- 具备忠实实现已批准设计的经验，以及在设计未考虑到的情况下及时提出问题的判断力
- 能够快速在你未编写的大型成熟代码库中开展工作
- 具备编写用户界面自动化测试的经验
- 强大的异步书面沟通能力，因为团队成员分布在不同时区
- 适应在公开环境中工作，因为Bugzilla和Phabricator是开放的

About the team and role
Mozilla's Web Conferencing team owns the media capture and sharing features that make Firefox work for video calls: screen, window, and tab capture, and the interface users interact with when they share content in Google Meet, Zoom, or Jitsi.
We're bringing a set of screensharing improvements to Firefox. The backend work is complete and the UX has been designed and approved. We're looking for a front-end engineer on a fixed-term contract to implement it and ship it.
What you'll do
- Implement approved UX designs for Firefox's screen, window, and tab sharing experience, and see them through to release
- Build browser UI that holds up in a large, widely used codebase: tested, accessible, and localizable
- Work with UX on the cases a design didn't anticipate, and with QA on validating the result
- Support partner testing against major web conferencing services
- Land your work in mozilla-central through public code review on Phabricator
What you'll bring
- 4+ years building production user interfaces with JavaScript, HTML, and CSS
- Experience implementing an approved design faithfully, plus the judgment to flag it when the design meets a case it didn't anticipate
- Ability to get productive quickly in a large, mature codebase you didn't write
- Experience writing automated tests for user interfaces
- Strong asynchronous written communication, since the team is distributed across timezones
- Comfort working in public, since Bugzilla and Phabricator are open
Bonus qualifications
- Prior contributions to Firefox or another open-source browser
- Familiarity with Firefox front-end architecture: browser/, custom elements, XUL, Fluent localization
- Experience with WebRTC or getDisplayMedia
- Accessibility experience with modal dialogs and list navigation
- Experience with Mozilla's test frameworks (browser-chrome, mochitest)
- Experience using AI tooling effectively in front-end development
- Open source environment experience
