Voja started playing rugby in 2005 at the Zemun rugby club, thanks to Milos Kucancanin. At that time he played mostly rugby union and sometimes league. Since 2010 he has been a standard member of the Red Star first team and plays at the opener position, however he prefers to play at the stopper or archer position. He played for the Serbian national team under 16 and the national team under 18, and made his senior team debut in 2012.
