• Enable the business with data: Build and maintain Metabase dashboards and reports for marketing, sales and leadership.
• Own marketing analytics: Maintain and analyze Web (GA4), A/B testing and attribution data.
• Support financial reporting: Prepare monthly financial reporting together with finance, and help automate it over time.

• Familiarity with Git, Docker and the basics of CI/CD
• Some exposure to data pipelines or orchestration (Airflow or similar) and to BI tools (Metabase, Tableau, or similar)
