Born in Berlin, Hartmann started his professional career with Hertha BSC, making his first appearance on 31 July 2008 in the 2008–09 UEFA Cup first qualifying round second leg against Nistru Otaci. He made his Bundesliga debut on 17 August 2008 in the opening fixture against Eintracht Frankfurt when he came on in the 67th minute to replace Gojko Kačar.

In June 2011, Hartmann signed for the 2. Bundesliga club Alemannia Aachen.[3] Failing to make a single appearance in six months, Hartmann left Aachen in January 2012 to join 3. Liga club SV Babelsberg 03.[1] He left Babelsberg in July 2013 after the club were relegated to play for Berliner AK 07 in the Regionalliga Nordost, and in the summer of 2014, joined Tennis Borussia Berlin in the sixth-tier Berlin-Liga.[4]
