For the 2013/14 season she was accepted into the C squad of the Austrian Ski Federation and has been competing regularly in the European Cup since this winter.

The following winter she was able to continue her old level of performance, achieved two more podium places in the European Cup and won the gold medal in giant slalom at the Junior World Championships in Hafjell on 7 March 2015.

At the beginning of the 2019/20 season, Ortlieb finished fourth behind the Czech surprise winner Ester Ledecká at the World Cup downhill in Lake Louise in December 2019.
