Malacarne started his career with Argentine giants Comisión de Actividades Infantiles (CAI) from Comodoro Rivadavia, Chubut Province as a teenager.
He performed well on his debut which helped the club to a 2–0 win over the Finnish side, however it was not enough as FK Dinamo Tirana crashed out of the competition after a 3–2 aggregate loss.
Malacarne also scored an important goal for FK Dinamo Tirana in the 1st match of the 2nd qualifying leg of UEFA Champions League against Sheriff Tiraspol, after a corner kick shot by Elis Bakaj.
Malacarne has also scored a goal, again with a header against KF Skënderbeu Korçë in Qemal Stafa Stadium, as FK Dinamo Tirana won 3–0.
The goal came from a corner taken by Elis Bakaj; Malacarne managed to get his head to it and put it past the KS Teuta Durrës keeper, Bledar Vashaku.
