Janker started out in 1860 Munich's youth system. He eventually made his debut in the 2. Bundesliga, and became a regular for their reserve team. After asking for a transfer to another team, he joined TSG 1899 Hoffenheim.
In 2009, Janker and his team member Andreas Ibertsberger came under investigation after failing to report to a doping control promptly after the match against Borussia Mönchengladbach on 2 February 2009. The German Football Association (DFB) suspended the investigation due to the lack of evidence, also Janker was later tested negative. The investigation was widely covered by the German press. On 23 May 2009 after the Bundesliga final, he announced his departure at the end of the season on 30 June 2009.
On 28 May 2009, Janker signed a three-year contract with Hertha BSC. In Berlin, Janker struggled to establish himself, sitting on the bench more often than not in his first season for Hertha. At the end of the 2009–10 season, Hertha were relegated to the 2. Bundesliga. In the second division, Janker fared even worse. He made only one start, and came on off the bench a further three times. Back in the Bundesliga for 2011–12, Janker made eighteen appearances.
