Senior Staff Product Manager, Browser Control Platform

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:

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.

The opportunity is broad: internal teams (Smart Window, New Products’ automated tools), outside AI tools and their users, and web developers. The three share much of the underlying technology, but each reaches its market in a different way. The mandate is to figure out what to go after, and in what order.

What you’ll do:

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.

Measured on:

Adoption across teams and tools, volume of usage through the platform, and sustained reliability and security.

What you'll bring:

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

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
