BK Mladá Boleslav
Rittich made his Czech Extraliga debut with BK Mladá Boleslav during the 2014–15 Czech Extraliga season. After two successful performances in the ELH, Rittich was signed to a one-year, two-way contract on 10 June 2016, with the Calgary Flames of the National Hockey League (NHL).
Rittich made his NHL debut against the San Jose Sharks in the third period of the Flames' final regular season game of the year. He made 9 saves on 10 shots after replacing Brian Elliott in the third period to finish the game with a 3–2 loss.

In December 2017, the Flames traded their backup goaltender Eddie Läck away, making Rittich a full-time NHL goaltender for the first time as the backup to Mike Smith. In his first season with the club, Rittich finished with an 8–6–3 record.
