Monza

On 28 August 2020, Carlos joined newly-promoted Serie B side Monza on a permanent deal. He scored his first goal on 12 December 2020, in a 2–0 win over Venezia away from home. He became the youngest defender in the 2020–21 Serie B season to score a long-range goal to date. Carlos scored his second goal on 22 December, in a 2–0 win at home against Ascoli. Carlos was nominated in the Serie B Team of the Season, finishing the season with three goals and two assists. Carlos began the 2021–22 season by scoring against Cittadella in the first round of the 2021–22 Coppa Italia on 14 August 2021; the match ended in a 2–1 defeat. He was key to helping Monza gain their first promotion to Serie A, after winning the promotion play-off final against Pisa. Carlos made his Serie A debut on 13 August 2022, as a starter in a 2–1 defeat to Torino in the 2022–23 season. He scored his first Serie A goal on 9 October, in a 2–0 home win against Spezia.…

On 13 December 2018, Carlos was included in the Brazil U20 squad for the 2019 South American U-20 Championship. On 6 October 2023, Carlos was called up to the senior national team, and made his debut on 17 October 2023, in the 2026 FIFA World Cup qualification match lost 2–0 against Uruguay.

Although he initially played as a forward at age 15, Carlos struggled to adapt to the role. His positioning shifted during his tenure with the under-17 team, when he began playing as a wide midfielder. Primarily a left-back, he is also capable of operating as a centre-back in both three- and four-man defensive lines. Known for his aerial ability and defensive prowess, Carlos also possesses strong attacking qualities, particularly his crossing accuracy. Consequently, he has been described as "ideal for Italian football".

Carlos holds an Italian passport through his great-grandparents. He is affectionately nicknamed "l'Imperatore" (the Emperor) by Monza fans, in reference to Roman emperor Augustus.
