About the Role

Lifesight is seeking a Lead Marketing Scientist to head a team of marketing scientists in developing advanced econometric and statistical models that solve complex marketing measurement problems. The role is anchored in scientific rigor and demands robust foundations in econometrics, causal inference, and statistical learning.

You will focus on building robust, interpretable, and scalable models — particularly in Marketing Mix Modeling (MMM) — while ensuring causal validity and statistical soundness. Beyond hands-on modeling, you will mentor a team of data scientists and shape the evolution of measurement methodologies across the organization.

Key Responsibilities

Econometric Modeling & MMM Development
Lead the design and implementation of Marketing Mix Models (MMM), formulating business problems as rigorous quantitative and statistical models.
Build models using regression-based approaches (linear and non-linear), time series methods for trend, seasonality, and forecasting, and Bayesian and hierarchical modeling frameworks.




Incorporate core marketing science constructs, including adstock and lag effects, saturation and diminishing returns, and external drivers and control variables.
Ensure statistical robustness through proper model specification, parameter stability and interpretability, and sensitivity analysis.

Causal Inference & Measurement Design
Apply causal inference methods such as difference-in-differences, synthetic control, and experimental and quasi-experimental designs.
Design and evaluate incrementality frameworks, including geo experiments and holdout testing.
Address endogeneity, confounding, and bias in observational datasets to ensure causal validity of model outputs.

Statistical Validation & Diagnostics
Perform rigorous model validation, including residual analysis and diagnostics, multicollinearity checks, and out-of-sample and cross-validation.
Evaluate model performance using appropriate statistical metrics and ensure alig
