As a member of the Rebate Analytics team, you will play a key role in growing and enhancing our Rebates Estimation Platform - a cutting-edge model capable of real-time, complex calculations to predict financial outcomes for clients, such as rebate payment estimates and reimbursements at the individual claim level. By streamlining complex contract rules and payment schedules, it significantly reduces the time it takes to process and deliver financial insights, helping clients make better decisions and manage their cash flow more effectively. This role has a huge impact as the model serves as source of truth for rebate estimates across the entire PBM business. The model also acts as the foundational data provider for seven downstream platforms that are essential to multiple stakeholder teams and clients.
Careers with Optum offer flexible work arrangements and individuals who live and work in the Republic of Ireland will have the opportunity to split their monthly work hours between our Dublin or Letterkenny office and telecommuting from a home-based office in a hybrid work model.

• Improve the accuracy, efficiency, and reliability of the model
• Add new capabilities to the model to meet evolving business and client needs
