Porto

On 17 July 2018, Mouandilmadji signed a four-year contract with Porto.

Mouandilmadji made his professional debut for the Primeira Liga title holders on 11 August as an 81st-minute substitute for fellow Coton Sport graduate Vincent Aboubakar, and scored the final goal of a 5–0 home win over Chaves. He then dropped down to the second team in LigaPro, and scored both of their goals of a 2–1 win over Cova da Piedade on 11 November. On 9 January 2020, Mouandilmadji was loaned to last-placed Aves for the rest of the top-flight season. After their relegation, he was named in Porto's first-team squad for 2020–21. He rescinded his contract by mutual consent in January 2021, with 18 months remaining.
