Following the end of his playing career in 2016, Harper has become an experienced coach and respected figure off the pitch, achieving his UEFA 'A' Licence, UEFA 'A' Goalkeeping Licence and a Masters of Sports Directorship degree.
He has continued to maintain close links with the Magpies throughout, serving in goalkeeper coaching roles at the Academy between 2016 and 2019 and continuing to support the Newcastle United Foundation and Sir Bobby Robson Foundation charities as a patron and trustee respectively.
He has also coached at international level, serving as goalkeeper coach with Northern Ireland's senior men’s team over 20 fixtures since March 2019.
Following a brief step away from club football, Harper returned to Newcastle United as a first team coach in November 2019 - joining Steve Bruce's coaching staff with a specific remit of enhancing the pathway between the club's Academy and senior men's team.
After being named as interim academy manager in Spring 2021, Harper has now made the position permanent and will spearhead the club's youth operations as it identifies and develops the region's best young footballing talent in preparation for the first team.
