The modern web is increasingly developed with a single browser engine in mind, which can result in a degraded, broken, or significantly different experience for Firefox users. Web Compatibility Engineers are key advocates for opening up the web such that users of Firefox browsers can enjoy all that a fast, safe, and global web has to offer.

In this role as a Senior Web Compatibility Engineer you will lead investigations into known and potential compatibility issues, and build new tools to unlock novel approaches for improving compatibility with the existing and future web. You will also serve as an advocate for Firefox browsers, working to resolve issues with top sites and partners.

As a Web Compatibility Engineer at Mozilla, you will:

  • Investigate and diagnose issues reported by Firefox users, identifying bugs in Gecko, bugs in sites, or web platform interoperability deficiencies
  • Identify and connect with website owners and engineers outside of Mozilla. Help them  understand how to repair their code to improve cross browser compatibility
  • Submit patches that fix issues in open source web frameworks
  • Work with Mozilla engineers on fixing Gecko to be more compatible with the web and web standards
  • Build tools to assist in understanding compatibility issues
  • Represent the Mozilla brand through positive communication with site and framework developers, Firefox users, and Mozilla volunteers
  • Become proficient with our code base, multiple languages (JS, Python, C++), and development tools
  • Collaborate with a geographically distributed development team

Your Professional Profile:

  • 4+ years experience developing end-user applications (web-based or native)
  • Deep understanding of web technologies (JS, CSS, DOM, HTML)
  • Strong code debugging skills, including 3rd party code
  • Ability to read technical specifications and navigate large codebases
  • Written and verbal interpersonal skills in English
  • Excited to work in the open as part of the Mozilla open source project, and engage with Mozilla’s global community
