Role Overview
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.
About this team:
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! Desktop Integrations is part of Firefox Growth: a cross-functional team of engineers, product managers, designers, and data scientists focused on helping more people discover, choose, and keep coming back to Firefox.
We build the places where Firefox meets the operating system: notifications that reach people even when Firefox is closed, pinning web apps to the taskbar, launch on login, and making Firefox the default browser on Windows and macOS. We ship these as experiments, measure their impact on engagement, and double down on what works.
