Senior Analytics Engineer

Hi, we're Oscar. We're hiring a Senior Analytics Engineer to join our Data Team.

Oscar is the first health insurance company built around a full stack technology platform and a relentless focus on serving our members. We started Oscar in 2012 to create the kind of health insurance company we would want for ourselves—one that behaves like a doctor in the family.

About the role:

The Senior Analytics Engineer designs, builds, and maintains conformed dimensional models that convert raw operational data from multiple independent source systems into reliable, well-structured analytical assets spanning multiple business domains. The Senior Analytics Engineer partners with domain experts and stakeholders to capture business logic, resolves cross-source inconsistencies, and translates requirements into Oscar’s unified dimensional model.

The Senior Analytics Engineer contributes to shared conventions and standards, mentors more junior team members, uses AI to accelerate development, and operates with high independence on complex modeling work

You will report into the Associate Director, Data Science.

Work Location:

This position is based in our New York City office, requiring a hybrid work schedule with 3 days of in-office work per week. Thursdays are a required in-office day for team meetings and events, while your other two office days are flexible to suit your schedule. #LI-Hybrid
