Why Mozilla?

Mozilla Corporation is a 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. With over 225 million people using our products monthly, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work spans diverse areas including AI, social media, and security, all while staying true to 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 are not beholden to shareholders, only to our mission. Alongside thousands of volunteer contributors globally, Mozillians design, build, and distribute open-source software that empowers people to enjoy the internet on their terms.

The Opportunity

At Mozilla, we are building the future of the web—a future that is fast, private, inclusive, and people-first. As mobile becomes the primary way billions access the internet, our mission to deliver a secure, transparent, and user-centric browser is more critical than ever.

We are seeking a Staff Android Engineer to help evolve Firefox for Android, an open-source browser with over 100 million downloads on the Google Play Store.
