On 31 January 2020, Murilo was loaned to Spanish club Sporting de Gijón until the end of the season.

On 1 July 2018, shortly after Nacional’s promotion, Murilo signed a five-year deal with fellow Primeira Liga club S.C. Braga. He scored his first goal for them the following 18 January in a 3–0 win on his return to the Estádio da Madeira, having previously played seven minutes in the league all season.

On 9 June 2017, Murilo moved abroad for the first time, loaned to C.D. Nacional who had recently been relegated to Portugal’s LigaPro. He was the Madeiran club’s second top scorer behind Ricardo Gomes – fifth overall – with 13 goals as they won promotion as champions; this included braces with a late equaliser in a 3–3 draw at Académico de Viseu F.C. on 18 February and in a 6–0 home win over FC Porto B on 7 March.

Murilo returned to his home state in January 2016, joining Clube Esportivo Lajeadense on loan for the Campeonato Gaúcho season. After their relegation, he headed to Joinville Esporte Clube for three months on 4 April. The team finished as runners-up in the Campeonato Catarinense, and he scored in a 1–1 draw at Esporte Clube Comercial (MS) in the first round of the Copa do Brasil on 21 April (2–1 aggregate win).

In December 2016, Murilo left Internacional for Esporte Clube Juventude in the same state. He played seven games in the 2017 Gauchão season, scoring the only goal of a home win over Ypiranga Futebol Clube on 12 February.

In late September 2014, Murilo signed a two-year contract with Campeonato Brasileiro Série A club Botafogo de Futebol e Regatas. The team were runners-up in the 2015 Campeonato Carioca, though his input was just two substitute appearances; that September he was loaned to Macaé Esporte Futebol Clube for the Série B season, playing just three games from the bench.

Born in São José do Norte, Rio Grande do Sul, Murilo played once as a substitute for Sociedade Esportiva e Recreativa Caxias do Sul in the 2012 Campeonato Gaúcho before joining Sport Club Internacional of the same league. He made six appearances as they won the 2014 title, and scored once in a 2–1 win at Esporte Clube Passo Fundo on 26 January.
