Ji started her career in Japan, playing for L. League champions INAC Kobe Leonessa between 2011 and 2013. In November 2013, Ji was subject to a transfer bid from English club Chelsea. She agreed to a two-year contract in January 2014. When the transfer was officially confirmed later that month, Chelsea coach Emma Hayes said of Ji: "She is one of the best midfielders in the world and our fans will love her." In one of her final matches for the Japanese club, Ji scored against her soon to be new club, Chelsea in the International Women's Club Championship final.
Ji was named Players' Player of the Year after her first season in England, as Chelsea narrowly missed out on the FA WSL 1 league title on the last day of the season. She was named PFA Women's Players' Player of the Year in April 2015 and was also named in the PFA WSL Team of the Year.
At the 2015 FA Women's Cup Final, staged at Wembley Stadium for the first time, Ji scored the only goal of the match to win the Cup for Chelsea. In October 2015 she also scored in Chelsea's 4–0 win over Sunderland which secured the club's first FA WSL title and a League and Cup "double".
Ji has represented South Korea at under 17 level and was part of the under 20 team that finished runners up at the 2009 AFC U-19 Women's Championship and third at the 2010 FIFA U-20 Women's World Cup.
In October 2006, Ji made her senior team debut while playing at the 2006 Peace Queen Cup. On 30 November 2006, she became the youngest goalscorer (15 years, 282 days) for the South Korean senior team, after scoring two goals against Chinese Taipei in the 2006 Asian Games.
Ji is the all-time top goal scorer of the South Korean women's national football team.
