Banking Evansville, IN 1,001–5,000 employees Public Company

Old National is a 1,000+ person regional bank with dual headquarters in Chicago and Evansville, operating across retail, commercial, and wealth management. The stack reveals a hybrid legacy-to-cloud transition: AS/400 and SAS anchor core operations while AWS and Microsoft 365 are actively expanding, paired with modern data tools (Python, Informatica, Power BI, Alterica) suggesting an ongoing data modernization push. Finance-heavy hiring (405 roles) paired with active projects around wealth adoption, risk frameworks, and data warehouse construction indicate a push to build competitive advantages in client relationships and operational resilience rather than wholesale platform replacement.
