evaluate technologies and architectures (e.g., new connectivity models, modern security access services)

be accountable for architectural outcomes and actively support successful execution through close collaboration with service providers and key stakeholders

translate business, security, and operational requirements into robust, scalable, and secure network architectures

review, provide architectural input on, and guide service provider designs to ensure alignment with enterprise architecture and risk tolerance

experience producing, reviewing, and validating architecture artefacts such as reference architectures, solution designs, and integration patterns

familiarity with industry standards, performance management practices, change management processes, and service delivery models

Analytical and strategic thinking

able to design architecture solutions for complex, long-term initiatives

skilled at solving integration challenges and navigating unclear or evolving requirements

able to research, evaluate, and recommend innovative architecture strategies

comfortable developing performance measures and adapting to new technologies
