Senior Software Engineer

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.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren't beholden to any shareholders only to our mission. 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.

About This Team And Role

Addons.mozilla.org (AMO) is the foundation of the Firefox add-ons ecosystem. It's a showcase for developers to publish and grow their extensions, and a place of discovery for millions of users who customize Firefox to make it their own. AMO carries the responsibility of building a great, secure, and trustworthy experience for both users and developers.

As a Senior Software Engineer, you'll bring a passion for crafting beautiful, accessible experiences to AMO. You'll work closely with designers and product managers to turn ideas into polished features, modernize the platform and its architecture, and see your work reach millions of people around the world. The Add-ons Engineering team builds and maintains AMO as a critical part of Firefox's customizability. Our responsibilities include :

• Frontend and full stack development : React / TypeScript frontends, Django backend, MySQL datastore.
• Platform reliability : deployments, monitoring, and incident response on Google Cloud.
• Feature development : submission flows, trust and safety signals, and DevHub modernization.
• Open collaboration : We work in the open, with contributions from Mozilla staff and community members.
