Jack became a trainee in 2019 and, in the December of that year, was on the bench for Exeter City’s first-ever league meeting with Salford City. He was an unused substitute on five subsequent occasions that season.

During 2021/22 Jack spent two periods on loan with North Devon clubs switching from Bideford to Barnstaple in October 2021.  Jack was playing for Crediton United in the SW Peninsula League during 2022/23 and also appeared for Plymouth Parkway in March 2023.  He was subsequently a member of the Crediton team that defeated City in the Devon St Luke's Bowl in September 2023 before following joint managers Ben Watson and Jack Furzer to Barnstaple Town.
