Aces have already signed former Orlando Pirates coach Eric Tinkler as head coach with Ian Taylor his assistant, while Calvin Marlin remains as goalkeeper coach.
AmaZayoni, who are now under new management, are set to regroup again in Cape Town on Thursday in preparation for the new season.
Aces boss John Comitis has confirmed that Rosslee is now part of the new set-up in Cape Town.
"Yes, I can confirm that Craig Rosslee has joined us and will serve as Director of Football,” says Comitis.
Rosslee previously had a similar role as technical director at NFD club FC Cape Town, following stints as coach of Moroka Swallows and AmaZulu last season.
