Undrafted, Kemppainen played nine seasons in the Finnish Liiga with Ässät, HPK and Oulun Kärpät. After his second consecutive season of 30 plus points with Kärpät in the 2014–15 season, on 21 May 2015, Boston Bruins general manager Don Sweeney announced that the club had signed Kemppainen to a one-year, two-way NHL contract for the 2015–16 season.

Following two productive seasons with Salavat Yulaev Ufa, including reaching the Eastern Conference Finals in the 2018–19 season, posting 14 points in 17 games, Kemppaninen secured a lucrative one-year contract with SKA Saint Petersburg on 1 May 2019.
Kemppainen played three seasons with SKA Saint Petersburg before leaving following the 2021–22 campaign to return to his native Finland on a one-year contract with former club, Kärpät of the Liiga, on 27 April 2022.
After recording 37 points in 67 Liiga regular-season and playoff games in 2023-24, Kemppainen sat out most of the 2024-25 season before finally announcing his retirement at age 36 on 20 February 2025.
