"We are absolutely delighted to get Jesse on board, he's an exciting young prospect," Perth Glory coach Ian Ferguson said of Makarounas, 17.
"He can play three or four different positions going forward, left or right, as the number 10 and through the middle, so he's a fantastic acquisition."
A product of the National Training Centre in Perth, Makarounas played two pre-season games for Perth Glory last season when he was just 15 years old. He has spent the last year at the Australian Institute of Sport in Canberra.
"We had him up in Newman for the game against Gold Coast and he also played against Armadale and did really well that night and scored two goals," Ferguson added.
Makarounas will 'join his new team-mates for pre-season training once he finishes his commitments with the Qantas Joeys at the FIFA U-17 World Cup in Mexico', the club said in a media release.
