Data Analyst (Conversational AI)

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're a mixed bag of academics and industry professionals of varied backgrounds.
• We thrive in structured chaos and question every requirement.

Requirements:

• 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.
