Skills and Qualifications

• 4+ years of hands-on data science / applied ML in production environments
  
• Strong Python (pandas, scikit-learn, numpy) and SQL — you can go from raw data to deployed model without waiting on engineering
  
• Deep practical experience with classifier and regression modeling — feature engineering, model selection, calibration, evaluation under class imbalance
  
• Solid applied statistics: hypothesis testing, regression, experimental design, dealing with selection bias and censored outcomes
  
• Experience working with messy real-world financial data (transactional data, bank statements, payments, credit bureau data) — or strong evidence you can ramp on it quickly
  
• Comfort with relational databases (Postgres / MySQL) and modern data tools
  
• Strong written and verbal communication — you can explain a model's behaviour to a credit officer, a marketer, and an engineer in the same week
  

Credit & underwriting

• Build, deploy, and continuously improve credit scoring models using bank statement data, payment
  
• histories, CRB pulls, and in-app behavioural signals
  
• Design automated underwriting flows that serve both digitally acquired customers and salessourced applications
  
• Implement model retraining pipelines so scoring improves as we accumulate repayment outcomess - not as a quarterly project
  
• Own model performance monitoring, drift detection, and automated alerting
  
• Partner with Risk and Operations on policy thresholds, override rules, and the human-in-the-loop processes that wrap the models
  

Growth & marketing analytics

• Optimize ad targeting across our acquisition channels — audience selection, bid strategy, creative performance, lookalike construction
  
• Instrument and analyze the acquisition funnel end-to-end (impression → click → install → KYC → first loan → repayment)
  
• Design and run A/B tests on acquisition and product experiences; build the experimentation infrastructure so the team can run tests without you
  
• Build attribution and LTV/CAC models that the business can actually act on Cross-cutting
  
• Write clear technical specs that AI-assisted workflows can execute against
  
• Use AI tools (Claude Code, Codex, etc.) to move 10x faster on data wrangling, feature engineering, and analysis — while rigorously validating outputs
  
• Extend our data platform with new sources (third-party APIs, CRB providers, payment rails) when a model needs them
  
• Process, clean, and verify data integrity — especially for anything that touches lending decisions
  
• Present findings clearly to non-technical stakeholders; defend recommendations with data
