After winning the 2017 Scottish Junior Men's Curling Championship, Bryce skipped Scotland at the 2017 World Junior Curling Championships. He and his rink of Robin Brydone, Euan Kyle and Frazer Shaw would finish the round robin portion of the tournament with a 6–3 record, in 3rd place. In the playoffs, they would beat Norway in the 3 vs. 4 game, but lost to South Korea in the semifinal and then lost to Norway in a rematch in the bronze medal game, settling for fourth place.
