His breakthrough came during the 2018–19 Primera División campaign, as he was an unused substitute for league fixtures with Gimnasia y Esgrima and Newell's Old Boys. Gustavo Alfaro selected the defender for his senior debut in the Copa Argentina on 19 April 2019 versus Torneo Federal A's Estudiantes, he played the full duration of a 2–0 victory. He appeared again later that month in the Copa de la Superliga versus Godoy Cruz, as they won the round of sixteen first leg away from home. After ten further appearances for Boca, including five in the Copa Libertadores, Weigandt was loaned out in 2020–21 to fellow Primera División side Gimnasia y Esgrima. In March 2024, Weigandt joined Major League Soccer club Inter Miami on loan for the duration of the 2024 season with an option to extend for another season if he played at least ten games for the team.
