Accountabilities

• ML and model development: Lead the design, testing, deployment, and ongoing improvement of machine learning models for credit decisioning, fraud detection, risk segmentation, customer value, monetization, and marketing attribution.
• Underwriting innovation: Develop underwriting algorithms using alternative data sources to strengthen risk assessment while responsibly expanding access to financial services.
• Real-time decisioning: Build and scale real-time or near-real-time scoring models across multiple markets and products.
• Model governance: Ensure models are interpretable, robust, fair, and reliable, with appropriate monitoring for accuracy, feature stability, performance, and drift.
• MLOps: Establish strong practices for experimentation, model versioning, deployment, monitoring, and production lifecycle management.
• Credit risk strategy: Develop and manage credit risk frameworks, policies, approval strategies, risk thresholds, and customer segmentation approaches adapted to individual markets.
• Portfolio monitoring: Track portfolio and risk metrics, investigate material changes, and establish early-warning indicators for potential deterioration.
• Experimentation: Simulate policy and model changes, lead A/B testing, and use performance data and business KPIs to continuously refine decisioning strategies.
• Stress testing and provisioning: Lead stress testing and expected credit loss modeling while partnering with Finance on provisioning and capital allocation.
• Market expansion: Develop localized risk models and policies that support expansion into new markets while aligning with applicable regulatory requirements.

• Cross-functional partnership: Work closely with Engineering, Product, and Finance to translate analytical findings into measurable business outcomes.
• External partnerships: Evaluate and establish relationships with alternative data providers and credit bureaus.
• Business impact: Improve approval rates while maintaining target default rates and responsible lending standards, reduce time-to-decision, strengthen unit economics, and identify new customer and product opportunities.
