Ng was discovered through a talent search programme School Belle and the Beau hosted by MediaCorp DJ and Host, Dennis Chew and Belinda Lee, during his university days.[4] They were filming the variety show at National University of Singapore where Ng studies at and his performance and looks caught the attention of the producers at MediaCorp. Ng was then given a supporting role in the 2005 series A Life of Hope where he acted alongside Joanne Peh, and after the airing of the series, MediaCorp offered Ng a contract with them.
He won the Rocket Award for the biggest breakthrough at the Star Awards 2010 after earning a Best Actor nomination for his performance as a young man with autism in the series Breakout and also he was nominated for best on-screen couple with Zhou Ying in the same year.
In 2008, Dai Xiangyu replaced him, who was originally selected but was injured just prior to the filming, to play the role of Yamamoto Yousuke, in the drama series, The Little Nyonya.
