Cássio began playing as a left back with local side Flamengo. After missing a penalty kick in the 2001 Copa Mercosur final, his career with Flamengo was effectively over and he was loaned to Internacional and Mexican Primera División side Atlas in 2002 and 2003. While at Internacional, Cássio won the 2002 Campeonato Gaúcho and scored the club's 1000th goal in Brazilian competitions. He played in Série B with Marília during the first half of 2004, before joining Primera División Paraguaya side Olimpia in July 2004. He had a brief spell with the New England Revolution, making only three appearances before being released mid-way through the 2005 season.
Cassio's arrival at Adelaide United came after all of the club's options at left-back (Matthew Kemp, Adam van Dommele and Aaron Goulding) were either released or transferred at the end of the 2006–07 A-League season. Although failing to score during his debut A-league campaign, his 3 assists, and contribution of 14 shots on target, revealed how dangerous Cassio was as an attacking force. For his significant contributions on the field for the 2007–08 season, he was given three end of season awards, including the Club Champion award.
Despite a slow start to the 2008–2009 A-League season due to injury, Cassio proved just how valuable he had become to the club when he set up all three of Adelaide United's goals against FC Bunyodkor in the first leg semi-final of the 2008 AFC Champions League. On 15 October 2008 Cassio signed a new two-year deal with United despite interest from rival A-League clubs with the Brazilian stating that although they offered more money Adelaide was "like a second home" for the player.
Despite coming to Adelaide with a reputation of a goal scorer Cassio's first goal came midway through his second season with the club; a brilliant free kick against Melbourne Victory in late October. In December, Cassio scored a brace in Adelaide's 6–1 demolishing of Wellington with both goals coming from unstoppable drives after he cut in from the left channel.
On 3 January 2009, Cassio scored his fourth goal for Adelaide United against in the annual Sydney FC clash at Adelaide Oval. Adelaide went on to win the game 2–0. In the semi-final second leg against Melbourne Victory, Cassio was sent off by referee Matthew Breeze, and made a gesture toward the Melbourne crowd as he departed down the tunnel. In the 2009/10 season Cassio scored two goals, one from a free kick against Perth Glory and goal of the season-contender against Newcastle Jets to level the match at 1–1.
On 12 September 2011, Cassio revealed a desire to become an Australian citizen and play for the Socceroos. Cassio and his family became Australian citizens at a ceremony at Hindmarsh Stadium on 7 September 2012. As a result, he is eligible to represent Australia at international level. He also does not require a visa to play for Adelaide United, thus enabling the club to import another player on visa.
On 21 November 2012 he signed a two-year contract extension keeping him at the club until the end of 2014-15 A-League season.
