Born in Santos, São Paulo, Claudinei started his professional career with Santos in 1989, but failed to make an appearance for the club. He subsequently represented Jaboticabal, Nacional de Uberaba, Mamoré, Araguari Atlético Clube, Central Brasileira Pinhalense (two stints), Caldense, Olímpia, Portuguesa Santista, São Bento, Remo, Tuna Luso, Nacional-SP and Ferroviária, retiring with the latter in 2003.
Oliveira began his managerial career as a coach at his first club Santos, joining the under-15 squad in 2009 and leading them to a Campeonato Paulista under-15 title. The following year, he was promoted to under-17s and won the Campeonato Paulista of the category. In 2011, Oliveira was assigned to the under-20s. He went on to win both Campeonato Paulista in 2012 and Copa São Paulo de Futebol Júnior in 2013; the latter came after a 29-year absence.
On 31 May 2013, after Muricy Ramalho's dismissal, Oliveira was appointed manager of the first team in Série A. His first game in charge occurred the following day, a 1–1 home draw against Grêmio, and his first victory came on 12 June, in a 1–0 home defeat of Atlético Mineiro.
Oliveira remained in charge of the main squad until the end of the season, leading the side to a seventh place overall. After being relieved from his duties and being replaced by Oswaldo de Oliveira, he signed with Goiás.
On 3 September 2014, Oliveira was appointed at the helm of Atlético Paranaense. Dismissed the following 15 March, he was named Vitória manager two days later, but was sacked on 20 May.
On 25 April 2018, Oliveira replaced sacked Nelsinho Baptista at the helm of Sport. On 12 August, after a 3–1 home loss against São Paulo, he left the club, and returned to Paraná for a third spell three days later.
