Jefferson de Oliveira Galvao was born in Sao Paulo state but began his career in the youth ranks at Cruzeiro, in the neighbouring state of Minas Gerais. Finding his opportunities at A Raposa limited after turning professional, he was loaned out to Botafogo in 2003.

Two years later he was transferred to Trabzonspor of Turkey, where he remained until 2008, while the goalkeeper also had a short spell at fellow Turkish team Konyaspor in 2008/09.

And it was not until 2009, after arriving back in his homeland with Botafogo, that the keeper really began to carve out a reputation in the minds of Brazilian fans. The following season he saved a crucial penalty taken by Adriano to seal the Rio de Janeiro state championship for O Glorioso. He also helped Botafogo lift the same trophy in 2013.

Playing for A Seleção, Jefferson was part of the squad which won the FIFA U-20 World Cup 2003 in the United Arab Emirates. As a senior player, he was called up for the first time by coach Mano Menezes in 2010 for a friendly against the United States. He was also a member of the squad for the 2011 Copa America, his first official tournament.

Come the FIFA Confederations Cup Brazil 2013, his main rivals for the No1 jersey will be the experienced Julio Cesar, currently at Queens Park Rangers, and Fluminense´s Diego Cavalieri.
