Nicky Law will leave Alfreton Town next month after nearly a decade in charge at the National League North side.
The 55-year-old former Grimsby and Bradford boss has accepted a role as Premier League Burnley's head of national recruitment for under 17-23s.
Law's final game will be at Gainsborough Trinity on 4 February.
He said: "It's been an extremely tough decision for me. This club is a part of me and I will never forget everything I've achieved."
