Born in
Huarte,
Navarre, Oroz began playing football with boys in the village team
CD Huarte at the age of 6, joining the youth system at
Osasuna in nearby
Pamplona aged 12. From an early age, she was marked out as a promising talent due to her skill in the ball, creativity, and confidence. Following a year with the club's
B-team, but the club did not progress beyond the opening knockout round. In September 2018, Oroz sustained a serious injury, rupturing the
anterior cruciate ligament of her left knee during a league match against
Atlético Madrid (one of several such injuries suffered by players in Athletic's various teams over a short period) which ruled her out for the entire 2018–19 season. Along with teammate and friend
Damaris Egurrola, she decided to leave the club when her contract expired in the summer of 2020. In July 2020, after she had already agreed to join
Real Madrid Femenino, a court case regarding the legality of 'compensation lists' for players in Spanish women's football confirmed that her new employers would not have to pay a fee to Athletic Club. She immediately became a part of Real Madrid's history by being one of the 11 players to start in their first official match in October 2020 (with almost a full team of new signings, they lost 4–0 at home to
Barcelona). Two weeks later she was among the scorers in their first victory, and by March 2023 had made her 100th appearance for the
Merengues, reaching the milestone in the same match as goalkeeper
Misa Rodríguez. On 13 September 2024, Oroz signed for
Tottenham Hotspur on a four-year contract. On 21 October 2025, Tottenham announced that Oroz had suffered a season-ending ACL injury during a
League Cup game against
Birmingham City. ==International career==
