Willem Toet will return to his old role as Sauber's head of aerodynamics, the Swiss team has announced.
Toet held the position from 2006 to 2009, during the period when the squad was BMW-owned, but stepped down after the German manufacturer's departure. He will retake the position next month, replacing Seamus Mullarkey, who has requested a change of role.
"The British engineer favors more technical and less management-oriented assignments and will be in charge of Aerodynamic Research," said a Sauber statement.
Prior to joining BMW Sauber in 2006, Toet worked at Toleman/Benetton, Ferrari and BAR.
