Having started his footballing career with hometown's S.U. Sintrense, Loureiro went on to represent Portimonense SC, C.D. Nacional, Gil Vicente FC (making his Primeira Liga debuts in the 2001–02 season), S.C. Braga, Sporting Clube de Portugal and C.F. Estrela da Amadora, also serving uneventful abroad stints with FC Dynamo Moscow in Russia (February–July 2005) and Cyprus's Anorthosis Famagusta FC (August–December 2007).
Arguably, his biggest career moment came with Sporting: a spectacular goal, topping a great game in a 2–1 home win against S.L. Benfica during the 2005–06 campaign. However, he was never more than a utility player there, collecting only 14 appearances all competitions comprised.
On 1 November 2007, Anorthosis coach Temuri Ketsbaia called him lazy and said that he was 'still on vacation', implying that the midfielder had not yet displayed the calibre of football he was brought to the club for. Eventually, in January 2008, Loureiro and Anorthosis parted ways, and the player returned to Portugal, signing until the end of the season with northern Boavista FC.
In July 2008, after Boavista's top flight relegation, Loureiro also dropped down a level, returning to Algarve's Portimonense and being released at the end of the campaign. After one year out of football he re-joined first professional team Sintrense, in the fourth division.
Loureiro earned six caps for Portugal, all in 2003 and as a Gil Vicente player. His first came in the 0–2 loss to Italy on 12 February in a friendly match, and he last played in a 4–0 win over Bolivia on 10 June, in another exhibition game.
