Jimmy Calderwood has become Kilmarnock manager but will initially only take charge until the end of the season.
Killie chairman Michael Johnston said that the former Aberdeen boss "ticked the right boxes" because of his SPL experience.
Calderwood said: "I am just delighted to get back into the game."
He will be joined at Rugby Park by Jimmy Nicholl, who was also his assistant at Pittodrie.
Calderwood explained that he had not enjoyed his first-ever break from football, having left Aberdeen at the end of last season.
Asked why he had taken the job, he said: "Because the chairman asked me.
"It is a famous old club and we have been out of the game for what seems like a long time and was there something going to happen in the next three or four months?"
Calderwood recognised that the short-term nature of the arrangement meant it was open to him to move to another club at the end of the season.
"We will just have to see what happens," he said. "I think it's good for the club that it's only four months and it's good for us."
