Born in Alboraya, Valencian Community, Giner grew in the youth ranks of local Valencia CF.
Giner's first match as a professional took place on 23 August 2015 (one month shy of his 27th birthday), when he started in a 2–2 home draw against Albacete Balompié.
[6] On 31 August 2017, he joined third-tier club RCD Mallorca,[7] being sidelined for the remainder of the campaign after suffering a knee injury in November.
He managed only eight appearances subsequently (six as a substitute, one goal against Real Oviedo in the second round of the Copa del Rey),[10] terminating his contract the following 28 January and moving to UD Ibiza shortly after.
[11] On 20 June 2019, Giner reached an agreement to sever his ties with Ibiza,[12] and returned to Nàstic seven days later after agreeing to a two-year deal.
