Selton came through the youth academy at Athletic Bilbao, joining the club at the age of ten. He featured in the 2025–26 UEFA Youth League and as a senior in the fourth and fifth tiers for CD Basconia (Athletic's farm team) prior to his debut for third-level reserve team Bilbao Athletic in October 2025 at the age of 18.

He made his professional debut for Athletic Bilbao on 5 November 2025 in the UEFA Champions League against Newcastle United, appearing as a second-half substitute in a 2–0 defeat at St James' Park. Asier Hierro also made his debut, and after the match they were congratulated by the travelling members of the Youth League squad of which Selton had been a member only a few weeks earlier. On 8 February 2026, he gave his first professional assist to Nico Serrano in the victory (4-2) against Levante UD at San Mames.

Selton was called up to the Spain under-18 national team from December 2024, without playing any official matches, before being called up to Spain U19. On 17 February 2026, he made his debut as a starter in the victory against Norway, where he made his mark in several plays of the match.
