Zimmerling, who played as a striker, began his career in the late 1980s, playing for Lokomotive and Chemie Leipzig in the Deutsche Demokratische Republik-Oberliga. After reunification, Zimmerling moved west, joining Hannover 96 during the 1989-1990 season. However, he failed to establish himself in the first team, and returned to Leipzig, briefly rejoining Football Club Chemie (now renamed Football Club Sachsen).
He played out the 1990s with a succession of clubs in the former Deutsche Demokratische Republik, playing for Football Club Berlin, Union Berlin (two spells), Energie Cottbus (two spells), Carl Zeiss Jena, Sachsen Leipzig for a third time, and VfL Halle 96.
While at Cottbus he played in the 1997 German Cup Final. Later in his career he moved to Austria, playing for Austria Klagenfurt followed by spells at a number of smaller local clubs.
After retirement, Zimmerling stayed in Klagenfurt, managing SAK Klagenfurt. He returned to German football in April 2009, when he was appointed manager of FSV Zwickau.
