DevOps 

Location: Remote position based in Mexico

English level: Advanced

As an engineer working on Sonos’ embedded software build system, you will work in a fast moving environment to evolve and improve this system that is central to how Sonos creates its products. The build system is used by hundreds of engineers on a daily basis and its ease of use, health, and performance have a huge impact on productivity and the ability to meet our product vision and goals. We view the build system as not just a set of tools but as much a part of the products as any feature or function. It's an area in which innovation and planning for the future matter as much as for any product feature roadmap. In the process, you will find yourself working with some of the brightest minds in the business across multiple disciplines of software, hardware, and release engineering.

What You’ll Do

● Design, build, analyze, enhance, and refactor elements of the build system used to develop Sonos products

● Support the regular third-party library upgrade cycle tied to Yocto LTS releases

● Patch third-party libraries as needed as part of Yocto maintenance releases
