Overview

You will design and build the v1 rule-weighted composite scoring logic that turns normalized risk signals into a transparent, defensible score. Working with Python, scikit-learn, and SQL, you will define feature groupings, weights, thresholds, and guardrails. You will partner with data engineering and application teams to productionize scoring logic and establish validation and monitoring approaches. This role offers the chance to shape the architecture for future interpretable ML models while preserving explainability for adjudicator-facing workflows.

What You'll Do8

  • 1Build and tune v1 rule-weighted composite scoring logic using normalized inputs from the common risk-signal schema.
  • 2Define scoring framework components including feature groupings, weights, thresholds, guardrails, and handling of missing or partial data.
  • 3Create interpretable explanations for scores and drivers suitable for adjudicator review, including reason codes and key contributing signals.
  • 4Design the scoring architecture to support evolution from rules and weights to interpretable ML models while maintaining auditability.
  • 5Prototype and evaluate interpretable model classes and explanation methods such as SHAP-based explanations, constrained or monotonic models, and rule-based hybrids.
  • 6Partner with data engineering and application teams to productionize scoring logic, covering data inputs, contracts, output formats, and performance expectations.
  • 7Establish validation and monitoring approaches including basic model or score QA, drift indicators, and score distribution checks.
  • 8Document scoring methodology, assumptions, and limitations for stakeholder understanding and accreditation or compliance artifacts.

Requirements8

  • 1Maintain an active TS/SCI security clearance.
  • 2Bachelor's Degree and 8 to 10 years of experience; Master's Degree and 6 to 8 years; PhD and 3 to 5 years (in lieu of Bachelor's, 6 additional years of relevant experience).
  • 33-5 years of applied data science experience delivering scoring, ranking, or decision-support models.
  • 4Experience implementing interpretable approaches such as rule-based systems, transparent composite scores, or explainability methods including SHAP.
  • 5Strong Python skills including scikit-learn and common data science workflows.
  • 6Hands-on experience with SQL for data analysis, feature development, and validation.
  • 7Ability to communicate scoring logic clearly to technical and non-technical stakeholders, including explaining tradeoffs between accuracy and interpretability.
  • 8Familiarity with adjudicative, compliance, fraud, or risk-scoring domains (preferred or bonus).
