[5] Two years later, Bryce made his international debut at the 2019 European Youth Olympic Winter Festival, playing second on the British team that also included Hamish Gallacher, Robyn Munro and Inca Maguire.

The team, including third Scott Hyslop and lead Jack Carrick went 6–1 at the 2020 Scottish junior championship, finishing tied for first with James Craik.

[8] After the event, Bryce was invited to join Team Craik as their alternate at the 2020 World Junior Curling Championships in Krasnoyarsk, Russia.

There, the Scottish team of Craik, Mark Watt, Blair Haswell, Niall Ryder and Bryce topped the round robin with a 7–2 record, earning themselves a spot in the playoffs.

[13] Bryce and Craik reunited with former teammates Mark Watt and Blair Haswell for the 2022–23 season, forming a team to represent Great Britain at the 2023 Winter World University Games.

[14] On the European tour, the team found success, reaching the semifinals of the 2022 Oslo Cup and 2023 Mercure Perth Masters and the quarterfinals of four other events.

They then beat Ross Whyte in the semifinal before coming up short to Bruce Mouat in the final, who went on to win the 2023 World Men's Curling Championship.

[18][19] Now focused solely on men's play, Team Craik began the 2023–24 season with back-to-back playoff finishes at the 2023 Baden Masters and the 2023 Euro Super Series, losing out to Joël Retornaz and Bruce Mouat respectively.

[20] With the points they accumulated throughout the 2022–23 and start of the 2023–24 season, the team rose high enough in the ranks to qualify for the 2023 National Grand Slam event.
