Data Scientist, Principal (Hartford)

Your Role

The AI & Machine Learning team works in partnership across the enterprise to accelerate business outcomes by applying AI, machine learning, and generative AI to build intelligent products that create intelligence at scale. Reporting to the Director, AI & Machine Learning, the Data Scientist, Principal will lead the development and deployment of novel applications that leverage generative AI models. This role focuses on rapidly developing new features and working across partner teams to deliver solutions and maximize impact, translating cutting‑edge AI research into real‑world products and taking features from 0 to 1. You will design, build, and ship production‑grade AI products including LLM‑powered applications, AI agents and copilots, retrieval‑augmented generation (RAG) and search, and AI‑enabled automation embedded directly into customer‑facing applications and enterprise workflows such as claims, payment integrity, clinical insights, and member experience. You will set the technical direction for how AI is applied across the organization.

Our leadership model is about developing great leaders at all levels and creating opportunities for our people to grow – personally, professionally, and financially.

Hybrid

This role requires employees to be in-office based on our hybrid workplace model, balancing purposeful in‑person collaboration with flexibility. For most teams, this means coming into the office two days each week.

Employees living more than 50 miles from an office location will work with their manager to determine in‑office time based on business need.
