D&T Manager - Infrastructure Domain Architect

Purpose of the Job

The Infrastructure Domain Architect is responsible for defining, governing, and continuously evolving the organization’s Infrastructure Architecture Domain, ensuring that infrastructure solutions across on‑premises, cloud, network, identity, and security domains are secure, scalable, resilient, cost‑effective, and aligned with Enterprise Architecture direction and business objectives.

Acting as the architectural authority for infrastructure within the infrastructure organization, this role translates enterprise‑level architecture principles and strategies into practical, implementable reference architectures, standards, and design patterns. The Infrastructure Domain Architect ensures architectural consistency, quality, and compliance across infrastructure initiatives, while reducing technical debt, risk, and fragmentation.

The role works in close partnership with Enterprise Architecture, Security, Application Architecture, and Delivery teams to support strategic initiatives such as cloud adoption, modernization, resilience, and platform standardization, while enabling reliable and efficient day‑to‑day infrastructure operations.
