Description

  • Own end-to-end predictive underwriting and pricing workstreams from problem framing and feature engineering through deployment, monitoring, retraining, and impact measurement.
  • Define analytics-ready datasets, data-quality standards, and reusable features across claims, pharmacy, utilization, financial, underwriting, and external data.
  • Apply point-in-time development and out-of-time validation to address claims maturity, seasonality, leakage, stability, and uncertainty.
  • Develop, compare, and challenge predictive models, statistical distributions, and hybrid rule/model approaches.
  • Evaluate emerging methods, including deep learning and GenAI, when they can improve accuracy, scalability, decision quality, or efficiency.
  • Translate model requirements into features, collaborate with business and Legal teams, and manage third-party evaluations and ROI analyses when needed.
  • Produce explainable, reproducible model outputs while following documentation, testing, monitoring, retraining, rollback, responsible-AI, privacy, and governance standards.
  • Build reusable data science components, pipelines, evaluation patterns, and scoring capabilities across Pareto Predict.
  • Translate model outputs into underwriting decision support and recommend whether solutions should scale, iterate, or stop based on measured results.
  • Provide technical reviews, mentoring, reusable components, and improvements to shared data science practices.

Requirements

  • Bachelor’s or master’s degree in Statistics, Data Science, Computer Science, Mathematics, Engineering, or a related quantitative field; advanced degree preferred.
  • 8+ years of experience in data science, machine learning, statistics, or actuarial analytics, including substantial healthcare, pharmacy, insurance-risk, or sensitive longitudinal data experience.
  • Proven ability to independently own models or analytical workstreams from development through production.
  • Advanced Python and SQL, with experience in scikit-learn, XGBoost, GBMs, or comparable frameworks.
  • Expertise in supervised and unsupervised machine learning, explainability, statistical distributions, rare-event and high-cost modeling, calibration, and optimization.
  • Production model and MLOps lifecycle experience on AWS or a comparable cloud platform, including Git, testing, deployment, monitoring, retraining, rollback, documentation, and governance.
  • PySpark or comparable distributed-computing experience preferred; PyTorch experience is a plus.
  • Kedro or similar pipeline framework experience preferred; familiarity with LLMs, prompt engineering, RAG, embeddings, vector databases, or agentic frameworks is helpful.
  • Strong business judgment and communication skills, with the ability to connect analytical work to measurable outcomes and influence cross-functional decisions.
  • Must be authorized to work in the United States without employment visa sponsorship now or in the future.

Benefits

  • Fully paid medical, dental, and vision benefits.
  • Flexible PTO.
  • 401(k) company contribution.
