• Integrate experimentation outcomes (lift studies, geo tests) to improve model robustness

Data Management & Pipeline Development

• Design end-to-end MMM data pipelines - including ingestion, transformation and QC.
• Manage large, multi-source datasets (media, pricing, distribution, promotions,
  seasonality).
• Automate recurring MMM runs and ensure reproducibility of analytics workflows.

Insights & Stakeholder Engagement

• Translate complex model outputs into clear, business-friendly insights.
• Drive conversations with marketing, finance, and media teams on channel shifts.
• Present findings to senior stakeholders (CMO, growth leaders, digital teams).

• Experience with cloud data environments (AWS/GCP/Azure)
• Knowledge of optimization techniques (linear programming, gradient-based optimizers)
• Strong understanding of digital marketing KPIs across channels
• Experience working with Nielsen, Kantar, Facebook Lift, or Google Geo-Experiments data
• Exposure to MTA, incrementality testing, and customer journey analytics

Technical & Modeling Skills

• Strong econometric modeling: linear/non-linear regression, Bayesian MMM, hierarchical models
• Expertise in ad-stock, diminishing returns, saturation curves, elasticity estimation
• Solid understanding of causal inference (geo experiments, causal impact, synthetic controls)
• Experience with time-series modeling and lag structures
• Proficiency in machine learning: regularized regression, gradient boosting, hybrid MMM
• Strong statistical foundations: hypothesis testing, multicollinearity, variable selection

Data & Engineering Skills

• Advanced SQL, Python/R (stats models, PyMC, Stan, scikit-learn)
