• Develop and maintain scorecards and risk models, incorporating behavioural indicators, customer segmentation, and risk-based approaches aligned to business risk appetite.
• Own the end-to-end model testing life cycle, including back-testing, forward-testing, and sensitivity analysis to ensure models are performant and resilient.
• Support model validation processes, providing detailed documentation, assumptions, performance metrics, and remediation actions in line with governance frameworks.
• Translate business and regulatory requirements into Quantexa configurations, data models, and analytical logic, ensuring accurate deployment into production.
• Collaborate closely with engineering, data, and architecture teams to implement and optimise models within the Quantexa ecosystem.
• Act as a key interface across Financial Crime, Compliance, Risk, and Technology, ensuring solutions meet regulatory and operational expectations.
• Drive improvements in data quality, lineage, and governance, ensuring models are built on trusted and traceable datasets.

• Proven experience in transaction monitoring scenario design within Quantexa.
• Strong expertise in model calibration and tuning (thresholds, weights, optimisation).
• Scenario modelling and rule design.
• Customer and transaction segmentation strategies.
• Hands-on experience with Quantexa platform capabilities, including configuration, data ingestion, and network-based analytics.
• Solid experience in testing methodologies (back-testing, sensitivity analysis, performance tuning).
