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, and Pocket, a service for keeping up with the best content online. 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:

We’re looking for a hands-on Mobile Product Manager with a primary focus on Firefox for iOS, while also contributing across mobile (including Android).

This role is about building a better browser, turning downloads into loyal users, and creating experiences that truly stand out. If you’ve shipped mobile apps, obsess over details that improve everyday use, and love turning user insights into real improvements, this is a great opportunity to drive impact at Firefox.

What you’ll do:

• Build a fundamentally better browser experience: fix bugs, refine UI and navigation, improve downloads, menus, performance, and all the small details that make Firefox noticeably better for users who care about privacy, quality and reliability.
• Drive strong activation and retention: focus on the new-user journey, quickly hooking people after they install the app, understanding where they drop off, and relentlessly optimizing the funnel through data, testing and iteration.
• Deliver differentiating features and experiences that make Firefox stickier for key user groups, the kinds of things others can’t or won’t build.
• Work closely with engineers, designers, data science and TPMs to ship high-impact improvements while balancing user needs, technical constraints, privacy and performance goals.
• Stay deeply connected to real users: track App Store trends and discussions, test apps hands-on, analyze reviews and analytics, and turn those insights into concrete enhancements for Firefox on iOS and Android.
• Monitor app health in App Store Connect and Google Play Console (crashes, ANRs, ratings) and support acquisition/retention efforts through ASO, store listings and growth experiments.
• Adapt and optimize Firefox for global markets (Europe, Japan, Asia etc.), keeping cultural differences and local realities like data constraints in mind.

What you'll bring:

• Proven Shipping Experience: Hands-on experience launching or managing apps on the iOS App Store and/or Google Play Store, with clear impact on user experience and metrics.
• Execution Focus: A strong track record of delivering features and improvements under deadlines through effective collaboration with engineering, design and cross-functional partners.
• Mobile & Browser Fluency: Deep understanding of iOS (and ideally Android) ecosystems, app store policies and web browser technologies, with genuine passion for what makes a great browsing experience.
• Data-Driven Iteration: Comfort using analytics, funnels, A/B testing and user feedback to improve activation, retention and overall product quality.
• User Obsession: Natural habit of studying apps, following trends on platforms like X/Twitter and Reddit, and testing experiences yourself to uncover opportunities.
• Global & Growth Mindset: Interest or experience growing products in international markets with sensitivity to local user needs.
• Bonus:
• Experience with mobile browsers or privacy-focused products.
• History of meaningfully scaling an app’s user base.
• Currently maintaining your own side project or app on the App Store or Google Play.

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
• One-time home office stipend
• Annual professional development budget
• Quarterly well-being stipend
• Considerable paid parental leave
• Employee referral bonus program
• Other benefits (life/AD&D, disability, EAP, etc. - varies by country)
