Develop, validate, and deploy predictive and causal models and AI tools into Arine's medication management platform, with careful attention to bias, confounding, and generalizability
Partner with clinicians and HEOR researchers to frame questions as well-defined causal estimands and translate findings into clinical and operational decisions
Create presentations and reports communicating methods, assumptions, and results to the Data Science team and cross-functional stakeholders
Participate in critical reviews within the Data Science team on everything from methods and study design to implementation strategy and code

Qualifications:

Master's or PhD in Statistics, Biostatistics, Epidemiology, Health Economics, Computer Science, a quantitative/physical science, or a related field
Strong foundation in statistical inference and study design, and demonstrated expertise in causal modeling with observational data, e.g., propensity score methods, inverse probability weighting, instrumental variables, difference-in-differences, regression discontinuity, marginal structural models, and target trial emulation
Demonstrated, hands-on experience with causal machine learning methods, e.g., double/debiased machine learning, causal forests, targeted maximum likelihood estimation (TMLE), or meta-learners (T-/X-/R-learners)and familiarity with libraries such as WeightIt, MatchIt, grf, DoWhy, EconML, or CausalML
Meaningful experience (3+ years) working with real-world healthcare data (e.g., medical and pharmacy claims or EHR data) and analyzing patient outcomes
Experience handling the practical challenges of real-world data: missingness, confounding, selection bias, and measurement error
Proficiency with R, Python (scikit-learn, pandas, numpy), and SQL
Experience working cross-functionally to define analysis objectives and deliver analytical results
Demonstrated ability to work independently, exercise good judgment, prioritize multiple projects, and problem-solve under tight deadlines and resource constraints
Excellent written, interpersonal, and presentation skills, including the ability to convey complex technical concepts clearly to audiences with varying levels of technical understanding

Bonus:

Experience modeling cost-of-care outcomes (e.g., total cost of care, utilization, avoidable spend) in high-risk, high-cost populations
Deep experience with advanced difference-in-differences methods and related quasi-experimental designs (e.g., staggered/event-study DiD, synthetic control)
Productive use of AI-enhanced coding tools (e.g., Claude Code) in day-to-day development
Familiarity with survival analysis and longitudinal/repeated-measures methods
Experience deploying models into commercial software products
