We are supporting a public sector client in hiring a Data Architect with strong expertise in Entity Resolution and Master Data Management. The role will focus on designing and implementing scalable, secure and high-quality data architectures that enable accurate data matching, deduplication and linkage of complex datasets to support decision-making and analytics across the organisation.
This is a senior, hands-on architecture role requiring someone who can operate at both the strategic and technical level, for defining data models, establishing governance rules and leading the implementation of entity resolution solutions across large, complex and multi-source data environments.
