Banking Molesworth Street , Dublin 2 10,001+ employees Public Company

AIB operates a large, regulated financial institution built on a mature enterprise stack: SAP, Teradata, Oracle, IBM mainframe, and Ab Initio for core banking and risk infrastructure, with modern layers (Python, R, Kafka, Databricks) added for analytics and real-time processing. The hiring mix—weighted toward finance, risk, and data roles with accelerating velocity—reflects a bank actively building internal capability around RAROC modeling, market risk quantification, and liquidity prediction rather than outsourcing these functions.
