Former champions Williams have been without a chief technical officer since the departure of Paddy Lowe in 2019, and also need a technical director following the exit last year of Francois-Xavier Demaison.

"The CTO we are bringing onboard has tremendous experience in that domain and will act as a TD (technical director) for the period of time required to build up a new TD or bring one in from the outside," Vowles told at the Austrian Grand Prix.

"You’ll see the individual and think, ‘ah yeah, I get what you mean now’. It’s a positive state whereby I’m confident we have the technical structure in place to move us forward over the next two to four years.

"We still have other areas of the business I’m bolstering, including aero, but irrespective for now that was the major hurdle I wanted to clear out."

Williams are ninth of 10 teams in the constructors' standings.

Vowles arrived from Mercedes as principal in February.
