Data Engineer (Product & Marketing)

Your main focus will be on the Marketing department, supporting user acquisition and growth analytics. You’ll prepare and structure data, build dashboards and reporting systems, and extract key insights to help the team understand campaign performance and user behavior.

• Build dashboards and reports to track key metrics for Product and Marketing.
• Ensure data quality and consistency across all data products.
• Analyze User Acquisition campaigns and App performance metrics (downloads, retention, LTV, conversions, etc.).
• Work closely with the Product and Marketing teams to translate business needs into actionable insights.
• Use tools like BigQuery, Looker, Mixpanel/Amplitude , and RevenueCat to collect, process and visualize data.
• Write clean, efficient Python and SQL scripts for data ingestion and manipulation.

What We’re Looking For

• Strong SQL skills and hands-on experience with Python .
• Experience working with data visualization tools (Looker, Tableau, Mixpanel, or Amplitude ).
• Solid understanding of marketing and product analytics.
• Experience in startups or product-based environments.
• A business-driven mindset and curiosity for how data drives decisions.
• Excellent communication skills and the ability to work autonomously.
• Fluent English (Spanish not required).
• Technical degree, ideally Telecommunications or similar engineering background.
• Interest in evolving towards Product or Business roles over time.

What’s Offered

• Permanent contract.
• Hybrid work model (Barcelona – Port Vell area).
• Flexible hours.
• Great working culture, young and talented team, and room for growth.
• Direct impact on the company’s growth and decision-making.
