Giannetti debuted professionally for Vélez Sarsfield in the 2012 Clausura under Ricardo Gareca's coaching, starting in a 0–2 defeat to Argentinos Juniors. The defender was part of the squads that won the 2012 Inicial, 2012–13 Superfinal and 2013 Supercopa Argentina, although he did not play any games. Giannetti became a starter for the team during the second half of the 2015 Argentine Primera División season, in which he started in all 15 games. He scored his first professional goal in the 12th fixture of the 2016 Argentine Primera División, a last-minute winner against Argentinos Juniors. On 6 January 2024, Giannetti signed a one-and-a-half-year contract with Serie A team Udinese, with an option for a further year. On 13 August 2025, Giannetti moved to Antalyaspor in Turkey on a two-season deal.

Giannetti was part of the squad of the Argentina national under-20 football team that played the 2013 South American Youth Championship. In 2016, the defender was selected by coach Gerardo Martino for the preliminary squad of the Argentina national under-23 football team to participate in the Summer Olympics. He was later confirmed by Martino's successor Julio Olarticoechea and started in all three games of the team in the tournament.
