Senior Software Engineer (Localization)

About the Role

Mozilla, a pioneer in shaping the internet for the better, is seeking a Senior Software Engineer to join its Localization Team. This team is crucial in managing the infrastructure that powers localization across all Mozilla products and services, supporting a global community of volunteer localizers. As a Senior Engineer, you will contribute to a range of Mozilla localization projects and technologies, from open-source libraries like moz-l10n to Pontoon, the Django-based Translation Management System. Your work will also encompass internationalization features that shape the experience of Firefox and other Mozilla products, engaging with the development of standards like Unicode MessageFormat and DOM Localization.

The role involves architectural discussions and driving feature development within the team. Senior Engineers at Mozilla are expected to work independently on well-defined projects, collaborate closely with peers, and play a key role in delivering high-quality software that advances the team’s goals and Mozilla’s mission. This is an opportunity to be part of a team that is committed to making the internet better for people, not companies.

Mozilla’s work is diverse, focusing on areas including AI, social media, security, and more, all while maintaining its core mission. As a wholly owned subsidiary of the non-profit Mozilla Foundation, the company is driven by its mission rather than shareholder interests, allowing for a unique environment that combines the benefits of a non-profit ethos with the innovation of a technology company.
