He made his professional debut on 5 November 2014 during a win over Boca Unidos, which was the first of thirty-two appearances in his opening three seasons. In his fourth, he netted four goals throughout the year; notably the first against Villa Dálmine in April 2017. In January 2018, Mainero completed a transfer to Argentine Primera División side Vélez Sarsfield. His first appearance in the top-flight came in a 2–0 defeat to Chacarita Juniors on 5 February.

He made twelve appearances in all competitions whilst scoring two goals; in the league versus Talleres and Rosario Central. His 100th career appearance arrived on 3 March 2020 in the Copa Libertadores versus Santos; in what was his last match for Defensa due to the COVID-19 pandemic. He featured for Vélez on 31 October versus Huracán, before departing on loan in November to Chilean team Deportes Iquique. After debuting against Cobresal on 23 November, Mainero scored on 8 December versus Unión Española.
