Dirk de Beer has stepped down from his role as the Williams’ head of aerodynamics with immediate effect.
Williams have suffered a wretched start to this season’s championship, scoring just four points in six races.
The team’s lack of pace was labelled “embarrassing” by test driver Robert Kubica while Lance Stroll said the team is “not racing out there at the moment, we are surviving.”
The team’s troubles have led to the departure of De Beer, who follows chief designer Ed Wood out of the door.
“Williams can confirm that Dirk de Beer has stepped down from his role as head of aerodynamics, effective immediately,” a Williams spokesperson told Autosport.
“The team would like to thank Dirk for his hard work over the past year and wish him the best for the future.
“Chief engineer, Doug McKiernan, who joined Williams earlier this year will now assume full responsibility over the aerodynamic and design direction of the car, with Dave Wheater [previously head of aerodynamic performance] stepping up to take on the role as head of aerodynamics.”
