Alex Dyer will continue as Kilmarnock manager after agreeing a two-year deal.
Dyer, 54, took caretaker charge in December when Angelo Alessio was dismissed and was then given the job for the rest of the season, leading the club to an eighth-place finish.
He first came to Rugby Park as Steve Clarke’s assistant and continues to work with Clarke as Scotland assistant.
Dyer says his “passion and desire” for Kilmarnock has “strengthened during these months away from football”.
He added: “I’ve always enjoyed a close bond with the fans and I’ve been blown away by how they’ve continued to show their support during the shutdown.
“This season, starting out without supporters in the stadium, will be unlike any other but that continued sense of unity can help carry us through until we’re able to reunite at Rugby Park.”
Main shareholder Billy Bowie said Dyer had provided “stability at a crucial time last season”, adding the board “will support him as much as we possibly can when the transfer window opens”.
Meanwhile, Kilmarnock announced on Sunday that coach Massimo Donati has left the club.
