Skinner had been a staple at Red Bull since 2006, beginning as a computational fluid dynamics engineer, then head of aerodynamics, and more recently as chief designer.
Reports indicated Skinner’s departure was of his own volition.
“After 20 years with the team, Craig Skinner, our Chief Designer, will be leaving the Red Bull Technology team,” Red Bull said in a statement.
“Craig has been an integral part of our team and its success, and we would like to thank him for his hard work and commitment.
“The whole Red Bull team wishes him all the best for the future.”
Skinner’s departure is the latest in a long list of high-profile changes to Red Bull.
