The 43-year-old, who played for SC Freiburg, SV Werder Bremen and VfB Stuttgart, last worked as sporting director at VfL Bochum up to April.
Experience with youth
After hanging up his playing boots, Todt worked as head scout for Hertha Berlin before taking charge of Hamburger SV's youth academy, continuing in a similar role at VfL Wolfsburg prior to his move to Bochum in 2011.
"Jens Todt is a perfect fit for the profile we had drawn up for this position," said Karlsruher's president Ingo Wellenreuther. "He's gained knowledge of professional football over the years, both on and off the field, and he has a good network. Furthermore, we are in total agreement when it comes to our youth development concept, which is something with which he has a wealth of experience."
Todt fills the void left by the departure of Oliver Kreuzer to HSV at the start of June. "We felt from the very beginning that we were on the same wavelength," added Wellenreuther. "We believe Jens Todt fits in very well with KSC and our team."
