gerente

Gerente is masculine because it derives from the Latin "gerens" (present participle of "gerere," meaning "to manage" or "to carry"). In Latin, agent nouns ending in -ens/-entis were typically masculine. When adopted into Spanish, this word retained its masculine gender despite the modern Spanish -e ending, which can be ambiguous for gender. The masculine form "gerente" is used for both male and female managers in contemporary Spanish, though it originates from and maintains the Latin masculine classification.
