Thunderbird is a free and open source email, newsfeed, chat, and calendaring client, that’s easy to set up and customize. One of the core principles of Thunderbird is the use and promotion of open standards - this focus is a rejection of our world of closed platforms and services that can’t communicate with each other. We want our users to have freedom and choice in how they communicate.
We are a fully remote and distributed team. You will work with staff and community members from all over the globe. We are key contributors to open source, allowing you to show your skills to the world and learn from a diverse community.
