Jakirovic now moves to Humberside after guiding Kayserispor to a 13th-placed finish, having arrived when the club was in the relegation zone.
He is the fifth managerial appointment under the watch of chairman Acun Ilicali, who took over in January 2022.
“After a thorough and extensive recruitment process, we are delighted to secure the services of Sergej,” Turkish businessman Ilicali told the club’s website, external.
“We believe in the football that he will bring to the MKM Stadium for us and importantly, he has proven himself to be a winner throughout his career.
“My dream for our club has never changed from the first day I took over, and I believe in Sergej as we look forward to the 2025-26 Championship campaign together as one family.”
Jakirovic will bring coaches Marko Salatovic, Marin Ivancic and Andjelo Roguljic with him to Humberside to work alongside Andy Dawson and Erbil Bozkurt in the Tigers’ backroom staff.
