Junior Embedded Software Development Engineer

At Sonos we want to create the ultimate listening experience for our customers and know that it starts by listening to each other. As part of the Sonos team, you’ll collaborate with people of all styles, skill sets, and backgrounds to realize our vision while fostering a community where everyone feels included and empowered to do the best work of their lives.

As a Junior Embedded Software Development Engineer, you’ll contribute to the software that runs on Sonos players to help deliver reliable playback and great experiences across our ecosystem. You’ll work closely with a supportive team of engineers who will help you learn Sonos systems, embedded development practices, and how we ship high‑quality software. You’ll be exposed to foundational areas of the Sonos system such as music playback, device‑to‑device interaction, and partner services.

You’ll grow your skills through hands‑on development, debugging, and collaboration across disciplines like hardware, product management, and user experience. If you love music, enjoy learning, and want to solve challenging problems, we’d love to talk.

This role is for a position on the Partner Integration team. You’ll be working closely with our Music Service Partners (MSPs) to support over 120 integrations on Sonos. Familiarity with API design, SDK integration, and full‑stack software development will serve you well in this role. You will be adding new exciting features, improving existing integrations, and helping shape the future of partner integrations on Sonos.

This is a hybrid position, allowing for a combination of remote work and in‑office collaboration. Qualified applicants must live within commuting distance of our Boston office location and should expect to be in office a minimum of 3 days per week.
