll Do
  • Conduct cutting edge research in audio signal processing and machine learning.
  • Design, develop, and evaluate methods for analysing, processing, and rendering audio and music. 
  • Stay abreast of the latest audio DSP and ML related trends in industry and academia.
  • Identify the emerging opportunities presented by new methods and developments in the field, and communicate them to internal stakeholders and colleagues.
  • Use your domain knowledge to help drive forward our research program into previously unexplored areas.  
  • Apply your scientific knowledge to develop technologies from early concepts to tangible and demonstrable realisation.   
  • Clearly communicate research findings to stakeholders both within and outside of the Advanced Technology group via verbal, written, and practical demonstrations. 
  • Work closely with your colleagues in Research Operations and Engineering to help mature new technologies from “validated in the lab” to “in products”.

  • Ability to clearly communicate, present, and disseminate research findings to both specialist and general audiences. 
  • Comfortable working with teams across multiple geographies and time zones.

  • Musical background (playing, producing, engineering).
  • Experience designing and conducting experiments on audio perception, psychology, cognitive neuroscience. 
  • Proficiency in Python and experience using the core scientific computing and machine learning libraries (e.g. NumPy, SciPy, ScikitLearn, Tensorflow, Keras).
  • Experience in sourcing, cleaning, visualising, and modelling data. 
  • Experience using cloud based computing for analysing and processing large datasets (e.g. AWS, GCP). 
  • Experience in real-time audio processing. 
  • Experience in C/C++ and Matlab.
  • Experience in developing technologies for audio reproduction systems.
