Since 1889, we have aligned our efforts with our three guiding Principles That Endure: Service, Expertise, and Integrity.

The individual in this role is expected to stay abreast of industry trends, vendor offerings, technology innovation, and changing customer requirements to provide effective solutions aligned to business outcomes.

The Network Architect will translate logical or conceptual designs into physical designs, accounting for requirements, target environments, processes, performance needs, existing systems and services, and non-functional requirements such as capacity, availability, and performance. These designs should align with modernization and transformation roadmaps and initiatives to move the enterprise in the right direction. The Network Architect provides technical design guidance and strategic leadership to engineering and application teams and acts as the ultimate escalation point for network issues. The Network Architect also serves as the technical escalation point of contact for infrastructure teams, application development teams, and leadership.

This role will provide trouble resolution of the global network for escalated issues and may perform on-call duties and off-hours support when needed.
