Senior Staff Product Manager, Browser Control Platform

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.

This role owns the foundation that lets other software drive Firefox: the secure, reliable connection an outside tool or another team uses to act inside the browser, and the building blocks they call to do it. It enables the teams building on it — internal teams, outside AI tools — to create their own products on top. This role owns the shared layer and the strategy for it. It's a hands-on, technical role in a fast-moving, greenfield space, so it's as much strategy as execution.

• Own the shared foundation and the building blocks it gives other software, and make them reliable and secure.
• Push the open standard (WebDriver BiDi) forward, and build Firefox-only advantages the standard won't cover
• Design the safety controls: let a person approve actions, see when software is acting for them, and take back control.
• Define the strategy for any major third-party AI assistants people already use.
• Serve internal teams (Smart Window, New Products) and outside tools through one shared layer.

• A product-minded engineer, or a very technical PM who can drive a technical product
• Developer-space experience, with the range to think about consumers and internal platforms
• Comfortable setting strategy in ambiguity; own a technical contract other teams depend on
• Strong instincts on security and trust. Nice to have: web standards, MCP, browser automation

• 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)
