The stopper spent 20 years at St. James’ Park between 1993 and 2013, making 199 appearances and representing the Magpies in the FA Cup final, Champions League, UEFA Cup and Europa League as well as domestic games.
Following his release from Tyneside, Harper spent time at Hull City and Sunderland, but has returned home to start the next step of his career.
At the Club’s Little Benton Academy, the 41-year-old will work with goalkeepers from under-nine to under-16 level out on the training pitch, as well as helping to create a programme that develops the youngsters in a consistent manner that meets the philosophy of Newcastle United.
“I’m delighted to be working with the young goalkeepers at the Academy,” said Harper.
“I’ve been involved in grassroots football in the area for the last six years so I have extensive knowledge of the many junior football clubs throughout the region. It’s great to be back at the Club in a coaching capacity and i’m looking forward to starting.”
