Title: Thunderbird Software Engineer

About Thunderbird

Thunderbird is a email client depended on daily by 25 million people on

three platforms: Windows, Mac and Linux (and other *nix). It was developed by 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 software engineer you will be maintaining and improving the existing Gecko-based Thunderbird but also pave the way for its transition to being based on web technologies.

The Thunderbird team works openly using public bug trackers and repositories, providing you with a premier chance to showcase your work to the world.

About the Contract

The Thunderbird project is looking to hire software engineers to help maintain Thunderbird. You’ll be expected to work with community volunteers, the Thunderbird Council, and other employees to maintain and improve the Thunderbird product.

This is a remote, hourly 6-month contract. Hours will be up to 40 a week. You will be expected to have excellent written communication skills and coordinate your work over email, IRC, and Bugzilla.

As a software engineer for Thunderbird you will

* Fix bugs and regressions and address technical debt.

* In collaboration with Thunderbird’s Engineering Steering Committee,

replace/rewrite modules to prepare Thunderbird for the transition to a

new platform.

* Maintain and improve Thunderbird to ensure that both nightly builds

and releases are always possible.

* Follow improvements made by Mozilla engineers for the Firefox platform

process and implement those for Thunderbird.

* Be a self-starter. In a large code-base it’s inevitable that you

conduct your own research, investigation and debugging, although others

in the project will of course share their knowledge.

* Work with both volunteers and employees across the world to fix issues.

* Collaborate with QA, Security, Localization, and Release Engineering

for coordinated code releases.

Your Previous Experience

Since we are looking to fill one or more positions, we are interested to

hear from junior and senior candidates who can offer the following:

* Solid knowledge and experience developing a large software system (7+

million lines of code).

* Solid knowledge of C++ as well as JavaScript, HTML and CSS.

* Ideally exposure to the Mozilla platform as a voluntary contributor or

add-on author with knowledge of XPCOM, XUL, etc.

* Some experience using distributed version control systems (preferably

Mercurial, Git would be acceptable).

* Some prior exposure to Python and build systems (preferably make)

would be beneficial.

* Experience developing software cross-platform applications is a plus.

* B.S. in Computer Science would be lovely, but real-world experience is

preferred.

Please note that while the Thunderbird project is a group of individuals separate from the Mozilla Foundation that works to further the Thunderbird email client, the Mozilla Foundation is the Project’s fiscal home. The Thunderbird Council, separate from Mozilla, manages the Project and will direct the software engineer’s work.
