A product of Athletic Bilbao's famed youth system, Garmendia made his first-team debut in 2006–07's first matchday, in a 1–1 local derby with Real Sociedad. During his three-year professional spell with the Basques, he never appeared in more than 18 La Liga games; he scored his first goal in the competition on 10 December 2006, helping to a 4–2 home win against Recreativo de Huelva.
In late July 2009, Garmendia bought out the remaining year of his contract and moved to second division club CD Numancia in a 2+1 contract – former Athletic teammate Iñigo Vélez also made the move. He continued competing in that level in the following years, with Girona FC and CD Mirandés, suffering an anterior cruciate ligament whilst at the service of the former that sidelined him for several months.
