Jamie progressed through the youth ranks at Hearts before joining Cowdenbeath in the summer of 2014, with his debut for the Blue Brazil coming in an August 2015 League Cup tie against Dunfermline.
Jamie made more than 30 appearances for Cowdenbeath over the last two campaigns and has faced Thistle in competitive action when he kept goal in last season’s Youth Cup tie against the Jags.
The highly rated goalkeeper spent time on trial with Hibernian last season and joined Thistle on a two year contract.
The young ‘stopper made his first team Thistle debut at Stenhousemuir as he came on as a half-time substitute for Aaron Lennox. Sneddon kept a clean sheet.
Sneddon then made his first start for the Jags in a 5-0 win against Stranraer, making a crucial save at 0-0.
Contract Expiry: May 2020
