Senior Electrical Engineer

Department: Hardware

Location: Shanghai

Do you LOVE music? Know a thing or two about working in a high growth, fast paced environment? SONOS is a cutting edge, wireless music product company and we are growing fast… really fast, globally. We are creating the best sounding, easiest to use, most FUN and versatile audio system in the world and are looking to add the brightest and best engineers to our world-class team. We are looking for passionate and energetic people to drive electrical engineering product improvements to take the future of our products to the next level.


The Sonos Continuing and Sustaining Engineering (CaSE) Team drives all design changes for cost reduction and performance improvement to Sonos products once they are released into mass production. Challenges include: keeping up with ever-expanding manufacturing volumes, finding and testing ideas for product improvements, improving yields and driving down costs, improving product reliability and sustainability, and enhancing manufacturing reproducibility.


As the CaSE team continues to grow, we are adding a senior engineer to focus on particular aspects of our product designs. This position will focus on Continuing projects related to electrical designs in addition to supporting traditional Sustaining responsibilities. This role will include hands-on engineering work, direct interaction with our contract manufacturers as well as project management work.

About You

Like a never-accept-less work ethic. An exceptionally low ego-to-talent ratio (none of the first, tons of the latter). A relentless craving to push past your limits and try new things. The smarts and the humble confidence to take on big challenges, make mistakes fast and early, embrace tough feedback, then recover quickly with fresh, startlingly perfect solutions. A fearless willingness to defend great work. And a tendency to totally geek out on music.
