Erste Digital Tech Stack

Digital banking infrastructure for Erste Group's 16M+ customers across Central Europe

IT Services and IT Consulting Wien, Wien 1,001–5,000 employees Privately Held

Erste Digital operates as the engineering backbone of Erste Group, a regional banking institution serving over 16 million customers across Central Europe. The tech stack—Python, Go, Kubernetes, AWS/Azure/GCP, plus legacy DB2 and Adabas—reflects a dual-layer operation: modern cloud-native services layered over maintained mainframe systems. Active projects prioritize mainframe-to-cloud integration and workflow modernization (adopting Pega), while pain points cluster around legacy infrastructure constraints and developer velocity, suggesting the organization is mid-transformation from datacenter-dependent operations toward distributed cloud architecture.
