Role purpose As a Scorecard Developer, you'll develop and maintain credit scoring components and associated calibrations that support approval and risk strategies across products and markets. You'll focus on building high-quality features, ensuring scores are stable and explainable, and delivering robust PD-to-bad-rate calibrations that translate model outputs into decision-ready risk measures.
Key Responsibilities
Develop and maintain scoring solutions and supporting artefacts used in credit decisioning (application and/or behavioural scoring, segmentation, risk signals)
Own feature engineering for scoring: create, test and document variables from bureau, application, transactional and repayment data; ensure stability, interpretability and data quality
Contribute to model development and tuning using modern machine learning approaches where appropriate, ensuring outputs are robust, stable and suitable for decisioning
Apply best-in-class machine learning practices for credit scoring, including disciplined hyperparameter optimisation, robust validation, and repeatable model selection workflows appropriate for production decisioning
Define and maintain feature specifications for production (definitions, transformations, edge-case handling, missing value logic, consistency checks)
Produce PD / score calibrations to observed bad rates (overall and by segment), including calibration curves, stability tracking, and recalibration recommendations
Support cut-off / limit strategy analysis using calibrated risk outputs (approval rate vs bad rate vs loss trade-offs)
Run ongoing monitoring: drift and stability of inputs/features, score distribution shifts, performance by segment and cohort/vintage, data pipeline health
Partner with Engineering / Decisioning teams to operationalise scoring outputs and ensure reproducibility (versioning, back-testing, change control)
2-4 years' experience in credit scoring / risk modelling / decisioning analytics in a lender, bank, bureau, or fintech setting
Strong SQL plus Python/R for feature engineering, analysis, monitoring and calibration work
Practical experience with advanced machine learning concepts (e.g., ensemble methods, feature selection, hyperparameter tuning, cross-validation) and the discipline to balance predictive power with stability and governance needs
Experience translating model outputs into business-ready risk measures via calibration and performance tracking
Ability to produce implementation-ready specifications and work closely with engineering/decisioning stakeholders
Nice to have
Exposure to multi-country portfolios and different bureau ecosystems
Familiarity with model risk governance, validation support, and evidence pack preparation
Experience with real-time/batch scoring pipelines and feature stores Personal attributes
Detail-oriented and quality-driven; enjoys building reliable, production-ready data logic
Practical communicator who can translate analytics into deployable specs and monitoring
Comfortable operating across analytics + implementation + monitoring Reporting line and location
