Petr Cech will return to Chelsea in an advisory role after retiring from his duties as a goalkeeper last month, aged 37.
Cech will perform an intermediary role between the club's new manager and director Marina Granovskaia, which had been left vacant since Michael Emenalo quit as technical director nearly two years ago.
"Petr Cech returns to Chelsea as Technical and Performance Advisor," said Chelsea in a statement.
"The focus of the job will be to provide advice on all football and performance matters throughout the club as well as embed and facilitate strong links between our men's and academy teams, ensuring that the various support departments are working together effectively."
"I'm looking forward to the new challenge and hope I can use all of my football knowledge and experience to help the team achieve even more success in the future."
