Sr Network Engineer

The Senior Network Engineer provides technical leadership and deep hands‑on expertise in Cisco and multi‑cloud networking to design, implement, operate, and continuously improve the organization’s network infrastructure. This role leads complex initiatives across LAN/WAN/SD-WAN, cloud connectivity, and network security, ensuring scalable, secure, and highly available services. The Senior Network Engineer owns key aspects of network architecture, standards, monitoring strategy, capacity planning, and lifecycle management, and serves as a subject‑matter expert (SME) partnering with infrastructure, security, and application teams to enable reliable hybrid and multi‑cloud integrations.

• 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.

• 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 Logic Monitor 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…
