In May 2017, Tartarotti was called up for the first team for the first time for the match against Red Bull Salzburg. He made his professional debut in July 2017, when he came on as a substitute for Patrick Salomon in the first round of the Austrian Cup against FC Dornbirn. In April 2018, he finally made his debut in the Austrian Football Bundesliga when he came off the bench for Stefan Nutz in the 86th minute of the 30th matchday of the 2017–18 season against Wolfsberger AC.
