Born in Limón, Sequeira was promoted to the first team of Deportivo Saprissa in June 2016.[2] In August 2017, after being only a third-choice, he moved abroad and signed a two-year loan deal with Spanish side Real Unión.[3]
Sequeira made his senior debut for Real Unión on 29 October 2017, in a 3–0 Segunda División B away loss against CD Tudelano. On 16 July 2019, after acting mainly as a backup, he signed a permanent two-year contract.[4]
Sequeira was part of the squad at the 2021 CONCACAF Gold Cup, but did not play any match. Originally set to make his debut in a group stage match against Jamaica, he suffered an ankle injury moments before the match and was replaced by Leonel Moreira.[9]
His debut came during a friendly match against South Korea in November 2022, when Sequeira came in as a substitute for Joel Campbell as Esteban Alvarado received a red card. Sequeira's first instant of action as a goalkeeper for Costa Rica was also his first goal conceded, as Alvarado's red card also meant a close free kick eventually scored by Son Heung-min.[10]
During the Copa America of 2024, Sequeira kept a clean sheet vs Brasil, becoming the first Costa Rican keeper to do so in 64 years, he subsequently was honored with the player of the match award.
