Born in Tarragona, Catalonia, Juste began his footballing career on FC Barcelona's youth ranks, moving in early 2009 to neighbouring Gimnàstic de Tarragona to complete his formation. On 20 June of that year, at just 17, he made his senior debut, playing 32 minutes in a 0–1 away loss against SD Eibar after having come on as a substitute for Nebojša Marinković.
In the 2011–12 season, with the club still in the second division, Juste was promoted to the first team – after playing several years with farm team Pobla de Mafumet CF – after an injury crisis, and started the first match of the season on 20 August, against Real Valladolid. In late June 2012, after Nàstic suffered relegation, he returned to his first club Barcelona, signing a two-year contract and being assigned to the B-side; however, on 15 July, Nàstic announced that he would return to the club for preseason play.
On 6 August 2012, Gimnàstic and Barça reached an agreement for Juste, and he signed a three-year deal with a €12 million buyout clause. He picked up an injury in mid-August, only returning on 8 January 2013; however, on the 17th, he went down with a knee problem, being sidelined for the rest of the season.
On 20 August 2013 Juste damaged his anterior cruciate ligament, going on to miss a further several months. He finally made his debut for Barça B on 31 May of the following year, playing the last three minutes of a 4–3 home win against AD Alcorcón.
Despite appearing rarely, Juste was named B-team's captain on 22 August 2014.
