Hartmann went through the ranks at Portsmouth until he was released at the end of the 2006–07 season. In his final year with Portsmouth, he went out on loan to Weymouth eventually making a total of four appearances for the club.
In July 2007, Nottingham Forest signed Hartmann on a free transfer joining as a third year academy member. By July 2008 he was released and signed for Bognor Regis Town on a free transfer and made five appearances for the club.
Hartmann received his first senior call-up in November 2006 for the 2007 ASEAN Football Championship qualification tournament in Bacolod. He made his debut in the opening match as the Philippines lost 2–1. It would be his only appearance in the tournament. Early the following year, he got a call-up to play for the Philippine U-21's in the Hassanal Bolkiah Trophy. He made two appearances, against Myanmar and Brunei.
In September 2011, he was back in the national team setup and was named in the final 20-man squad for the 2011 Long Teng Cup and the provisional Philippines under-23 squad for the 2011 Southeast Games. In the Long Teng Cup, he made his first senior appearance since his debut in November 2006, playing the full 90 minutes in the 3–3 draw against Hong Kong in the opening match.
He is the younger brother of Darren Hartmann, who has played for the Philippine U-21's during the 2005 Hassanal Bolkiah Trophy and the older brother of Mark Hartmann, who is also a Philippines under-23 and senior international footballer.
