Senior Enterprise Architecture Consultant – Enterprise Modernization

Position Description

The Senior Enterprise Architecture Consultant owns and governs the end to end target state architecture for a large scale enterprise modernization and legacy transition program. The role translates business strategy into solution architecture and facilitates collaboration across the corporate ecosystem to deliver business outcomes.

The role leads solution architecture, design, and analysis across digital services, application development, data, integration, cloud, security, DevOps, and operations. The role defines architectural patterns and roadmaps that support modern applications and services, and the transition of legacy capabilities while maintaining continuity of business operations.

The Senior Enterprise Architecture Consultant provides technical leadership to senior engineers and stream architects, balancing near term delivery needs with long term architectural integrity. The role ensures solutions are scalable, performant, secure, compliant, and reusable. The architectural patterns, service designs, standards, and governance models established for this flagship program are intended to become foundational assets for future transformation initiatives.
