Early life
Yoon is the younger of two children and only daughter of retired baseball player and coach Yoon Hak-kil. She was born and raised in Busan as her father was a "one-team man" who spent his entire playing career and part of his coaching career with Lotte Giants. Her father had been initially opposed to her becoming a professional athlete but relented after much persuasion.

Yoon was initially a taekwondo athlete in elementary school before switching to fencing in middle school. As a high school student, she participated in the 2010 Junior World Fencing Championships.

Career
Yoon was first selected for the senior national team in 2011 and won individual gold at the 2012 Asian Championships. She did not participate in the 2012 Summer Olympics as the women's team sabre was not in rotation and she was not ranked high enough to be selected for the individual event. In 2014, she was part of the team along with Kim Ji-yeon, Hwang Seon-a and Lee Ra-jin and they won silver at the Asian Championships and gold at the Asian Games.

Yoon won her first ever Fencing World Cup medal in October 2015, at the Orléans competition. She was joint bronze medalist with Ibtihaj Muhammad. At the 2016 Summer Olympics, she only participated in the team event but they failed to win a medal after losing to Ukraine at the first stage. She won her first World Championships medal when they won silver in the team event at the 2017 World Championships.

Personal life
Yoon attended Dong-Eui University, one of the few universities with a fencing team, and was contemporaries with fellow sabre fencer Kim Jun-ho. She is enrolled as a graduate student at Kookmin University, studying sports psychology.
