Kuzmenko made his
Kontinental Hockey League debut playing with
CSKA Moscow during the
2014–15 KHL season. In the
2017–18 season, Kuzmenko broke out as a 21-year-old establishing career bests of 13 goals and 25 points in 45 games with CSKA. In helping the club reach the
Gagarin Cup finals, he produced four goals in 15 games. Approaching the

SKA Saint Petersburg in exchange for

2021–22 season, Kuzmenko increased his offensive output to over a point-per-game leading SKA in scoring with 20 goals and 33 assists for 53 points in 45 regular season games. He led the team in the postseason, continuing his scoring pace with 14 points in as many contests before losing in the Conference finals to eventual champions and former club, CSKA Moscow. As an undrafted free agent and having gained NHL interest, on June 20, 2022, Kuzmenko was signed to a one-year, entry-level contract with the
Vancouver Canucks. He made his NHL debut on October 13, where he scored a goal in the eventual 5–3 loss to the
Edmonton Oilers. He continued to produce steadily through the early parts of the season; on November 3, he recorded his first career NHL hat-trick in a four-point game, as the Canucks took an 8–5 victory over the
Anaheim Ducks. By this time, Kuzmenko had tallied six goals and four assists for 10 points through 11 games. Establishing himself as one of the Canucks top offensive contributors, Kuzmenko as an impending free agent opted to remain with the Canucks in signing a two-year, $11 million contract extension on January 26, 2023. On January 31, 2024, in the midst of a struggling sophomore season that saw him get healthy scratched multiple times, Kuzmenko, along with multiple draft picks and prospects, was traded to the
Calgary Flames in exchange for forward
Elias Lindholm. On January 30, 2025, Kuzmenko, along with
Jakob Pelletier and two draft picks, was traded by the Flames to the
Philadelphia Flyers in exchange for
