Hwang made his KBO League debut in Hyundai Unicorns in 2007. The team folded after his rookie season, and became the Nexen Heroes, for whom he played from 2008–2010. The Heroes traded Hwang to the Lotte Giants from 2010, and he continued to play for the Giants through the 2016 season. Hwang attracted international attention for a bat flip in July 2015, after he hit a game-tying home run in the ninth inning against the NC Dinos.In October 2015, Hwang announced that he had asked the Giants to post him for transfer to Major League Baseball in the United States. His teammate, Ah-seop Son, also asked to be posted. No MLB team placed a bid for Hwang.
After becoming a free agent after the 2016 season, Hwang sought a contract with an MLB franchise. On January 23, 2017, the San Francisco Giants announced they had signed Hwang to a minor league contract with an invitation to spring training for a chance to make the major league roster. Hwang began the season with the Sacramento River Cats of the Class AAA Pacific Coast League on April 8, 2017. In late June, Hwang told the Giants that he would use the opt-out clause in his contract and become a free agent if he was not called up to the major leagues by July 1. He had batted.287 with seven home runs and 44 RBIs, splitting his time between third and first base, before the Giants promoted Hwang to the major leagues. Hwang debuted for the Giants at third base on June 28. He picked up his first hit, a solo home run, on the same day. On August 31, 2017 Hwang was designated for assignment by the Giants and was outrighted to the Sacramento River Cats, the Giants AAA affiliate. He elected free agency on November 6, 2017.
On November 12, 2017, Hwang signed a four-year, $7.9 million contract with the KT Wiz. Cho Moo-geun was named as his reward player.
