Monitor network health, performance, and capacity using advanced tools; create dashboards and alerts.

Security & Compliance

Drive network security initiatives, including design and implementation of intrusion prevention systems (IPS), NAC, and Zero Trust architecture.

Ensure compliance with internal and external security standards through network hardening, audits, and regular reviews.

Design and maintain secure remote access and multi-site connectivity strategies.

Perform security assessments and vulnerability mitigation related to network layers.

Troubleshooting & Support

Act as the highest escalation point (Tier 3/4) for complex network issues, including packet capture, traffic analysis, and protocol debugging.

Lead root cause analysis (RCA) efforts for critical incidents, post-mortems, and corrective/preventive actions.

Work closely with vendors to resolve hardware/software bugs and proactively manage lifecycle support contracts.

Documentation & Reporting

Maintain detailed documentation of network infrastructure, including diagrams, IP schemas, configuration repositories, and SOPs.

Generate performance and availability reports; present findings and recommendations to both technical and business stakeholders.

Leadership & Collaboration

Collaborate with enterprise architects, cybersecurity teams, DevOps, and application owners to align network infrastructure with business goals.

Interface with customers and leadership on solution designs, RFPs, PoCs, and implementation roadmaps.

Mentor junior and mid-level engineers; lead knowledge-sharing initiatives and develop playbooks for best practices.

Required Skills & Qualifications:

Minimum 10+ years of experience in enterprise networking with strong architecture and troubleshooting background.

Proven expertise in multi-vendor environments: Cisco, HP, Aruba, Juniper, Avaya.

Advanced knowledge of routing protocols (BGP, OSPF, EIGRP, etc.) and switching technologies (VLANs, STP, VTP, port-channeling).

Strong experience with firewalls and network security appliances (Cisco ASA, Palo Alto, FMC, Juniper FTD, etc.).

Deep understanding of high availability, load balancing, VPNs, cloud networking (AWS/Azure/GCP), and SD-WAN.
