• Architect, plan, and deploy highly available, scalable, and secure WAN, LAN, and Data center networks using Juniper (e.g., MX Routers, EX/QFX Switches) and Palo Alto Networks firewalls
• Develop and maintain the MPLS core network architecture, including L2/L3 VPNs, Traffic Engineering (TE), and Label Distribution Protocol (LDP)/Resource Reservation Protocol (ESVP)
• Design and implement complex BGP routing policies for multi-homed internet connectivity, inter-AS communication, and global route optimization
• Lead the network aspects of strategic projects, ensuring solutions align with business objectives, security standards, and best practices
• Design, implement, and fine-tune Quality of Service (QoS) policies (e.g., queuing, policing, shaping, classification) across the network to guarantee optimal performance for critical services
• Ensure reliable delivery and transport of VoIP services, including configuration and management of related infrastructure (e.g., Session Border Controllers, gateways) and their seamless integration
• Architect, plan, and support the network infrastructure specifically for IP Video Surveillance (IPVS) systems, including camera-to-VMS communication and storage networking
• Conduct network capacity planning and traffic analysis to accurately forecast bandwidth requirements for high-resolution, continuous recording IP cameras (e.g., H.264/H.265 streams)
• Design and manage the secure VLAN segmentation and network zoning strategy for all IPVS infrastructure, including ensuring proper PoE/PoE+ power budgets on supporting switches
• Configure and manage all features on Juniper SRX Series Firewalls and Palo Alto Networks Next-Generation Firewalls (NGFWs), including Security Policies, NAT, VPNs, User-ID, and Application-ID
• Enforce robust network security policies for all segmented networks, including implementing 802.1x authentication for cameras and other endpoint access where required
• Provide Tier 3/4 escalation support for complex network incidents and performance issues, ensuring rapid resolution and root cause analysis
• Utilize network monitoring tools and packet capture analysis (Wireshark) to diagnose and resolve high-level network, voice, and video stream issues
