Sonos is a sound experience company. We connect millions of listeners all around the world to the content they want, where and how they want it. Since inventing multiroom wireless audio in 2005, we have continuously innovated the listening experience, designing hardware and software that celebrates sound, empowers our customers, and brings the home to life. Our team is made up of passionate players united by a culture of respect, transparency, collaboration, and ownership who want to inspire the world to listen better.
Having been distributed from the start, we’ve long since been accustomed to having close teammates in entirely different locations and time zones. We ground ourselves in these four principles while working as distributed teams:
Role Location: Some roles require an office while others may be done remotely. Leaders make this decision based on business rationale, role requirements and team needs.
Travel: Some work is better done in person. Teams should meet together in person at critical moments to move work forward.
Meeting Norms: We use our time to drive OKRs and run the business. We normalize asynchronous collaboration and focused work. We give feedback and help each other improve when norms are not followed.
Flexibility: Flexibility done well fuels impact, not hinders it. Teams flex to support one another and employees flex to deliver for the team or business. We flex both ways to drive impact.
