This is a senior, high-impact Data Science role focused on the design and evolution of credit policies across the full customer lifecycle.
You will serve as a technical reference for credit policy strategy, combining advanced analytics, experimentation, optimization, and machine learning.
The role connects Data Science with executive decision-making, translating complex data into automated and commercially effective credit strategies.
You will work closely with Risk, Fraud, Finance, Modeling, Engineering, and Product teams to balance portfolio growth with disciplined risk management.
Your work will influence approval rates, profitability, customer value, and credit risk through evidence-based policy decisions.
The environment is agile, collaborative, and highly data-driven, with significant ownership over experimentation, governance, and innovation.
This is an opportunity to shape scalable credit decision frameworks while advancing the use of AI and automation across the policy lifecycle.

Develop and maintain technical playbooks and frameworks for credit policy simulation, standardizing methodologies such as A/B testing and Champion/Challenger approaches, reusable decision-engine functions, and structured executive reporting.
Lead the design, calibration, testing, and continuous optimization of credit strategies throughout the customer lifecycle, including onboarding and origination, dynamic credit limits, pricing, account maintenance, and collections.
Apply advanced data analysis, optimization techniques, and scenario simulations, including backtesting and stress testing, to quantify the financial and risk impact of policy changes before production deployment.
Monitor active policies and strategies using business and risk indicators such as conversion rate, approval rate, NPL, overdue rates, roll rates, LTV, and risk trade-offs, recommending adjustments when performance moves outside established risk parameters.
Lead the application of decision algorithms, machine learning, mathematical optimization, and automation to evolve from rigid policies toward more dynamic and personalized credit strategies.
Integrate AI and automation throughout the policy workflow, from hypothesis generation and experimentation through production monitoring, improving operational efficiency and analytical maturity.
Act as a strategic analytical partner to Risk, Fraud, and Finance teams, translating complex data and analytical findings into clear recommendations for business and executive decision-making.
Collaborate closely with Modeling, Engineering, and Product teams to turn analytical insights and models into scalable, automated credit policies.
