Curiel was born into the prominent Curiel family, who held diplomatic positions across central Europe. He was the uncle of Alonso de Curiel through bis brother Diego de Curiel, who was also an influential merchant. Curiel started his career between Madrid and Brussels, furthering trade for the Spanish Empire. In 1560, he was appointed Agent of Felipe II of Spain in  Antwerp, the Netherlands. Curiel's influence reached its height under Margaret of Parma, who recommended that Curiel be created the King's head of the Treasury in 1567. With the arrival of the Duke of Alba in Flanders, Curiel saw his position diminish as the Duke forced out those with whom he disagreed. In 1569, Curiel and Francisco de Ibarra attempted to tarnish the Duke's reputation in a report for the King.

Curiel left Flanders to serve as the King's Agent in  Paris, with little of the great influence that he had enjoyed in the Netherlands.
