How to Apply for Senior Localization Technical Program Manager

at Mozilla

🏢 About Mozilla

Mozilla is a mission-driven, non-profit-backed technology company that prioritizes user privacy and an open internet over shareholder profits. Best known for Firefox, it also pioneers in AI, social media, and security, all while remaining true to its core mission. Working here means contributing to products used by over 225 million people monthly, with a strong emphasis on open-source collaboration and community.

About This Role

As Senior Localization Technical Program Manager, you will lead the strategy and execution of localization across Mozilla’s suite of products, ensuring they are ready for global audiences from design to release. You’ll partner with UX, Content, and Engineering teams to build scalable localization pipelines, manage vendor and community relationships, and drive continuous improvement. This role is impactful because it directly enables Mozilla’s mission to make the internet accessible and relevant to people worldwide.

💡 A Day in the Life

A typical day might start with a stand-up with engineering to review localization readiness for an upcoming release, followed by a meeting with the vendor team to discuss quality metrics. You’d then analyze community contribution data, resolve a blocker in the localization pipeline, and end the day by drafting a localization strategy deck for a new product initiative.
