Juliano debuted on TV in Alice, a series that HBO Brasil started showing in September 2008; he was an employee of a financial company that dreamed and managed to become a DJ.

[24] In 2017, he acted in the Vade Retro series as the troubled Davi[25] and then went on to work as a gold miner in the nine o'clock Walcyr Carrasco's soap opera, O Outro Lado do Paraíso.

[26] Still in 2013, Juliano starred in the feature film Serra Pelada, a super production by director Heitor Dalia that reproduced the drama of the largest gold mine in the history of Brazil.

The film has won numerous awards at festivals such as Toronto, Marrakesh and Venice, yielding positive reviews from the American specialized media.

The publication IndieWire published an article saying: "Cazarré is a movie star in Brazil and his authentic and unpretentious performance in Boi Neon should launch him on an international stage.

But if there is a unique acting style that is often undervalued in contemporary cinema, it is more likely to be Gabriel Mascaro's Boi Neon, an electric study of gender dynamics among a traveling group of rodeo hands, owes much of its power to the seductive central performance of Juliano Cazarré, who plays Iremar, a bull breeder with fashion design dreams.

Cazarré reveals little more than the basic facts about his character and speaks even less throughout the film, based on his muscular physique (and the comfort he exhibits within him) to suggest a muted machismo which tightens erotic tensions and tells a subliminal story of a free and libidinal life that does not require a single word.

"[28] Many other publications praised Juliano Cazarré's work for Boi Neon, such as Variety,[29] Hollywood Reporter,[30] The Boston Globe,[31] Chicago Tribune,[32] The Vienna Review and others.
