Dunnes Stores Tech Stack

Irish retail chain modernizing legacy systems with cloud and data platforms

Dunnes Stores operates a legacy retail technology stack built on AS/400, Oracle EBS, and Forms — but is actively modernizing toward Azure, .NET, and cloud-native data infrastructure (Azure Synapse, Data Factory, Fabric). The hiring acceleration skews heavily toward senior and lead roles in data and engineering, signaling investment in building internal technical capability rather than outsourcing the transformation. Current pain points (shadow systems, compliance gaps, supply-chain digitization) and projects (Dublin engineering hub, cybersecurity strategy, ecommerce roadmap) reveal a multi-front modernization effort.
