Mouat had a very successful junior career, winning two Scottish junior championships in 2015 and 2016. He skipped the Scottish team at the 2015 World Junior Curling Championships, where he led his team of Duncan Menzies, Derrick Sloan and Angus Dowell to a bronze medal. The team had a 6-3 round robin record, which was good enough for third place. They lost to Sweden in the 3 vs. 4 playoff game, but won in a re-match against the Swedes in the bronze medal game. Mouat would again skip Scotland at the 2016 World Junior Curling Championships, this time with teammates Bobby Lammie, Gregor Cannon along with Dowell again. The team posted a 7-2 record after the round robin, in second place. In the playoffs, they would beat the United States in the 1 vs. 2 game, and beat them again in the final to claim the gold medal.
Mouat would skip the British team at the 2017 Winter Universiade. He led the team of Lammie, Cannon and Sloan to an undefeated record en route to claiming the gold medal.
Mouat has represented Scotland at four World Mixed Doubles Curling Championships with partner Gina Aitken. At the 2013 World Mixed Doubles Curling Championship they finished 7th, in 2014 they finished 9th, in 2016 they finished fourth (their best finish to date), and in 2017 they finished in 11th place.
On the World Curling Tour, Mouat won his first tournament at the 2015 Dumfries Challenger Series along with teammates Menzies, Lammie and Cannon. He played in his first Grand Slam event at the 2016 Humpty's Champions Cup due to his winning the 2016 World Junior title. There, his rink managed a 2-2 record, before losing to Steve Laycock's team in a tiebreaker. Mouat won his second WCT event at the 2017 Stu Sells Oakville Tankard with teammates Grant Hardie, Bobby Lammie and Hammy McMillan Jr.. The team stayed in Oakville and won the Biosteel Oakville Fall Classic the following week, defeating the same team, Kim Chang-min of Korea in the final. Later on in the season, the Mouat rink would once again meat Kim in another final, this time at the 2017 Boost National. Team Mouat won the event, capturing his first career Grand Slam title, and became the youngest skip and only the second ever non-Canadian skip to ever win a men's Grand Slam event.
Until 2017 Mouat was a student at Edinburgh Napier University and is a member of the Gogar Park Curling Club.
