Software Development Engineer – Mobile App Platform (Seattle)

Department: Software

Location: Seattle

Req#: 3008

At Sonos, we are passionate about creating and delivering the finest HiFi audio experiences to our customers. Our products stream all the music on earth, in every room, wirelessly, and you control it all from the palm of your hand. It’s easy to use, but keeping things simple and bug free is hard work.


We work closely with user experience experts to develop UX-centric applications that connect people to music. Software Engineers working on mobile applications and web services collaborate with some of the brightest minds across multiple disciplines in software, hardware, and design. Our team learns from our users as we constantly improve their experience – making it easier to find and listen to their music out loud in their home. We have fun and innovate every day in our fast paced and creative environment.


As a Senior Software Engineer in the Music Experience group you will be responsible for both sides of the contract between our global web services and mobile apps. Your team is designing and delivering the technical foundation for user personalization, communication, and education. If you love music, solving challenging software problems, and doing things the right way every time, we’d like to talk to you.

About You

Our band is large. And while there’s plenty of room for all kinds of personalities and skill sets to succeed, there are certain qualities that will help you thrive here.

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.

If this sounds like you, read on and let’s connect soon.
