Responsibilities

• Own production models end to end, including churn, customer lifetime value (CLV), propensity and similar customer models.
• Validate performance against holdout data and live outcomes, and monitor models for drift, bias and degradation.
• Define the data structure, entities and attribute design across each client’s full customer dataset, and document the data requirements that our Data Modeller implements and maintains.
• Identify data gaps and quality issues, and agree fixes with client and internal teams.
• Document models, features and assumptions to a standard suitable for a regulated environment.
• Explain model results clearly to non-technical stakeholders, and feed learnings back to Product to help shape the product roadmap.
