The Mozilla Corporation's Gecko networking team is looking for skilled developers to work on a first-class networking stack and improve web experiences for millions of Firefox users. The team is working on the core of the browser that moves the web. The fundamental network protocols and features like HTTP, QUIC, caching and DNS are our responsibility. We strive to provide a performant and secure browsing experience for the users. Furthermore we work on advanced web platform networking API like Fetch and WebTransport. We improve our existing implementations and together with the broader community we advance the web through the evolution of relevant standards.
Is debugging networking protocols or multi-threaded applications an exciting challenge for you? If you’re also enthusiastic about working collaboratively with a worldwide community, we'd love to hear from you!
Opportunities to collaborate with other browser teams, and working in the open is the norm. Firefox is a mature project always looking for new optimizations, and we are trying to write some of our new components in Rust. You’ll be responsible for writing code, tests, specifications, building prototypes, solving problems, and analyzing data. You'll get feedback from real users and synthesize it into bug reports, feature designs, and strategic direction to make the web platform even better over time.
In this role you will:
Design and implement new web platform features in collaboration with the web community.
Debug and fix problems in our multi-threaded codebase.
Debug platform-specific networking issues.
Improve Firefox’s stability and correctness.
Analyze and reduce Firefox’s memory usage.
Work cooperatively with other Mozillians to identify and correct issues.
