Job Description

We’re looking for a data-driven explorer to turn messy, multi-modal signals into real customer magic. You’ll be digging into the dialogue between humans and LLMs, uncovering insights that drive product evolution and shape how millions interact with our AI-powered support platform.

What you'll do:

Analyze complex datasets to uncover trends, patterns, and opportunities that support data-driven decision-making in a LLM-based customer support application.

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.

The AI team:

The customer is our Lord. Everything we do must improve our customer's experience with us.

We love data and technology.

We value exploration before exploitation—curiosity comes first.

We're a mixed bag of academics and industry professionals of varied backgrounds.

We thrive in structured chaos and question every requirement.

Requirements:

Proficiency in SQL.

Fluency in Python.

Usage of LLMs as a performance-enhancing tool.

Initiative to learn, investigate, experiment, and self-manage.

Capability to communicate effectively with multiple teams, both in English and in Portuguese.

Solid Data Visualization and storytelling skills.

Ability to collect, organize, analyze, and disseminate significant amounts of information in a clear and concise manner.

Experience with unstructured data analysis.

Strong knowledge of statistical analyses and methodologies.

Nice to have:

Experience with BigQuery as a SQL and as a data warehousing service.

Knowledge of ETL frameworks like Airflow

Familiarity with trace analysis methods (Langfuse, Deepeval, Langsmith, etc.)

Experience with vector database tools like PGVector

Recruiting process outline:

Online assessment: an online test to evaluate your basic programming skills and logical reasoning.

Case: an open-ended technical case where you'll have the chance to put your abilities to test.

Technical interview and case presentation.

Cultural interview.

If you’re not interested in doing a real technical assessment or engaging in an honest conversation, don’t apply.

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.
