Data Scientist

Job Description

Key Responsibilities

• Develop, implement, and optimize Marketing Mix Models (MMM) to measure the impact of marketing investments across channels and support budget allocation decisions.
• Build robust Bayesian statistical models for marketing effectiveness, forecasting, uncertainty estimation, and scenario planning.
• Apply causal inference methodologies to measure the incremental impact of marketing campaigns and distinguish correlation from causation.
• Design and execute advanced statistical modelling techniques including regression analysis, hierarchical Bayesian models, time-series analysis, and probabilistic modelling.
• Develop attribution and incrementality measurement frameworks using experimental and observational data.
• Conduct hypothesis-driven experimentation, including A/B testing, geo experiments, holdout testing, and lift measurement.
• Analyze large-scale marketing and media datasets to generate actionable business insights.
• Build automated dashboards and reporting solutions using Power BI or Looker Studio.
• Collaborate with Data Science, Engineering, Media Strategy, and Business teams to translate analytical findings into marketing optimization strategies.
• Build scalable Python-based analytics pipelines for model development, validation, monitoring, and reporting.
• Present statistical findings and business recommendations to stakeholders with clear explanations of assumptions, confidence intervals, and model limitations.
