The Opportunity

Add-ons (or “browser extensions”) are software programs, most often developed by a third party, that allow you to add features to Firefox to customize your browsing experience. With billions of downloads and millions of users every day, add-ons are a significant part of the Firefox experience.

The Firefox Add-ons team manages the add-ons ecosystem. We drive support for add-ons in Firefox and develop and run addons.mozilla.org. On the operations side, we assist add-on developers in creating outstanding products and make sure they are safe to use.

Mozilla is looking for a software engineering student worker to join the Firefox Add-ons team for a twelve-month term, to support our team in improving the addons.mozilla.org platform for users, developers and add-on reviewers.

What You'll Get To Do

  • Join a distributed team to work on a large codebase.
  • Analyze and fix issues reported by users and add-on developers.
  • Improve the add-ons ecosystem experience for developers.
  • Work with software engineers and security experts to help keep add-ons safe for Firefox users.

What You Bring

Minimum Qualifications

  • You have experience with JavaScript and Python in both concept and reading and writing code.
  • You can break complex problems down into actionable steps without losing the big picture.
  • You have an interest in and ability to work with a distributed team, which requires good asynchronous written communication skills as well as good verbal communication skills.
  • You are motivated and eager to learn a lot.

Bonus Points

  • Browser extension experience

Does this sound like the right twelve-month challenge for you? We'd love to hear from you and make you a part of our team.
