We make pioneering brands like Firefox, the privacy-minded web browser, and Pocket, a service for keeping up with the best content online. 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.

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.
What is a Senior Staff Software Engineer at Mozilla?
A Senior Staff Software Engineer is the next level from a Staff Software Engineer. At Mozilla this role can vary, but typically a senior staff engineer leads projects requiring implementation with multiple teams, providing technical leadership, building cross-team relationships, and helping the teams deliver on their objectives. They are a guide in their domain and provide observation and evaluation on our strategy and goals affecting numerous teams and turn our strategy into coordinated action for those teams. They mentor others by stewarding responsibilities to more junior engineers, so they can address new ones, while collaborating with leadership on establishing team consensus and providing direction. Typically, a Senior Staff is a technical lead for multiple teams.

What We Do
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.
