Who you are
- 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 the job involves
- 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
- 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
