three platforms: Windows, Mac and Linux (and other *nix). It was 
developed under the Mozilla Corporation until 2014 when development was 
handed over to the community. The Mozilla Foundation is now the fiscal 
home of Thunderbird. The Thunderbird Council, who lead the community 
effort, has begun hiring contractors through Mozilla in support of this 
venture and to guarantee that all vital services are provided in a 
reliable fashion.

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
