[1] After starting his career at the comparatively late age of 14, Espírito Santo made his racing debut in single-seater machinery at the end of 2019, driving for Drivex School at Barcelona in the final round of the F4 Spanish Championship.

Despite starting out with multiple points-scoring weekends for MP Motorsport, Espírito Santo managed just two further points finishes in the season's second half, ending up 17th in the standings.

[15] The team dominated, as Espírito Santo helped them towards three victories whilst scoring four fastest laps; he ended up second in the drivers' championship after missing one race.

Espírito Santo took pole and crossed the finish line first during the opening race, though he and teammate Martin Rich were demoted to fourth after the Portuguese received a five-second penalty for overtaking under safety car conditions.

[20][21] This would prove to be preparation for Espírito Santo's main campaign, which he would contest with Cool in the ELMS alongside fellow silver-ranked driver Cédric Oltramare and Portuguese bronze Miguel Cristóvão.

Espírito Santo made a cameo in the second round of the 2024 Ultimate Cup Series in the Proto P3 class, at Algarve International Circuit, his hometrack.
