Job summary

Mozilla is seeking a product‑minded engineer to own the shared foundation and building blocks used by Firefox, internal teams, and external AI tools. You will shape strategy, drive security, and enable cross‑team collaboration in a fast-moving, greenfield space.

The role involves pushing WebDriver BiDi forward, setting safety controls, and coordinating with internal teams like Smart Window and New Products to deliver a unified platform across partners.

Qualifications

• 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.

Responsibilities

• 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.
