Data Engineer (Product & Marketing)

Overview

We are collaborating with a fast-growing tech startup based in Barcelona, founded by experienced entrepreneurs in the mobile and AI industry. Their mission is to build the next generation of AI-powered mobile business apps, and they are now looking for a Data Engineer to join their team.

The Role

You’ll be the data engine behind the company — the person responsible for setting up, maintaining, and improving the entire data infrastructure that powers marketing and product decisions. 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. This is not a purely technical position — we’re looking for someone who enjoys connecting data with business impact, and who may be interested in growing towards Product Management or Product Analytics roles in the future.

What You’ll Do

• Design, maintain and improve the company’s data infrastructure (Google Cloud).
• 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.
