Born in Santos, São Paulo, Santos played youth football for Santos FC as a midfielder, but never played professionally. In 1999 he moved to Curitiba, and started working in a small football school in the city called Sociedade Morgenau.
In 2003, Santos joined Atlético Paranaense, being in charge of the youth squads until 2009, when he joined Coritiba's under-20 squad. In 2011 he was appointed manager of the Brazil under-15 national team, and took over the under-17s in the following year, after Emerson Ávila was in charge of the under-20s.
On 6 September 2012, Santos returned to Coritiba, now being appointed first team manager after the dismissal of Marcelo Oliveira. He was dismissed roughly one year later, and was replaced by Péricles Chamusca.
Santos was announced as manager of Bahia on 12 December 2013, but was sacked the following 26 July after nine winless matches. On 24 August, he returned to Coxa, and managed to avoid relegation with the club.
Santos was appointed as manager of Vasco da Gama on 10 December 2014, but decided not to take over to family issues and remained at Coritiba. On 8 June of the following year, he was relieved from his duties at the latter club, after four consecutive defeats.
Santos spent the following three seasons managing clubs in the Série B and in the Série C, such as Fortaleza, Figueirense, Paysandu, Londrina, São Bento and Juventude. On 16 September 2019, he returned to the top tier after being named manager of Chapecoense, seriously threatened with relegation.
