Knowtion Health is seeking a Senior AI Data Scientist who owns systems end to end - framing the problem, building and validating the models, and standing up the data pipelines and monitoring that keep them running in production. The role is data science and engineering in equal measure: the statistical rigor to build a model that is sound, and the engineering craft to ship and operate it. Because our models touch payments and patients, they are held to a high bar: statistically defensible, operationally reliable, and defensible to an auditor. This is a senior individual-contributor role for someone who has both built models and kept them alive in production.
The Opportunity:- Frame ambiguous revenue-cycle problems as tractable modeling problems and own them end to end - such as claim and invoice viability scoring, denial and underpayment prediction, revenue/ARR prediction, and work prioritization - from hypothesis to a validated, monitored result in production.
- Build and validate models with statistical rigor: thoughtful feature design, sound handling of missingness and class imbalance, calibration, honest evaluation against simple baselines, and a clear treatment of uncertainty.
- Design, build, and maintain the data pipelines feeding these models - integrating with source collections, billing, and EHR systems and internal data stores, and handling data collection, cleansing, field mapping, and payer/plan normalization - with a bias toward reliability and data quality.
- Establish and own MLOps practice: model monitoring and drift detection (e.g., population stability), calibration and threshold selection, benchmarking against simple baselines, explainability (e.g., SHAP and interpretable coefficients), experiment and version tracking, and model documentation such as model cards.
- Partner with subject-matter experts to encode business-rule and heuristic logic alongside statistical models where that produces a more accurate or more defensible result.
- Gather and document business requirements for revenue-cycle initiatives, including workflows, decision points, stakeholder objectives, operational constraints, success criteria, data availability, and underlying business assumptions, and maintain traceability as those requirements evolve.
What you bring:- Several years building and validating models and operating them in production, with clear ownership of at least one model that a product or business function depended on.
- A degree in a quantitative field such as statistics, computer science, mathematics, or data science, or equivalent demonstrated ability.
- A strong statistical foundation - experimental design, inference, evaluation of imbalanced real-world data, and knowing when a result is real versus an artifact of how it was measured.
- Deep, genuine fluency in the fundamentals: train/test discipline, overfitting and regularization, data leakage, class imbalance, calibration, and how to evaluate a model honestly. These will be probed directly in the interview.
- Strong production Python (pandas, NumPy, scikit-learn; deep-learning frameworks a plus) and strong SQL, including stored procedures and performance-aware queries against large tables, with comfort using Git and reproducible workflows.
- Hands-on MLOps: monitoring, drift, experiment tracking, versioning, and what it takes to keep a model healthy in production.
- Comfort owning the data pipeline, not just the model - source-system integration, scheduling, and data-quality controls.
