About the role

Key responsibilities & impact

Serve as the final technical authority during critical incidents where standard escalations have proven ineffective.
Lead deep-dive forensic analyses to identify root cause and provide immediate workarounds or permanent fixes.
Utilize advanced debugging and packet analysis to isolate complex network anomalies.
Provide real-time technical intervention to restore service availability during major outages.
Conduct independent, peer-level reviews of proposed architectural changes, capacity upgrades, and new site deployments.
Identify hidden risks, single points of failure, and configuration vulnerabilities in proposed network designs.
Provide a "Red Team" perspective on network changes to ensure they meet the highest standards of stability and performance.
Validate complex route redistribution strategies, BGP policy implementations, and high-availability designs prior to production deployment.
Provide expert guidance on lifecycle management, technology roadmaps, and hardware/software selections.
Assist in the technical evaluation of new Cisco platforms (e.g., Catalyst 9000 series, Nexus 9k) to ensure compatibility and optimal configuration.
Advise leadership on high-risk technical decisions, translating complex network issues into clear business impact assessments.
Contribute to the development of network standards, best practices, and operational runbooks.
Guide internal engineering teams through complex resolution processes to facilitate knowledge transfer during engagements.
Conduct post-incident reviews and provide detailed root-cause analysis reports.
Recommend proactive measures and architectural improvements to prevent recurrence of critical incidents.

Requirements

What you’ll need

Active CCIE Certification (Enterprise Infrastructure or Routing & Switching) is mandatory.
Minimum of 10+ years of experience supporting large-scale, mission-critical, and global Cisco environments.
Demonstrable experience supporting mission-critical Cisco environments with thousands of users and multiple data centers.
Proven track record of successfully resolving complex, multi-vendor network incidents at the highest technical level.
Expert-level command of OSPF (multi-area, LSA types, summarization) and EIGRP.
Advanced BGP configuration, policy-based routing, route filtering, AS-Path manipulation, and complex route redistribution strategies.
Deep understanding of MPLS L3VPNs, L2VPNs, and/or Segment Routing (SR-MPLS) is highly desirable.
Advanced design and troubleshooting of VSS (Virtual Switching System) and StackWise Virtual.
Expert knowledge of stateful failover mechanisms, NSF (Non-Stop Forwarding), and graceful restart.
In-depth knowledge of campus and data center switching architectures, spanning-tree optimization, VLAN design, and QoS implementations.
Familiarity with VXLAN, EVPN, and Cisco ACI is considered a strong asset.
Demonstrated ability to function clearly and effectively during high-stakes, high-pressure outages.
Ability to explain complex technical issues to non-technical executives (CTO, CIO) in clear business terms.
Must be able to respond to selective engagement requests with urgency (specific SLA for response to activation required).
Ability to operate autonomously, providing unbiased, peer-level analysis without reliance on vendor scripts.
