Paul Mitchell has been handed the role of director of player recruitment/development in Chesterfield's new-look backroom team being assembled by manager Dean Saunders.
Mitchell, who has spent five years with the club, previously acted as chief scout under Saunders' predecessors, Paul Cook and John Sheridan. He was instrumental in the recruitment of players such as Liam Cooper, Sam Clucas, Jimmy Ryan and Charlie Raglan.
Following Cook's recent switch to Portsmouth, Mitchell turned down an offer to move to Fratton Park as technical director.
Explaining his decision to reject Pompey's overtures, Mitchell said: "I was flattered to receive the offer but I'm very happy at Chesterfield, working with some good people.
"I also received offers to join John Sheridan and Tommy Wright at their respective clubs when they moved on.
"Dave Allen brought me to the club and he and Chris Turner been very good to me so I wanted to repay them by showing some loyalty.
"I believe in what we are trying to achieve here and I'm looking forward to working with Dean Saunders."
Chief executive Chris Turner said: "I was delighted when Paul informed me he was staying. We are operating at a highly competitive level so it is very important that our recruitment drive at first-team level and in the youth market continues to produce results.
"I believe that in Paul, who has played a key role in the recruitment and development of players, we have one of the best in the country at what he does.
"Paul's new job title reflects his wider range of responsibilities and he will be an important figure in Dean Saunders' management team."
