The Opportunity

The Contextual Services engineering team is passionate about helping Firefox users find their way on the Web by solving complex, unique, and fun Information Storage and Aggregation puzzles. We help our users get to the right information, in the right context at the right time with less effort, and we are the team responsible for making the things you see in the browser work securely, quickly, and reliably.

We’re a part of the Mozilla Firefox team; our community of engineers is geographically-distributed, and working in the open is the norm. We contribute to the code driving Firefox browser services in a number of languages, including Rust, Python, and Node.js. Our focus is on implementing and fixing things in Firefox as well as helping other teams make it excellent for our users.
