Solution Architect - CREST New Technology - EUI Transformation

Division: Group Business Solutions

IT is at the heart of Euroclear’s business, driving continuous innovation and delivering cost-efficient, high-quality services to our customers. Today, our core business runs on HP NonStop Servers (Tandem), with communications infrastructure and message routing implemented on Red Hat Enterprise Linux.

Euroclear is embarking on a major transformation: migrating CREST from COBOL programs on the HPE NonStop Guardian platform to a modern, commoditised environment such as Linux. The new technology stack will be Java-based, leveraging Event Hub technologies (e.g., Kafka) for integration between migrated services and legacy systems. Migrated services must be platform-independent, capable of running on OpenShift Linux environments. This migration will be incremental and span several years.
