Team
The Executive Support function sits within Strategic Operations and exists to enable Mozilla Foundation’s senior leadership to operate with clarity, focus, and impact.

Working closely with these executives, the EA plays a critical role in enabling effective leadership, supporting organizational priorities, and reducing operational friction across multiple functions. This EA role is based remotely in the UK.
