Why Mozilla?

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

The Localization Team manages the infrastructure that powers localization across all Mozilla products and services, and supports our global community of volunteer localizers. We are looking for a passionate and experienced Technical Program Manager to lead and scale localization efforts across a wide range of products.

In this role, you will partner with UX, Content, and Engineering teams to ensure products are localization-ready from design through release. You will work closely with language service providers (LSPs) and an international community of volunteers, and contribute to shaping the long-term direction of localization at Mozilla.

What you’ll do:

Lead and scale localization initiatives by working closely with volunteer localizers, ensuring sustainability and impact across products.
Drive localized product releases end-to-end, defining testing and quality strategies, setting priorities for localization bugs, and enabling localization communities to deliver high-quality results at scale.
Own localization requests from internal partners, coordinating intake, scoping, and execution with LSPs and external platforms to deliver localized content on time and at quality.
Make and communicate informed trade-offs to optimize time-to-delivery, quality, and resource allocation, using data and experience to guide decisions.
Partner with engineers and other localization program managers to design localization-ready features, improve tooling and workflows, and reduce risks.
Collaborate and influence effectively across regions and time zones, building strong relationships with internal clients and teammates to align on priorities and execution.

What you’ll bring:

Localization knowledge/experience:
- Proven expertise in localization processes, workflows, and common industry formats used for software and web localization.
- Experience working with online translation software, computer assisted translation tools and translation management systems.
- First-hand experience localizing software and/or web content at scale, with an understanding of quality, release, and maintenance considerations.
- Excellent written and verbal English skills.
- Fluency in at least one language other than English, or a deep understanding of linguistic complexity (e.g. grammar, scripts, text directionality) across a variety of languages.
Technical skills:
- Ability to read and navigate source code to identify internationalization and localization issues, and collaborate effectively with engineers to propose and implement solutions.
- Experience with GitHub as a platform for both code (version control) and project management.
- Ability to evaluate tools and design workflows to automate or streamline repetitive localization tasks, using scripting or other technical approaches as appropriate.
Collaboration and leadership:
- Self-motivation, ability to solve problems and make decisions independently in ambiguous environments.
- Proven experience working effectively across teams, regions, and time zones, building trust and alignment with a diverse set of stakeholders.
Commitment to our values:
- Welcoming differences
- Being relationship-minded
- Practicing responsible participation
- Having grit

Bonus points:

Experience working with community-driven or volunteer-based localization models, particularly in open-source or non-profit environments.
Working knowledge of Python and Bash to automate or streamline localization and release workflows.
Experience using issue and project tracking tools (e.g. Bugzilla, Jira, Trello, or similar) to triage, prioritize, and track localization work, and to support planning and cross-team visibility.

What you’ll get:

Generous performance-based bonus plans to all eligible employees - we share in our success as one team
Rich medical, dental, and vision coverage
Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute)
Quarterly all-company wellness days where everyone takes a pause together
Country specific holidays plus a day off for your birthday
