Senior iOS Engineer - Mozilla

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.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation, meaning we aren’t beholden to any shareholders — only to our mission. Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.
