Smith began his career with Huddersfield Town after coming through the youth teams at Tranmere Rovers and Manchester City.
He broke his leg playing against Bolton Wanderers in 2010 which ruled him out for 12 months and on his return he was hampered by a persistent ankle ligament damage and he was informed by academy manager Andy Welsh that his contract would not be renewed.

[9] On 31 January 2015, Smith was airlifted to hospital with a head injury after colliding with the Huddersfield goalkeeper, Joe Murphy, during a 2–1 home defeat to Leeds United.
[16] The 2016–17 season proved to be a successful one for Huddersfield as they reached the Championship play-off final, Smith scoring four goals in 47 games.

[25] Smith drifted in and out of the side in 2018–19 due to the competition posed by Florent Hadergjonaj, making 16 appearances under Wagner and Jan Siewert as the team had a miserable campaign winning only three of their 38 matches and were relegated to the Championship.
[28] The team made a bad start to the season under Nathan Jones and following an EFL Cup defeat at Crawley Town in September, Smith lost his place to Tom Edwards.
[38] During a 1–0 victory over Birmingham City on 21 October 2023, Smith suffered a ruptured an Achilles tendon that would see him miss the remainder of the season.
