Role purpose

As a Credit Data Scientist, you’ll use data, feature engineering and experimentation to improve credit decisioning and portfolio performance across our lending products and markets. You’ll work end-to-end from data exploration through to production-aligned features, monitoring and impact measurement.
Key responsibilities

• Analyse customer, bureau, transactional and repayment data to identify drivers of risk, loss, approval rates and customer outcomes.
• Build and iterate credit risk features and model inputs (behavioural signals, affordability proxies, stability-tested transformations), partnering closely with senior modellers and engineering.
• Contribute to development and improvement of predictive models using modern machine learning approaches, with a focus on robustness, stability and deployability.
• Design, run and evaluate credit policy experiments (cut-offs, limits, pricing/risk trade-offs, segment strategies), including post-implementation reviews.
• Develop monitoring for model/policy performance and feature health (drift, stability, segment performance, data quality checks).
• Support portfolio analytics: vintage analysis, roll-rates, migration, early warning indicators, collections funnel analytics, and loss driver deep-dives.
• Work with Data/Engineering to improve data definitions, quality, lineage and reproducible pipelines; document feature logic and assumptions.
• Contribute to governance documentation (model inputs, feature catalogues, monitoring evidence, change logs).

Requirements

Required experience and qualifications

• 2–4 years in credit analytics / credit risk / lending data science (bank, fintech, lender, bureau, consulting).
• Strong Python and/or SQL skills and experience working with large datasets.
• Proficiency in Python or R for analysis and modelling.
• Solid grounding in statistics and predictive model evaluation (ranking performance, calibration, stability) and business impact measurement.
• Exposure to advanced machine learning concepts (e.g., ensemble methods, cross-validation, hyperparameter tuning) and an understanding of how to apply them responsibly in production settings.
• Clear communication skills with technical and non-technical stakeholders.

Nice to have

• Experience with bureau data, open banking/transactional data, device/behavioural signals, or alternative data.
• Familiarity with model monitoring, governance, and documentation practices in regulated environments.
• Exposure to cloud analytics stacks (e.g., BigQuery/Snowflake/Databricks) and version control (Git based).

Personal attributes

• Curious and pragmatic; focused on measurable outcomes.
• Comfortable working in detail and iterating quickly while maintaining quality.
• Collaborative and able to work across markets and time zones.

Reporting line and location

• Reports into credit analytics center of excelence.
• Location: Mumbai, India. With collaboration with in-country lending and credit risk teams.
