As a Data Scientist in Marketing Science & Operations team, you drive the return on trivago’s marketing investment: every euro measured, allocated, and steered against the P&L. You’ll deliver real business value from complex data, working alongside peer data scientists, analysts, engineers, growth managers, and business stakeholders. You’ll own how we measure and allocate marketing spend, from attribution and incrementality to media mix modelling, and deploy models that steer real decisions. With significant autonomy and ownership, you’ll raise the bar for the wider team by sharing what you know. trivago is a place where ambition and support go hand in hand: we hold high standards and invest in each other’s growth. Apply now to join us.

How you’ll make an impact:

• Design, build, and iterate on statistical and machine learning models that shape our marketing strategy, budget allocation, and bidding decisions.
• Partner with marketing stakeholders to design ML products that solve real business problems and drive incremental value for the company.
• Collaborate with engineers and analysts to productionize models, ensure data quality, and maintain robust data pipelines across multiple sources.
• Share your findings and model results in a way that resonates with both technical and non-technical audiences, informing strategy and day-to-day execution.

What you'll need to thrive:

• Proficiency in SQL and Python, and practical experience building, evaluating, and deploying predictive models, ideally on cloud data warehouses like BigQuery and with ML ops practices such as model monitoring and versioning.
• A solid understanding of marketing metrics, attribution, campaign performance, and experimentation principles, ideally from marketing, travel tech, e-commerce, or digital growth, and ideally with hands-on A/B testing, geo testing, or causal inference.
• Strong business acumen and the ability to tell stories with data: you connect models, customer behavior, and company goals, and make complex findings clear and actionable in English, both written and verbal.
• A genuine learning mindset: you approach challenges with curiosity, seek out feedback, and continuously look for ways to develop and grow.
• A performance mindset: you set ambitious goals for yourself and have the determination and resilience to follow through and achieve them.
• An open and curious mindset toward AI: you see it as a force multiplier for analytics at scale, actively explore how it can enhance your work, and use it thoughtfully with the right guardrails
