• Implement robust validation, monitoring, and performance frameworks.
• Translate business and risk requirements into advanced analytical solutions.
• Work closely with actuarial, risk, and engineering teams to operationalise models.

Skills & experience:

• Strong commercial experience delivering ML models into production environments.
• Advanced Python (essential).
• Experience within Financial Services or other regulated environments.
• Strong predictive modelling expertise (regression, classification, ensemble methods).
• Risk modelling experience (e.g. pricing, credit risk, claims, underwriting).

• Ability to communicate effectively with senior stakeholders.
