• Provide architecture-level guidance on highly complex or escalated network issues, ensuring root causes are understood and durable remediation strategies are implemented.

RFP, Vendor & Partner Leadership

• Lead or significantly influence complex RFPs, technology evaluations, and supplier selections.
• Define technical requirements, evaluation criteria, and architectural principles used to assess proposed solutions.
• Critically evaluate vendor architectures and recommendations, challenge assumptions where appropriate, and ensure proposed solutions align with enterprise requirements.
• Establish and maintain strong technical relationships with strategic technology vendors and service providers.

Cross-Functional Leadership

• Partner with engineering, operations, cybersecurity, infrastructure, application, and business teams to develop and execute enterprise network solutions.
• Communicate complex technical concepts and architectural trade-offs with clarity and credibility to both technical and non-technical stakeholders.
• Build consensus across diverse stakeholders while maintaining architectural integrity and technical standards.
• Provide technical leadership and mentorship to engineers and other architects.
