Having made his senior debut for East Bengal, Majumder endured the heartbreak of two runner-up medals in the 2011/12 I-League and Federation Cup.
Subsequently he moved to Bhawanipore, a team in the second division of the I-League in 2012. Notably, the team came within a point of qualifying for the first division, narrowly losing out to Royal Wahingdoh. Nevertheless, his efforts behind the goal drew attention, with his transfer to East Bengal’s arch-rivals Mohun Bagan for the 2014/15 season and with six clean sheets in 14 matches helped the Maroon Brigade triumph. He made two appearances for Mumbai City FC in Hero ISL 2015 and will spice up the competition for the goalkeeping spot in the ATK camp this year.
