About the Company

A lot of companies say they're "mission-driven." Our unique corporate structure guarantees that every decision we make upholds our mission: to ensure the internet remains open and accessible. Beholden to neither shareholders nor investors, Mozilla Corporation is wholly owned by the not-for-profit Mozilla Foundation.

Along with our communities of 20,000+ contributors and collaborators, Mozilla Corporation's staff designs, builds, and distributes software that allows people to enjoy the internet on their own terms. Our flagship product -- the Firefox browser -- has expanded into a family of products that protects users and alerts them of risks, safeguards passwords and provides a secure VPN (with more to come).

By maintaining a safe, open internet we're helping humanity, while also helping the individual humans employed here to reach their personal and professional goals. With a relatively small team serving hundreds of millions of people, a culture of exploration, and a commitment to mentorship, opportunities abound to learn and grow at Mozilla.
