How to Apply for Staff Program Manager, Trust & Safety

at Mozilla

🏢 About Mozilla

Mozilla is the maker of Firefox and a champion of an open, accessible internet. Working here means contributing to products and policies that prioritize user privacy, security, and trust over profit—a rare mission in the tech industry.

About This Role

This role is central to protecting Mozilla's users from harm across products like Firefox, Pocket, and VPN. You'll lead cross-functional programs to anticipate safety risks, implement content moderation strategies, and ensure AI systems are fair and transparent, directly shaping the user experience for millions.

💡 A Day in the Life

Start the day reviewing dashboards for safety metrics (e.g., report volumes, false positive rates), then join a stand-up with engineering to discuss a new moderation tool. Afternoon might involve a cross-functional workshop to assess risks of an upcoming product launch, followed by drafting a quarterly program review for leadership.

3

Tailor your resume to emphasize program management: include examples of leading cross-functional programs from scoping to measurement.

4

In your cover letter, connect your personal values to Mozilla's mission—express genuine passion for user safety and an open internet.

5

Research Mozilla's recent Trust & Safety challenges (e.g., Firefox's privacy features, Pocket content moderation) and mention them in your application.

✉️ What to Emphasize in Your Cover Letter

['Your specific experience with content moderation ecosystems and policy implementation standards.', "How you've used data to improve safety outcomes—mention a dashboard or metric you created.", "Your understanding of AI risks and how you've addressed fairness or transparency in a previous role.", "Why Mozilla's mission resonates with you personally, with a concrete example (e.g., using Firefox for its privacy features)."]

  • → Understand Mozilla's product portfolio beyond Firefox: Pocket, VPN, Relay, and how safety applies to each.
  • → Look into Mozilla's corporate structure as a non-profit and how that influences their approach to user safety versus monetization.

⚠️ Common Mistakes to Avoid

  • Focusing only on policy enforcement without showing program management or cross-functional leadership skills.
