Rosa's career started with
Sarmiento of the
Primera División, after joining their academy in 2007. No appearances followed in the
2017–18 Primera B Nacional, but he returned to the first-team set-up under
Iván Delfino in
2018–19; featuring five times in the first half of the season, during which period he also netted his first senior goal versus
Platense. In July 2019, Rosa was loaned to Spain with
Peña Deportiva B; he was initially signed for their senior team, though later wasn't registered. He scored once, versus AE Santa Gertrudis, in six appearances in
Regional Preferente Ibiza/Formentera. Rosa headed back to Sarmiento in early 2020. In January 2021, Rosa completed a loan return to Spanish football with
Tercera División side
Ciudad de Lucena; the move had been delayed for months due to bureaucratic issues. He debuted in a 1–0 defeat away to
Sevilla C on 17 January. ==Career statistics==
