Remiro made his professional debut on 24 August 2015, starting in a 0–1 home loss against Girona FC.[5] In June 2016, he was promoted to the first team in La Liga.
Remiro was loaned to second-tier side Levante UD on 1 July 2016, for one year.[6] He was recalled by his parent club late into the following transfer window, however, due to an injury to Kepa.[7]
On 21 July 2017, Remiro moved to division two's SD Huesca on a one-year loan deal.[8] He played a major role in the Aragonese club achieving promotion to the top flight for the first time in their history, only missing one game in 42.[9][10]
On his return to the San Mamés Stadium, Remiro seemed set to play in the first team after Kepa moved to Chelsea and the other established goalkeeper Iago Herrerín sustained an injury.[10] However, his representatives failed to agree on the terms of a new contract with the club, and in response his understudy Unai Simón was selected to play in the first match of the new campaign against CD Leganés;[11] with Simón becoming established in the team and no resolution to the contractual dispute, some weeks later it was confirmed that Remiro wished to leave Athletic and would be allowed to do so on 30 June 2019.[12]
Real Sociedad
Remiro agreed to a four-year deal with Athletic rivals Real Sociedad on 10 June 2019, effective as of 1 July.[13] He made his league debut on 27 September, keeping a clean sheet in a 3–0 home victory over Deportivo Alavés.[14]
In May 2020, Remiro tested positive for COVID-19.[15] The following 3 April, he started in the delayed final of the Copa del Rey, helping to defeat his first club Athletic 1–0 in Seville.[16][17] On 31 October, he was consoled by former teammates at the end of another Basque derby due to his obvious distress after conceding a late equalising goal with a mistimed attempt to punch the ball clear, when a victory would have put Real Sociedad clear at the top of the table.[18]
Remiro played all 38 league matches in 2022–23 (50 overall), with Real finishing fourth and qualifying for the UEFA Champions League.[19] His maiden appearance in the competition took place on 20 September 2023, in a 1–1 group-stage home draw against Inter Milan.[20]
On 15 March 2024, Remiro was picked for friendlies with Colombia and Brazil to be held later that month.[23] He won his first cap seven days later, coming on as a 46th-minute substitute for David Raya in the 1–0 loss to the former in London.[24] He was included in the squad for the Euro finals alongside Simón and Raya,[25] failing to make an appearance for the champions.[26]
