- Create dashboards and data sets that drive decision-making across Sales, CX, Finance, and Marketing

- Proficiency in SQL and Python
- Direct experience with BigQuery or similar cloud data warehouses
- Comfort using AI tools in daily workflows, staying current with new models and techniques, and applying them to accelerate work
- A strong product mindset, with the ability to collaborate with stakeholders and focus on business outcomes
- Fluent in Spanish and comfortable communicating in English
➕ Nice to have
- Experience in SaaS companies with complex, multi-team data needs
- Hands-on experience with dbt, particularly projects with 50+ models in production
