Oscar Health is a publicly traded health insurance company building internal AI/ML infrastructure and risk-adjustment automation. The tech stack (Python, Go, Vertex AI, BigQuery, Salesforce) paired with active adoption of RAG signals a shift toward AI-assisted underwriting and claims processing. Hiring is accelerating across operations, healthcare, and data teams while engineering remains lean (30 roles) — consistent with a company scaling backend analytics and compliance automation rather than pure product engineering.
