• Mail protocol implementations or re-implementations in JavaScript.
• Crafting tests for operational performance, and addressing performance bottlenecks.
• Integrating some of the best parts of the more popular add-ons into core.

We’re looking for someone with:

• Dedication to open source and open standards.
• A mission of making a concrete positive impact on the day to day communication experience for tens of millions of users.
• Strong understanding of web technologies.
• About five years of validated experience developing with JavaScript/HTML/CSS.
