Born in Santo Tomé, Mauro graduated from Banfield's youth setup, and made his professional debut on 22 June 2008, in a 2–3 away defeat against River Plate. He was handed his first start on 26 October, in a 0–0 draw at Gimnasia LP.
After more than three full seasons with Banfield, Mauro moved abroad, signing a one-year deal with Real Murcia. He made his debut for the club on 21 August 2012, against Córdoba CF. On 24 July of the following year, Mauro renewed his link with the Pimentoneros for a further year, and scored his first professional goal on 29 September, the first of a 2–1 home win against CD Numancia.
Mauro scored his first goal in the Spanish top level on 21 September, netting his side's second in a 2–1 away win against Real Sociedad through a header. On 21 July 2015 he moved to fellow league team SD Eibar, after suffering relegation with the Andalusians.
On 11 July 2017, Mauro signed a two-year contract with CD Leganés, still in the top tier. On 26 December 2018, he terminated his contract with the club, and signed a two-and-a-half-year deal with CD Tenerife in the second division the following 8 January.
