Most of his 16-year professional career was associated with Vitória de Guimarães, which he represented in three different spells, appearing in nearly 250 official games.
Born in Ribeira de Pena, Vila Real, Meireles began his professional career with Vitória de Guimarães, having no impact whatsoever at the club in his first spell and moving to the lower leagues in 1996, first with Moreirense FC (where he also appeared very rarely, in the second division) then A.D. Fafe.
In 1999, he returned to Vitória, meeting the same fate, and quickly moved again to Fafe. The following season, he switched to another former club, Moreirense, being instrumental as the club – also based in Guimarães – promoted from the third level to the Primeira Liga in only two years, under manager Manuel Machado.
For the 2003–04 campaign Meireles re-joined Vitória de Guimarães, for a third spell: his first game came on 18 August 2003, playing the entire 1–0 home win over U.D. Leiria. At the Minho side, he was now an automatic first-choice and team captain from the start, helping it achieve promotion in 2007 and qualifying to the UEFA Champions League in the following season, with the player appearing in all but two games and scoring three goals; in two different stints with the club, he was again coached by Machado.
On 22 May 2011, after appearing in the Portuguese Cup final against FC Porto, 34-year-old Meireles announced his immediate retirement from football. Shortly after, he was appointed as a coach at the club.
