Why Mozilla?

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

The Firefox team is a community of engineers who care deeply about delivering the fastest, friendliest, most usable browser possible. We are responsible for making the things you see in the browser work securely, quickly, and well! The Enterprise team is a cross-disciplinary team in charge of improving and maintaining Firefox support for large Enterprise deployments. As part of the team, you will be responsible for all things related to OS integration - such as updates, installs, and integrating Firefox with the different operating systems - and helping us grow our user base.

Our team is geographically-distributed, and working in the open is the norm. We contribute to the code driving Firefox on a number of desktop platforms - Windows, Linux, and macOS.
