• Ensure modelling inputs and outputs are robust by reviewing, shaping, and challenging data, assumptions and results to support credible decision making.
• Define and refine media frameworks and channel structures to ensure modelling reflects marketing activity and enables meaningful, decision-ready insights.
• Convert modelling outputs into commercially compelling ROI stories, including optimisation scenarios and budget allocation recommendations.
• Coordinate cross-functional teams across a globally distributed delivery model, ensuring alignment between data, modelling, and client priorities throughout delivery.

Ideal skills and experience

• Strong client management skills, with experience building trusted relationships and delivering a high-quality, effective client experience.
• Demonstrated ability to coordinate cross-functional project-based teams and manage multiple priorities in a fast-paced distributed delivery environment.
• Strong understanding of marketing effectiveness and measurement, with experience across sectors such as FMCG, Retail, Financial Services or Media.
