Güity made his professional debut with
Olimpia on 8 April 2019, starting in the 0–0
Liga Nacional draw with fierce rivals
Motagua, filling in for the injured
Donis Escober and absent
Edrick Menjívar. On 8 August 2021, Güity was presented as a new loan singing by
Lobos UPNFM, however his parent club Olimpia disputed this and shortly after announced that Güity had in fact been loaned to
Victoria, despite Güity already having signed a contract with UPNFM. The official loan move to Victoria was made official the following 10 August. Ultimately, Güity was recalled to Olimpia one month later, as Victoria could not register him. On 28 December 2023, Lobos UPNFM was able to finalize a successful loan deal for Güity ahead of the 2024 Clausura season. He would make his debut for Lobos the following 28 January 2024, in the 3–0 home victory against
Vida. On 22 June 2025, Güity once again returned to Lobos on a season-long loan deal, after failing to register any minutes due to competition with first choice goalkeeper at Olimpia, Menjívar. ==International career==
