[5] Voronov withdrew from the 2005 World Junior Championships after the qualifying round due to an injury which kept him off the ice for three months.

[7] Voronov withdrew from the 2007 Skate Canada International before the event due to a recurring foot injury.

In the 2009–10 season, Voronov was assigned to the 2009 Cup of China, where he took bronze, and 2009 Trophée Eric Bompard, where he was sixth.

Voronov was sent to Europeans but his 14th-place result led Russia to assign the country's second men's spot at the Olympics and Worlds to Russian national bronze medalist Artem Borodulin (along with Evgeni Plushenko).

Plushenko's withdrawal from the 2010 World Championships due to injury allowed Voronov to be called up as a late replacement.

This placement, along with Borodulin's withdrawal during the competition, meant Russia would have one men's berth to the 2011 World Championships.

In the 2014–15 season,[14] Voronov's first assignment was the 2014 Rostelecom Cup; he won the silver medal, behind Spain's Javier Fernández.

His first event was 2017 CS Ondrej Nepela Trophy where he won the silver medal behind his teammate Mikhail Kolyada.

Voronov started his season in mid September by competing at the 2018 CS Ondrej Nepela Trophy, where he won the silver medal behind his teammate Mikhail Kolyada.

[21] Voronov briefly coached Evgenia Tarasova / Vladimir Morozov for the duration of the 2020–21 figure skating season.

This accusation came after reigning national champion, Mikhail Shaidorov, who was not assigned to the 2021 CS Nebelhorn Trophy, the final qualifying event for the 2022 Winter Olympics.

Voronov's student, Dias Jirenbayev, was instead assigned and placed twenty-seventh, thus failing to qualify a spot for Kazakhstani men singles skaters to compete at the Olympics.

[22][23] Voronov would eventually resign from his position and became the senior coach of the Belarusian national team in June 2023.

After one year, however, it was announced that Voronov had returned to Moscow to coach at the Tchaikovsky Konyok Skating School.
