On 16 September 2004, Smith handed in his resignation and left the club.[4] He was replaced by Roy Tunks.[5]
Smith has since worked for the Football Association as the goalkeeping coach to the England under-19 and under-17 teams and as a goalkeeping scout identifying and reporting on current and possible England goalkeepers. He has also worked as goalkeeping coach to the women's national football team.
After successfully completing a B.A. Sports studies degree in 1995, Smith also set up his own goalkeeping coaching company, Simon Smith Goalkeeping.

On 17 July 2007, Smith joined Carlisle United as a part-time goalkeeping coach.[7] On 5 August 2008, he was replaced by Dave Timmins because the club was not satisfied with his only part-time involvement at the team.[8]
Smith rejoined Newcastle in 2015 as the club's Head of Goalkeeping. He left the club in July 2022 saying "It has been a great privilege to work for Newcastle United Football Club and I have hugely enjoyed the many opportunities I've had to work with our first team goalkeepers throughout the years. I will continue watching and supporting the team and wish them every success for the future as I look forward to new challenges ahead."[9]
