About Thunderbird

Thunderbird is a email client depended on daily by 25 million people. It was developed under the Mozilla Corporation until 2014 when development was handed over to the community. The Thunderbird Council, who leads the community effort, has begun hiring contractors in support of this venture.

You will join the team that is leading Thunderbird into a bright future. As a build engineer you will be serving the community, empowering them to make their contributions available to over 25 million people.
