The chief executive of Fortescue-owned Williams Advanced Engineering has departed the role after less than a year amid the latest upheaval in the company’s fledgling green energy division.

Judith Judson was appointed chief executive of WAE, recently re-branded Fortescue Zero, in 2023. She was tasked by Fortescue executive chairman Andrew Forrest with leading the business as it opened two new facilities in the United Kingdom and talked up increasing headcount by at least fourfold.
