What is a Marketing Analytics Specialist at Claro?

As a Marketing Analytics Specialist at Claro, you occupy a pivotal role at the intersection of data science and commercial strategy. Claro operates in a highly competitive and fast-paced telecommunications landscape, where understanding customer behavior is the primary driver of sustainable growth. Your work ensures that marketing investments are not just expenditures but strategic levers that increase customer lifetime value and brand loyalty.

In this position, you will be responsible for transforming vast amounts of raw consumer data into actionable insights that shape multi-channel marketing campaigns.
