Thunderbird is an open source project, which means anyone can contribute ideas, designs, code, and time helping fellow users.
Join UsCome work with the Thunderbird team on the most popular open source desktop email client in the world. We are a distributed team comprised of people spread across the globe working on decentralized communication technology based on open standards.
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 an equal opportunity employer and value diversity. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
How to ApplyThe Thunderbird team is growing, and we are looking to hire a dedicated and hardworking engineer to work with us on our ongoing maintenance work as well as feature development.
We’re committed to moving our code base over to using primarily web technologies, and you’ll be an important part of this effort. Contrary to many learning opportunities elsewhere, you’ll have the opportunity to utilize the most groundbreaking developments in the browser engine.
As an engineer at Thunderbird, you will work with our existing 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 both on the code level and as a concrete result in improvements on the product.
This is a remote, full time position. We expect excellent written communication skills so as to foster strong work coordination over email, video conferencing, Matrix, and Bugzilla.
