We operate in a highly complex and ambiguous environment where: Ground truth is often unobservable (incrementality vs attribution) Clean experimentation is not always feasible Decisions must be made under uncertainty with imperfect data We build solutions for budget allocation, incrementality measurement, and bidding, enabling the business to invest each euro where it generates the highest impact. YOUR MISSION We are looking for aSenior Data Scientistto own end-to-end initiatives, shape problem definitions in ambiguous contexts, and drive decision-making through rigorous models. This role requires strong causal inference and modeling expertise, combined with the ability to influence stakeholders and translate complex marketing problems into robust, production-grade solutions. THE JOURNEY Own end-to-end marketing measurement & optimization solutions Lead ambiguous, high-impact problem spaces from problem framing to production Define success metrics and modeling approaches when requirements are not clearly specified Balance methodological rigor with business constraints and timelines Translate ambiguity into decision frameworks Convert vague marketing questions into structured, model-driven decision systems Operate in environments where experimentation is limited or infeasible, and triangulate between MMM, experiments, and observational methods Make and justify assumptions explicitly, and assess their impact on decisions Drive decision-making under uncertainty Provide clear recommendations despite imperfect measurement, articulating trade-offs and confidence levels Navigate conflicting signals (e.g., attribution vs incrementality vs MMM) Ensure outputs are actionable and aligned with real business constraints (budget caps, pacing, channel dependencies) Lead methodological design, validation, knowledge transfer Design and evolve frameworks across MMM, incrementality testing (geo experiments, synthetic control), bidding, and LTV Establish robust validation strategies in the absence of ground truth (cross-method validation, backtesting, sensitivity analysis) Set standards for statistical rigor, interpretability, and reproducibility Drive internal & external knowledge sharing across Delivery Hero and industry.

Experience dealing with incrementality, diminishing returns, and cross-channel interactions in practice. Stakeholder Influence & Communication Communicate complex statistical concepts to non-technical stakeholders Drive adoption of model-based decisions in environments with competing narratives Build trust in data products over time Engineering & Production Excellence Strong Python and SQL skills (e.g., BigQuery) Experience with production-grade practices: modular design, testing, CI/CD, version control, modern data/ML stacks. Experience leveraging agentic workflows (LLM-driven or tool-using agents) to scale data science tasks. Pragmatic Innovation Up-to-date with methods such as uplift modeling, MMM, quasi-experiments, and survival models Ability to translate advanced methods into scalable systems that deliver real business impact, not just theoretical improvements additionalInformation We believe driven talent deserves: 🍔 Monthly Glovo credits to satisfy your cravings! 🏊 Discounted gym memberships to keep you energized. 🏖️ Extra time off, the freedom to work from home two days a week, and the opportunity to work from anywhere for up to three weeks a year! 👪 Enhanced parental leave, and office-based nursery. 🧠 Online therapy and wellbeing benefits to ensure your mental well-being.
