Job Purpose

The Network Senior Specialist within the IT Infrastructure & Operations department is responsible for designing, deploying, managing, and optimizing enterprise-wide network infrastructure and security solutions. Serving as the primary technical authority for high-availability networking, this role ensures seamless connectivity, robust data center operations, multi-cloud networking, and stringent cybersecurity controls across all corporate sites, data centers, and connected destinations.

Key Responsibilities

1. Network Architecture & Operational Delivery

• Design, configure, and maintain high-availability enterprise networks (LAN, WAN, WLAN, and Data Center topologies) aligned with departmental infrastructure baselines.
• Implement and manage advanced routing protocols (BGP, OSPF, EIGRP) and network virtualization technologies (VXLAN, EVPN, MPLS).
• Support multi-cloud network connectivity and hybrid setups (AWS DirectConnect, Azure ExpressRoute) to integrate corporate cloud environments with on-premise infrastructure.
• Oversee Software-Defined Networking (SDN / SD-WAN) deployments, site-to-site connectivity, and internet edge optimizations.

2. Infrastructure Maintenance & Incident Management

• Ensure 99.99%+ uptime across core infrastructure through proactive monitoring, continuous health checks, and redundant architectures.
• Function as the highest internal technical escalation point (Tier 3/4) for complex network outages, routing bottlenecks, and connectivity disruptions.
• Drive network lifecycle operations, including firmware updates, security patching, hardware lifecycle refresh, and automated configuration backups.
• Conduct deep-packet inspection and performance analysis using operational monitoring tools (Wireshark, SolarWinds, PRTG, NetFlow, Datadog).

3. Network Security & Operational Compliance

• Partner with the IT Security team to design and enforce network micro-segmentation, Next-Generation Firewalls (Palo Alto, Fortinet, Cisco Firepower), and Intrusion Prevention Systems (IPS/IDS).
• Manage enterprise Network Access Control (NAC / Cisco ISE / Aruba ClearPass), Zero Trust Network Access (ZTNA), and secure remote access/VPN infrastructure.
• Maintain compliance with enterprise IT security standards, audit requirements, and ITIL-aligned service management practices.

4. Automation & Service Improvement

• Automate recurring operational tasks, provisioning workflows, and configuration auditing using Python, Ansible, Terraform, or REST APIs.
• Maintain complete network topology documentation, IP Address Management (IPAM) records, standard operating procedures (SOPs), and operational runbooks.

5. Leadership & Vendor Coordination

• Lead infrastructure expansion and network modernization projects from design to operational handover.
• Provide technical mentorship to network engineers and system administrators within the IT Infrastructure & Operations team.
• Manage relations with telecom providers, ISPs, and hardware vendors to enforce Service Level Agreements (SLAs), manage link deliveries, and resolve escalated carrier issues.

Key Performance Indicators (KPIs)

• Infrastructure Availability & SLA: Core network uptime score across data centers and corporate sites.
• Mean Time to Repair (MTTR): Resolution speed for major (Tier 3) network incidents and outages.
• Operational Security & Hygiene: Zero critical unpatched network vulnerabilities or unapproved configuration changes.
• Project Delivery Execution: On-time execution of infrastructure rollouts, upgrades, and site integrations.

Qualifications & Experience

Education

• Bachelor’s degree in Computer Science, Computer Engineering, Information Technology, or a related technical discipline.

Work Experience

• 7-10+ years of hands-on experience in enterprise network engineering, data center networking, and infrastructure operations.
• Demonstrated history of supporting multi-site enterprise environments, campus networks, and cloud hybrid setups.

Professional Certifications (High-level required)

• Cisco: CCNP Enterprise / CCNP Security (CCIE is a strong plus)
• Firewall / Security: PCNSE (Palo Alto) or NSE 4/7 (Fortinet)
• Cloud Networking: AWS Certified Advanced Networking - Specialty or Azure Network Engineer Associate
• IT Service Management: ITIL v3/v4 Foundation (Preferred for operations alignment)
