[1] He made his debut for the club in a 0–0 draw with Azerbaijan's Inter Baku on 15 July 2008 in a 2008-09 UEFA Champions League qualifier, being brought on after 50 minutes by manager Boban Babunski.

Muarem moved to TFF First League outfit Orduspor ahead of the 2010–11 season, signing a contract on 18 August 2010 that was designed to keep him at the club until May 2013.

He played just twice in April and once in May under new manager Metin Diyadin and it was no surprise when Muarem's contract with Orduspor was cancelled and he returned to Rabotnicki.

After being made a free agent due to his contract with Orduspor being terminated, Muarem had offers from former club Rabotnicki Skopje and Azerbaijani side AZAL PFC.

[11] In February 2012 it was announced that Muarem had joined Azerbaijan Premier League club FK Qarabağ, signing a three–and–a–half year contract.

[14][15] Muarem made his home debut on 20 February 2012 in a 1–0 win over Kapaz PFC, again coming on as a late replacement for Bakhtiyar Soltanov.

After replacing Rashad Sadiqov with fifteen minutes of the match remaining, Muarem scored a last-minute equaliser to earn Qarabağ a 2–2 draw.

[17] A month later Muarem scored his first league goal for Qarabağ, netting a late consolation in a 4–2 loss to FC Baku on 22 April 2012.

[24] Muarem had to wait until 31 October for his next league goal; his consolation only served to reduce the deficit in Qarabağ's 2–1 loss to Gabala FC.

Despite being born in Skopje, Muarem is of Turkish descent and was eligible to play for the Turkey national team before he represented Macedonia at senior level.

Muarem made his senior debut for Macedonia under manager John Toshack in a 1–0 loss to Russia on 2 September 2011 in a UEFA Euro 2012 qualifier, coming on as an 85th-minute substitute for Veliče Šumulikoski.

[37] Following Goran Popov's injury and Mario Gjurovski's withdrawal, Muarem was named as a late addition to Macedonia's squad for friendlies against Portugal and Angola.
