Data Scientist (Credit Analytics)

The Data Scientist will play a pivotal role in assessing, analysing, and mitigating credit risks within the MCA SA Credit Analytics team at GoTyme. Working end-to-end from data exploration through to production-aligned features and monitoring, the candidate will use data, feature engineering, and experimentation to improve credit decisioning and portfolio performance for the Merchant Cash Advance product.

Credit Risk Modelling

• Develop, implement, and maintain acquisition scorecards and models to evaluate MCA applicants
• 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 the development and improvement of predictive models using modern machine learning approaches, with a focus on robustness, stability, and deployability
• Monitor provision models aligned with regulatory and accounting standards
• Enhance portfolio monitoring tools and dashboards to track credit performance and early warning signals, including drift, stability, segment performance, and data quality checks

Data Analysis & Insights

• Analyse customer, transactional, repayment, and business health data to identify drivers of risk, loss, approval rates, and customer outcomes
• Identify trends, correlations, and anomalies that impact take up rate, credit performance and portfolio stability
• Support portfolio analytics: vintage analysis, roll-rates, migration, early warning indicators, collections funnel analytics, and loss driver deep-dives
• Collaborate with product, finance, and operations teams to embed data-driven decision-making

Credit Policy & Experimentation

• Design, run, and evaluate credit policy experiments (cut-offs, limits, pricing/risk trade-offs, segment strategies), including post-implementation reviews
• Develop segmentation and behavioural models to drive proactive portfolio management
• Support stress testing and scenario analysis

Innovation & Automation

• Design and deploy machine learning models for predictive credit risk assessment
• Leverage advanced analytics to streamline underwriting and risk monitoring processes
• Continuously explore new data sources and analytical methods to improve risk evaluation
• Work with Data/Engineering to improve data definitions, quality, lineage, and reproducible pipelines; document feature logic and assumptions

Governance & Documentation

• Contribute to governance documentation including model inputs, feature catalogues, monitoring evidence, and change logs.
• Ensure all modelling work meets internal standards and applicable regulatory requirements

Requirements

• Degree in Data Science, Statistics, Mathematics, or a related quantitative field
• 3+ years of experience in data science, credit analytics, or credit risk management within a bank, fintech, lender, or consulting environment

Essential

• Strong background in statistical modelling, machine learning, and predictive analytics
• Proficiency in Python and/or SQL
• Experience building and validating credit risk models, including scorecards and provisioning models
• Solid grounding in predictive model evaluation - ranking performance, calibration, and stability - and business impact measurement
• Exposure to advanced machine learning concepts (ensemble methods, cross-validation, hyperparameter tuning) and the ability to apply them responsibly in production settings
• Strong business acumen with the ability to communicate insights to both technical and non-technical stakeholders
• 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

Desirable

• Experience in SME lending, merchant cash advances, or alternative credit products
• Familiarity with IFRS 9, Basel, or equivalent credit risk regulatory frameworks
• Experience with bureau data, open banking/transactional data, device/behavioural signals, or alternative data sources
• Exposure to cloud-based data platforms (Databricks, BigQuery, Snowflake, AWS, GCP, or Azure) and version control (Git/Bitbucket)
• Familiarity with model monitoring, governance, and documentation practices in regulated environments
