Born in Madrid, Castro joined Rayo Vallecano's youth setup in 2015, from CD Canillas. On 25 July 2019, after finishing his formation, he signed for AD Alcorcón and was immediately assigned to the reserves in the Tercera División.

Castro made his senior debut on 25 August 2019, starting in a 1–0 Tercera División away win against Fútbol Alcobendas Sport. His first team debut came the following 26 January, after coming on as a late substitute for injured Paris Adot in a 3–1 home win against SD Ponferradina in the Segunda División.

On 23 June 2021, Castro renewed his contract with Alkor until 2025. On 27 July, he was loaned to Primera División RFEF side Celta de Vigo B, for one year.

Upon returning, Castro became a regular starter as Alkor achieved promotion to the second division, and scored his first professional goal on 5 November 2023, in a 3–1 home win over Racing de Santander. The following 10 July, after suffering immediate relegation, he moved to the Verdiblancos on a two-year deal.
