3. Gap Analysis & Modernization * Analyze current-state network gaps, technical debt, lifecycle risk, single points of failure, and performance bottlenecks. * Provide recommendations for modernization, standardization, and optimization, including cost/performance tradeoffs.

4. Cross-Domain Coordination * Coordinate with cloud/platform, cybersecurity, identity, endpoint/mobility, applications, data, and ITSM teams, as well as external carriers and providers. * Resolve complex cross-domain design conflicts under fixed milestones.

5. Documentation & Operational Handoff * Maintain standards, reference patterns, technical decisions, configurations, risks, and dependencies in approved repositories. * Support implementation, testing, migration, and stabilization, and troubleshoot complex cross-domain problems, communicating root cause, options, and corrective actions.

• Strong fundamentals in TCP/IP, routing, switching, segmentation, DNS/DHCP/IPAM, load balancing, resiliency, performance, monitoring, and security.
• Demonstrated experience producing technical network designs and supporting implementation, testing, troubleshooting, and operational transition.
• Ability to work across cloud and on-premises boundaries and through formal security/architecture review processes.
• Strong documentation and communication skills, with experience presenting designs and tradeoffs to both engineers and leadership.
• U.S. Citizenship Required.
