Rossi began his career in the youth system of Atlético de Rafaela. The following year, he was also an unused substitute in another Copa Argentina game against eventual champions, San Lorenzo de Almagro. On March 20, 2015, following a successful trial period, Rossi signed a professional contract with USL club Seattle Sounders Football Club 2.
He made his professional debut that same day in a 4–2 victory over Sacramento Republic Football Club, scoring once from a free-kick and assisting another.
