Santiago Wanderers Cepeda started his career in the youth ranks of
Santiago Wanderers. Nevertheless, he had a brief spell at the
Colo-Colo academy in the
Estadio Monumental David Arellano, which he abandoned due to the exhaustion generated by the constant trips between
Santiago and Curauma, where, at that time, he lived and the
Everton de Viña del Mar youth ranks between 2013 and 2016. In 2021, Cepeda was promoted to Wanderers senior team. He made his professional debut in a 2–0 defeat against
Palestino in a
Chilean Primera División match. After Wanderers' relegation to Primera B, Cepeda made sporadic appearances in the
2022 campaign but was named starter for the
2023 season, where the team failed to promote to the first-tier during the promotion playoffs finals with
Deportes Iquique.
Colo-Colo On 11 February 2024, it was announced that Cepeda signed with Colo-Colo. On March 31, he scored his first goal for the team in a 4–1 home win over
Everton de Viña del Mar, Wanderers' historic rival. Three days later, Cepeda scored his first continental goal against
Paraguayan side,
Cerro Porteño, for the
2024 Copa Libertadores. His score was an agonizing goal (90' min). Months later, on August 20, he netted a key goal against
Junior de Barranquilla in a 1–2 visit victory at
Colombia for the
2024 Copa Libertadores Round of 16.
Elche In January 2026, Cepeda moved abroad and signed with
La Liga club
Elche on a deal until 2030. ==International career==
