Born in Mercedes, Soriano, Aguiar started his career with Liverpool FC Montevideo. After an impressive season he transferred to FC Porto of Portugal but, after only two months with the club, not being able to reach the first team, he was loaned out, during that season, to C.F. Estrela da Amadora and Académica de Coimbra.
On 11 April 2008, Aguiar scored in a 3–0 surprise victory for the "students" against S.L. Benfica. His very first goal in the Primeira Liga proved crucial for the Coimbra side, which finally narrowly avoided relegation as 12th.
In July 2008, Aguiar remained in Portugal, signing with rising club S.C. Braga. He was essential in helping the Minho team win 11 of their first 15 competitive matches, netting on five occasions. On 23 October 2008 he scored from a free kick in another 3–0 surprising win, this time against England's Portsmouth in the campaign's UEFA Cup.
After having been essential in Braga's qualification for the Europa League, Aguiar moved to FC Dynamo Moscow in Russia, for €2.5 millions. However, only a few months afterwards, he returned to league leaders – eventually finished second – Braga, on loan until June, eventually surpassing Hugo Viana in the club's pecking order at central midfielder. He returned to Dynamo after his loan expired, only to re-sign with the Portuguese the following month, in the same predicament.
Aguiar started 2010–11 again in the starting XI, still under manager Domingos Paciência. However, he would ironically lose his place to Viana, and left in late January 2011, returning to his country after a lengthy absence and joining C.A. Peñarol, still owned by Dynamo Moscow.
On 5 July 2011, Aguiar was sold by Dynamo Moscow to Sporting Clube de Portugal, signing a four-year contract with the Lisbon club and reuniting with former Braga boss Paciência. However, in late September, without having made any official appearances, he returned to Peñarol, again on loan.
On 27 July 2012, Aguiar moved to Argentine Primera División side San Lorenzo de Almagro on a two-year deal. He subsequently returned to Peñarol for a further three Uruguayan Primera División seasons, being loaned to Brazil's Esporte Clube Vitória in 2014.
