Jamie Reid made a bright start at Exeter City and made his debut in 2012 before later enjoying success in non-league football with Torquay United. He returned to the Football League with Mansfield and Stevenage and won his first cap for Northern Ireland at the age of twenty-nine in 2024. 

Jamie became a scholar/trainee in 2010 after attending South Dartmoor Community College in Ashburton. Returning from a loan spell at Dorchester, he made his debut in a league game against Oxford on Boxing Day 2012 and showed considerable promise appearing another three times in his debut season. His first goals came when he scored twice against AFC Wimbledon in April 2013. Later that year Jamie was to play twice for Northern Ireland under-21s. 

Jamie made eight league and cup appearances for City in 2013/14 without scoring and, as his early promise waned, spent a short time on loan at Torquay United (his hometown club having lived yards from the Plainmoor ground as a child) in March 2015. At the start of 2015/16 Jamie played in the EFL Trophy for the Grecians against Portsmouth before having a short stay at Truro City. Back at St James Park, Jamie scored against Bristol Rovers at the end of November 2015 and played a further twelve league and cup games that season to bring his City league tally to 23 appearances and 3 goals. He had also appeared in four cup games.  

Unbeknown at the time, as Jamie headed back to Plainmoor on loan for the 2016/17 season, this was the end of his time in the Exeter first team. Jamie was to play in all of Torquay’s games in the National League and have his loan renewed in June 2017 prior to signing a permanent deal in October 2017. The move proved a success for all parties and Jamie remained at Plainmoor until June 2020 enjoying particular success when he scored 29 times in the club’s National League South season in 2018/19. Following this up with 18 National League goals in only 32 games, Jamie was on his way back to the Football League when he agreed terms with Mansfield Town on 23 June 2020. At Torquay Jamie had appeared in 163 league games scoring 57 times, including 47 in his final two seasons. He had also scored six goals in thirteen cup matches.    

Jamie had signed a two-year contract at Mansfield where he started 31 league games in 2020/21 and scored seven league and cup goals. But he was to move to Stevenage for an undisclosed fee in July 2021. Jamie scored seven goals in thirty-eight league appearances for Stevenage in 2021/22 and, in a more prolific second season which ended in promotion, netted an 88th minute penalty as Stevenage won 2-1 at Villa Park in the FA Cup on 8 January 2023.

Having netted twenty-one times for Stevenage during the following season Jamie was included in the Northern Ireland squad for the March 2024 friendlies against Romania and Scotland. Making his full international debut nearly eleven years after playing for the under-21s, Jamie scored in the seventh minute of the 1-1 draw in Romania on 22 March 2024. Also playing in Northern Ireland's first victory over Scotland since 1983, Jamie was named in the EFL Division One team of the year in April 2024 in a season when he scored eighteen league goals from forty starts. 

Missing the start of the 2024/25 campaign because of a blood clot in his leg, Jamie regained his fitness and made further appearances for Northern Ireland against Belarus and Bulgaria in October 2024.
