As a Staff Data Scientist, you’ll lead the design and execution of advanced analytics, statistical modeling, and
machine learning across Onsera’s platform, leveraging complex healthcare data—claims, clinical records, and
real-world evidence—to power population risk stratification, predictive modeling, and AI-driven decision
support. You’ll be a strong independent applied research operator capable of tackling greenfield projects
end-to-end while shaping the strategic direction of the data science function, defining modeling strategies
that balance immediate needs with long-term vision (2+ years ahead), setting ML/AI standards and tooling,
and elevating the work of others through rigorous technical review in close partnership with Product,
Engineering, and Clinical teams.
