While still a junior curler, Kim first represented her country at the women's level at the 2012 Pacific-Asia Curling Championships, playing third for Kim Eun-jung, who she also played with in juniors. There, the team won a bronze medal. The team returned to the event in 2014, where they won a bronze medal. This would've qualified them for the 2015 World Championships, but the Worlds were held in Japan who qualified over South Korea as hosts. The team would however win a gold medal at the 2016 Pacific-Asia Curling Championships, earning them the right to play in the 2017 World Women's Curling Championship in China, where they finished sixth. Also in 2017, the team won a silver medal at the 2017 Asian Winter Games.
