Real Sociedad
Born in Lodosa, Navarre, Martínez joined Real Sociedad from local CD Izarra, aged 13. He made his senior debut with the former's B team, going on to spend two full seasons in the Segunda División B.

In the 2007–08 campaign, with the main squad in Segunda División after 40 years, Martínez started competing as a professional.

Martínez contributed 23 games – 22 starts – in 2009–10 as the Txuriurdin returned to La Liga after three years, as champions. He made his debut in the competition on 29 August 2010 by featuring the full 90 minutes in a 1–0 home victory over Villarreal CF; in the following seasons, he battled for first-choice status with fellow youth graduate Dani Estrada.

In May 2018, after he made only a single Copa del Rey appearance since December 2016 due to injuries and the form of the emerging Álvaro Odriozola in his position, the club announced that Martínez would be departing from the club on the expiry of his contract at the end of the campaign, at the same time as long-time teammate Xabi Prieto.

On 6 July 2018, Martínez signed a one-year deal with Real Oviedo in the second division. On 9 August 2019, he moved down one tier and joined Burgos CF; the following 15 January, he terminated his contract by mutual consent.
