Williams has hired Mercedes engineer James Vowles as its new team principal ahead of the start of the 2023 season.
Vowles most recently spent four years as Motorsport Strategy Director at Mercedes, and was previously in charge of race strategy for Brawn GP.
He replaces Jost Capito, who left Williams after two years at the helm of the team at the end of the 2022 season.
The team have struggled in recent seasons and finished 2022 bottom of the constructors’ championship standings.
Vowles said in a statement the team had “tremendous potential” to climb back to the top of F1.
“The team is an icon of our sport, one I greatly respect, and I am very much looking forward to the challenge. Mercedes have been hugely supportive on my journey, and we part on excellent terms after over 20 years of working in Brackley,” he said.
“I am grateful for everything Toto [Wolff] and the team have provided, and it has been such a special experience to journey together through failure and success. Williams Racing have placed their faith and trust in me, and I will do the same in return.
Williams has tremendous potential, and our journey together starts in a matter of weeks.”
