The Opportunity

Escalating litigation costs are putting immense pressure on insurance companies to manage expenses effectively. Traditional methods are often time-consuming and lack the analytical depth required to uncover hidden patterns and anomalies in legal expenditures. Milliman Datalytics-Defense® offers a cutting-edge, AI-driven legal spend management solution designed to transform how insurance companies handle legal e-billing. Our platform goes beyond basic invoice review, providing comprehensive analytics to optimize legal spend and claim outcomes.

Our Data Science team relies upon a suite of modeling tools that ranges from Azure ML Studio, including XGboost for GLMs and machine learning to Azure OpenAI ChatGPT fine-tuned models. Data Science Interns support the design and development of high-quality modeling solutions through data processing, analytics, building dashboards and reports, testing the integrity of the fine-tuned model, documentation and other projects. This is a great opportunity for a naturally curious, thoughtful student to apply quantitative techniques in real-world business problem-solving.

Responsibilities include:

• Gather, clean, and validate structured data derived from the fine-tuned model
