Advertisement



Job Description

If you’re tired of the same old banking models and want to use your expertise to build solutions that actually shape how credit decisions are made (especially in data-scarce, high-impact markets like SME lending) – this is your chance to make it happen.
You’ll be joining a forward-thinking team that values curiosity, bold ideas, and technical excellence. Here, your insights will actually influence business strategy, not just sit in a report.

Key Responsibilities:

  • Design, develop, and review application scorecards, including reject inference and validation methodologies.
  • Lead feature engineering efforts to boost model accuracy and business relevance.
  • Collaborate with stakeholders to align scoring strategies with commercial goals.
  • Develop predictive solutions in low-data environments, especially for SME lending.
  • Provide mentorship and guidance to junior analysts and data scientists.
  • Present technical concepts to senior stakeholders with confidence and clarity.
  • Drive thought leadership in credit risk modelling and best practices.
  • Manage multiple projects simultaneously and deliver on key business priorities.

Job Experience and Skills Required:

  • BSc/BCom in Mathematics, Statistics, or Engineering (or related quantitative field).
  • Minimum 8 years’ hands-on experience in application scoring and credit risk modelling.
  • Strong proficiency in SAS (non-negotiable); experience with Paragon Modeler is advantageous.
  • Proven record in scorecard development, reject inference, model validation, and feature engineering.
  • Experience across multiple industries (banking, fintech, telecoms, insurance, retail, etc.) will be highly regarded.
  • Exceptional communication skills, strategic mindset, and ability to influence senior stakeholders.
  • Experience with SME lending, alternative credit scoring, or ML-driven scoring solutions.
