Kirchen signed as a professional cyclist in 2000 with De Nardi-Pasta Montegrappa, and went on to join Fassa Bortolo in 2001. For the 2006 cycling season, he joined the T-Mobile Team following the demise of the Fassa Bortolo team.

His first recorded race was in Dommeldange in 1999, and he had to wait until 2000 for his first professional victory when he won the Piva Col trophy. Kirchen was named the Luxembourgian Sportsman of the Year in 2000, 2003, 2004, 2005, 2007 and 2008, surpassing the achievement of fellow cyclist Charly Gaul and putting him fourth in the all-time stakes.

In July 2008 he showed good form during the Tour de France, placing 8th in the general classification and wearing the coveted yellow jersey for a total of three stages. However, the following September he pulled out of the UCI Road World Championships citing a lack of form.
