Sette Câmara began racing in karting before making his Formula 3 Brasil debut in 2014 at age sixteen, the minimum legal age. He also appeared at Imola that year as a guest driver in European F3 with EuroInternational.
In 2015 he joined Motopark for a full European F3 season, earning his first European podium at Spa and finishing 14th overall. At the Macau Grand Prix that year, racing in his debut around the street circuit, Sette Câmara recorded a fastest lap more than 1.5 seconds faster than his own qualifying time — an outright lap record for the Macau circuit at that time. He also competed in the Toyota Racing Series in New Zealand, placing twentieth.
Red Bull signed him to the Red Bull Junior Team in 2015, and he made an initial F1 test appearance with Toro Rosso after the British Grand Prix at Silverstone. He also made his official test debut at Motorland Aragón.
Returning to European F3 with Motopark in 2016, Sette Câmara showed consistent pace despite several grid penalties and other setbacks, finishing eleventh in the championship. He returned to Macau with Carlin, and finished third in a race that featured an intense late battle involving Antonio Felix da Costa and Felix Rosenqvist.
In 2017 he was dropped from the Red Bull program but remained competitive at Macau. He entered the 2017 Macau Grand Prix and led the closing stages, looking set for victory until he was overtaken on the final corner by Ferdinand Habsburg. Both cars contacted the wall and Sette Câmara failed to reach the checkered flag, being classified thirteenth after leading most of the race.
Sette Câmara joined MP Motorsport for the 2017 FIA Formula 2 Championship. After a scoreless first half of the season, his fortunes turned at Spa-Francorchamps. Starting third in the sprint race, he led from turn one to take his first car-racing victory. He backed it up with second at Monza the following week. He closed the season with points finishes at Yas Marina, ending the year with enough momentum to return for 2018.
In 2018 he drove for Carlin in Formula 2, finishing second to Lando Norris in the opening feature race in Bahrain and accumulating eight podiums across the season to finish sixth in the championship. McLaren signed him as a development driver in late 2018 for the 2019 season, though he returned to the Red Bull program in 2020.
Sette Câmara joined GEOX Dragon as reserve driver in early 2020, setting the second-fastest time at the Marrakesh rookie test. When Brendon Hartley departed mid-season, Dragon promoted him to a race seat for the Berlin season finale in the 2019–20 season.
For 2020–21 he was confirmed as a full-time Dragon driver alongside Nico Müller. He scored his first Formula E points with a fourth-place finish at the Diriyah ePrix, Dragon's best result since the 2019 Swiss ePrix. He ended the year 22nd in the standings. For 2021–22 he was joined by Antonio Giovinazzi, and scored a single points finish with ninth at the London ePrix.
Sette Câmara switched to NIO 333 for the 2022–23 season alongside Dan Ticktum. His best result was fifth at the chaotic Hyderabad ePrix, the team's strongest finish since 2018. He ended the year twentieth in the championship. The team rebranded as ERT Formula E Team for 2023–24 and retained both drivers before releasing Sette Câmara at season's end.
After losing his ERT seat, Sette Câmara joined Nissan as reserve and simulator driver for 2024–25. He substituted for Norman Nato at the Berlin ePrix when Nato had conflicting WEC commitments.
In 2025, Sette Câmara signed with Nielsen Racing to contest the European Le Mans Series alongside James Allen and Anthony Wells.
Sette Câmara's career is defined by flashes of genuine speed — the 2015 Macau lap record, the 2017 sprint win at Spa, consistent podiums in Formula 2 — alongside a series of near-misses and team changes that kept him from a sustained frontrunning role. His near-win at the 2017 Macau Grand Prix, lost on the final corner of the final lap, remains one of the more dramatic might-have-been moments in that event's recent history.
