Following a one-year loan to fellow Cretan Delta Ethniki side PANOM, Kiliaras signed his first professional contract with the club in the summer of 2007.
[1] After a brief loan spell to Gamma Ethniki side Trikala in the winter of 2010,[2] Kiliaras left Ergotelis in the summer of 2010 having made a total of 11 appearances and having scored 1 goal.
He returned to Ergotelis and the Super League in 2013,[4] but left in September 2014, after a falling out with the club's board of directors following a loan deal refusal.
After one season with Irodotos, Kiliaras signed with Cretan former renowned club OFI, who had been relegated to the Gamma Ethniki following its withdrawal from professional competitions.
Being one of the last players in OFI's Super League roster still remaining from the club's years in the third Division, Kiliaras received substantially less playing time in top-flight, and was eventually released from his contract in the winter of 2019.
