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 camera 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.
