Stangl joined Sturm Graz in 2001, and having advanced through the club's youth system made his debut for the second team in a 4–2 defeat by SC Weiz in Regional League Central on 2 June 2009. He made his first-team debut as a late substitute in a Champions League qualifier against FC Zestaponi of Georgia on 26 July 2011.[2] After making three further appearances for Sturm Graz, Stangl was loaned to First League side SV Grödig in January 2012.[3] He left Sturm Graz in the summer of 2012 to join SV Horn, where he established himself as a first-team regular in the First League. He joined SC Wiener Neustadt of the Bundesliga a year later.[4]
In summer 2014, he moved to Rapid Wien signing a contract until 2017. At the occasion of his signing, Rapid's general manager Andreas Müller described him as "strong in the air" and "standing out by his competitive spirit".[5]
