Jung made his national team debut on 30 January 2008 in a friendly match against Chile, conceding one goal in a 0-1 defeat. On 27 July 2008, he recorded a 85m field goal in the U-23 friendly match against Côte d'Ivoire, setting a Guinness Record, which was not broken until the Everton FC keeper Tim Howard scored a 93m goal in 2012. In the national team, Jung used to be the understudy to South Korean legend Lee Woon-jae, but Lee's retirement made Jung South Korea's first choice goalkeeper.
In the 2010 World Cup, he played in all four of South Korea's games and conceded eight goals in four matches. He has since been criticized for not communicating with his defenders well and for his seeming inability to save penalties, but since then Jung has greatly improved his goalkeeping skills and remains the top choice goalkeeper for the national team.
In the 2011 AFC Asian Cup, Jung played in all six of South Korea's games and conceded seven goals in six matches as South Korea finished in third place. In the 2012 London Olympics Jung played a vital role in South Korea's historic third place finish. He conceded just one goal in three matches in the group stage and saved a penalty kick in the quarterfinal against Great Britain. He became injured during the second half and unfortunately had to come off the pitch. Jung did not play in South Korea's semifinal match against Brazil due to his injury and South Korea lost 3–0. He returned for the third place match against Japan and kept a clean sheet as South Korea won 2–0. Jung conceded just 2 goals in 5 matches in total.
Sung-ryung, who is born in Gwangju, Gyeonggi Province, started playing football in Gwangju Elementary School and graduated Seogwipo Middle School and Seogwipo High School.
In 2003, he signed his first professional contract with Pohang Steelers. Having failed to make any appearances for the club in the first three years, he finally started to become the first choice goalkeeper, playing 15 games in 2006 and helping the club to win 2007 K League championship and be Korean FA Cup Runners up.
In February 2008, with Kim Yong-dae joining the Korean military team Jung was transferred to Seongnam Ilhwa Chunma as a replacement. and contributed to the team's 2009 K League runners-up. Ahead of the 2010 season Kim Yong-dae moved to FC Seoul and so Jung was able to keep his starting role.
On 28 January 2011, it was announced that Jung had joined Suwon Bluewings on a five-year deal for undisclosed fee. His first game was on 2 March 2011 when Jung played against Australian side Sydney FC in the AFC Champions League.
