You will oversee end‑to‑end model development, collaborate closely with Data/AI & Optimization product teams, and ensure high‑quality delivery across multiple markets.

• Build advanced MMM and econometric models using our on‑prem modelling software which utilises techniques such as Bayesian regression, advanced ML, hierarchical models, & state‑space models along with standard concepts such as carryover/adstock structures, saturation curves, price elasticity and promo impact analysis.
• Own the full modelling workflow: data preparation, feature engineering, model selection, diagnostics, validation, and documentation.
• Design and apply robust QA processes (e.g., cross‑validation, holdouts, out‑of‑sample testing).
• Develop and refine media response curves and incremental ROI frameworks used in BrandDelta’s Optimiser.
• Help analyse, prepare and QA the MMM datasets (media, sales, distribution, equity, pricing, competitor, and macro).

• Work with product managers, data scientists and optimisation engineers to integrate MMM outputs into our real‑time Optimiser and LiveEquity platform.
• Help shape modelling standards and frameworks for multi‑market scalability.
• Participate in innovation initiatives - e.g., automation of MMM pipelines, integration of new data sources, or enhancements to uplift functions.
• Provide guidance and technical mentorship to analysts and junior econometricians.

• Ability to explain complex econometric concepts in simple, business‑friendly language.
• Strong communication and presentation skills for both technical and commercial audiences.
• Highly organised, detail‑oriented, and comfortable managing multiple markets and clients simultaneously.
