Born in Irun, Gipuzkoa, Basque Country (Spain), Merquelanz joined Real Sociedad's youth setup in 2012, from Antiguoko.[2] He was promoted to the reserves on 23 June 2014,[3] and made his senior debut on 31 August by coming on as a second-half substitute for Pablo Hervías in a 3–0 Segunda División B away loss against CD Tudelano.
Merquelanz scored his first senior goal on 20 September 2015, netting the second in a 5–0 away routing of CD Mensajero. Roughly one year later, he scored a hat-trick in a 4–0 home thrashing of Gernika Club, and finished the 2016–17 campaign with ten goals in 36 matches.
Merquelanz renewed his contract until 2019 on 17 May 2017,[4] but suffered a serious knee injury in December, which kept him out for the remainder of the campaign.[5] The following 12 January, he extended his contract until 2020.[6]
On 14 August 2018, Merquelanz was definitely promoted to the main squad in La Liga.[7] He made his debut in the category on 31 August, replacing Asier Illarramendi in a 2–1 away loss against SD Eibar, but being taken off three minutes later due to an injury.[8]
On 19 July 2019, after spending the campaign nursing his knee injury, Merquelanz joined Segunda División side CD Mirandés on loan for one year.[9] He scored his first professional goal on 24 August, netting the equalizer in a 2–1 home loss against Cádiz CF. Merquelanz was a regular starter for the Castilian-Leonese side, scoring a career-best 15 goals and helping the club avoid relegation and reach the semi-finals of the Copa del Rey.
Upon returning to Real Sociedad, Merquelanz agreed to a contract extension with the club until 2025 on 8 August 2020.[10] Roughly one year later, after featuring sparingly, he was loaned to fellow top tier side Rayo Vallecano for the season.[11]
In September 2021, Merquelanz suffered another knee injury during a match against Levante UD,[12] being sidelined for the remainder of the campaign. He suffered a setback from his injury in May 2022, which led him to miss the entire 2022–23 season,[13] and underwent a new surgery in June 2023.[14]
Merquelanz returned to trainings in December 2023,[15] but still failed to feature a single minute during the 2023–24 season after being unregistered. He terminated his contract with the Txuri-urdin on 23 July 2024,[16] and agreed to a one-year deal with SD Eibar in the second division the following day, subject to a trial period.[17]
On 3 October 2025, free agent Merquelanz signed a one-year deal with FC Andorra also in division two.[18] The following 12 January, after just two matches, he left the club.[19]
