You’ll work closely with Product, Engineering, Data Analytics, Operational and member Experience partners. The role is a good fit for someone who can move between portfolio-level questions and detailed case review, conduct ground level investigation and data queries , communicate what the evidence supports, and turn findings into better risk decisions and processes.

Investigate fraud and dispute cases (30%) - Review assigned cases from intake through resolution or escalation. Bring together relevant member statements, transaction and account history, merchant evidence where applicable, and risk signals. Assess evidence quality and consistency; document what is supported, what remains uncertain, and the recommended next step in accordance with established policies and decision authority. Understand agent SOPs and get familiar with using agent tools with the goal to improve AHT and decision accuracy.
Improve processes and automation (20%) - Identify and apply AI and automation opportunities across dispute and fraud workflows to reduce repetitive manual work, improve consistency, and accelerate analysis. Partner with relevant teams to test solutions, validate outputs, and ensure appropriate human review and controls before implementation.
Build reporting and monitor performance (10%) - Develop and maintain actionable dashboards and reports that track risk performance against loss and member-experience metrics.
Collaborate on ad hoc needs (15%) - Partner with internal stakeholders to answer time-sensitive questions and communicate findings clearly to technical and non-technical audiences.
