What You'll Do

• Lead the architecture, design, and implementation of complex Cisco-based networks that are scalable, secure, resilient, and compliant with industry best practices and organizational standards.
• Act as a senior technical escalation point for complex incidents; drive root cause analysis, corrective actions, and long-term improvements to prevent recurrence.
• Define, implement, and continuously improve proactive monitoring, alerting, and observability (coverage, thresholds, event correlation, and response runbooks) to detect and resolve issues quickly.
• Own and maintain network architecture artifacts including network diagrams, standards, configuration baselines, and security documentation; ensure documentation is current and audit-ready.
• Lead network lifecycle management, including patching, upgrades, and replacement planning; develop implementation plans that minimize risk and business impact.
• Design and support multi-cloud and hybrid connectivity patterns (private/public/hybrid), partnering with cloud and security teams to ensure consistent standards and secure integration.
• Implement, operate, and optimize network services including firewalls, VPNs, IDS/IPS, SDA, Viptela SD-WAN, VLANs, and load balancers; ensure high availability and secure configurations.
• Develop and enforce network standards and operational practices, including change management, configuration management, and automation where appropriate.
• Provide technical guidance and mentorship to other team members; review designs/changes for quality, security, and alignment to standards.
• Evaluate emerging network and cloud technologies; create recommendations and lead adoption efforts that improve performance, reliability, security, and operational efficiency.

What You'll Bring

• Bachelor's degree in Computer Science, Information Technology, or related field (or equivalent combination of education and experience).
• Minimum of 7–10 years of progressive IT experience, including 5+ years in network engineering/administration supporting enterprise environments.
• Demonstrated experience designing and operating complex, highly available LAN/WAN and data center networks in a regulated or high-availability setting.
• Strong practical experience with Cisco enterprise networking (routing/switching, SDA, Viptela SD-WAN) including architecture decisions, configuration standards, and operational support.
• Strong understanding of networking protocols and technologies, including TCP/IP, BGP, OSPF, QoS, VOIP, VLANs, MPLS, SD-WAN, and load balancing.
• Hands-on experience with network security concepts and technologies, including firewalls, VPNs, IDS/IPS, segmentation, and secure remote access.
• Proven experience with multi-cloud and hybrid connectivity (AWS, Azure, and/or Google Cloud), including network design patterns, connectivity options, routing, security controls, and operational troubleshooting.
• Experience establishing and improving monitoring/alerting and observability practices (coverage, tuning, and actionable alerting). Familiarity with LogicMonitor or similar monitoring platforms preferred.
• Ability to lead technical work end-to-end: requirements intake, design, change planning, implementation, validation, documentation, and operational handoff.
• Strong troubleshooting skills with a structured approach to incident response and root cause analysis, including documenting corrective/preventative actions.
• Strong communication skills; able to influence standards and partner effectively across infrastructure, cloud, security, and application teams.
• Flexibility to travel up to 15%, as needed.

Nice to Have

• ITIL v3 or v4 Foundation certification (or higher).
