Majorov is coached by his parents. He is originally from Russia, but he moved as an infant to Sweden as his parents started coaching there. His younger brother Nikolai competes at the international junior level in figure skating. Majorov is the first skater from Sweden to medal at the ISU World Junior Figure Skating Championships (bronze in 2011) and the first Swedish figure skater to medal at an ISU Championships since Vivi-Anne Hulten won the bronze at the World Championships in 1937. He holds a diploma as a physiotherapist and plans to retire from competing following the 2018/19 season.
