- Extract insights from both structured and unstructured data.
- Build and maintain dashboards and reporting tools to monitor key business and product metrics, ensuring stakeholders have access to clear and accurate insights.
- Help design and evaluate experiments (A/B tests), including statistical analysis and interpretation of outcomes.
- Contribute to defining and refining KPIs, metric definitions, and data taxonomies that align with business goals.
- Communicate findings through clear data storytelling, visualizations, and presentations to both technical and non-technical audiences.
- Proactively identify opportunities to improve processes, uncover new insights, and drive efficiency through automation and scalable solutions.

About CloudWalk:
- CloudWalk is an AI-first fintech building its own technology to bring justice to the broken payment system in Brazil.
- Some people say a company is a unicorn when it reaches a valuation of over 1 billion dollars. We are one of those companies. But we are also a much cooler type of unicorn: a freaking amazing beast that is incredibly rare, cool as hell and damn hard to catch.
- We work in the finance sector, a very traditional field, but we try to do things differently.
Diversity and inclusion:
We believe in social inclusion, respect, and appreciation of all people. We promote a welcoming work environment, where each CloudWalker can be authentic, regardless of gender, ethnicity, race, religion, sexuality, mobility, disability, or education.
