Born in Viamão, Rio Grande do Sul, Renan made his professional debut for Internacional against Juventude in the Campeonato Gaúcho in a 1–0 win on 3 April 2005.

He made a great start to his Valencia CF career and was their number one keeper, but on 20 January 2009 he sustained a groin injury in a match against Athletic de Bilbao and was ruled out for six weeks, enabling veteran César Sánchez to step in.

After recovering from his injury he remained on the bench till the end of the 2008–09 season owing to Cesar's fine form, and following the close season signing of Miguel Ángel Moyà from Real Mallorca he left the Mestalla.

[3] On 4 June 2010, Sport Club Internacional signed him on loan from Valencia.

[4] On 13 December 2018, Renan joined Campeonato Brasileiro Série B side São Bento on a one-year contract.
