Accountabilities: Design, build, validate, and deploy scalable actuarial models, including IBNR, financial forecasting, risk adjustment, pricing, and other healthcare risk models, integrating them directly with platform APIs and engineering pipelines.

Apply actuarial expertise to complex healthcare data involving areas such as eligibility and claims, transforming real-world data and business challenges into reliable, production-ready solutions.

Collaborate with Product, Delivery, and Engineering teams to provide actuarial domain context for AI-enabled products, including refining prompts, developing evaluation frameworks, and creating high-quality question-and-answer datasets.

Help improve the fidelity and effectiveness of automated actuarial outputs by applying professional actuarial judgment and rigorous evaluation practices.

Embed actuarial governance, professional standards, validation methodologies, and quality controls into automated models, tools, and data pipelines.

Lead rapid proof-of-concept development to test complex actuarial logic, validate new algorithms, and de-risk technical approaches before broader engineering implementation.

Translate traditional actuarial methodologies into modern software and data science workflows, identifying opportunities to improve scalability, efficiency, and reproducibility.

Partner across Product, Engineering, Delivery, and other technical teams to provide technical leadership and communicate complex actuarial concepts clearly to diverse stakeholders.

Explore emerging technologies and methodologies, including generative AI, LLMs, distributed computing, and cloud data infrastructure, to solve actuarial and healthcare risk problems in innovative ways.

Requirements

ASA credential required, with FSA strongly preferred.

6+ years of healthcare actuarial experience working extensively with data, including eligibility and claims data, and developing actuarial models.
