After impressing in pre-season trials with Sydney FC, including a goal against Manly United, he was announced as a new signing on 25 June 2009 for the upcoming 2009–10 season, on a two-year contract. His good form made him a crowd favourite amongst the Sydney fans. He is a quality left back who likes to get forward in attack. His two-footed crossing ability is a key to his game. It is noted that he is a fast player – prior to 2005, he could run the 100m in 12.2 seconds. He is known for his attacking abilities and speed.
Byun scored the winning goal and his first professional goal, for Sydney FC in the penalty shoot out of the 2009/10 Grand final against Melbourne Victory. Sydney FC released Byun at the end of the 2010–11 A-League season, deciding not to extend his contract for the Asian Champions League.
After being released by Sydney, Byun entered into negotiations with fellow A-League club Newcastle Jets. And on 11 April 2011 it was announced that Byun had signed a one-year contract with the Jets.
Byun scored on his A-League debut for the Jets, sealing a 3–2 victory over Melbourne Heart in Newcastle. This was Byun's first goal in open play, after 146 games in professional competition. In the Round 14 game against Melbourne Victory Byun scored two own goals to give the Victory a 2–1 win at AAMI Park. On 8 December 2011 the future of Byun was uncertain after routine medical tests revealed a potentially serious heart condition. The test revealed that he had a left ventricular hypertrophy (enlarged left ventricle).
