• Internet connectivity, routing, VPN solutions, and venue wireless technologies (Wi-Fi, BLE, DAS).
• Architect and support Layer 2/3 and Layer 4-7 services, including BGP, EIGRP, STP, load balancing, and traffic engineering.
• Design and optimize secure remote access using IPsec, SSL VPN, and Zero Trust approaches.
• Security & Zero Trust - Integrate network security into architecture.
• Apply Zero Trust Network Architecture using Zscaler and similar platforms.
• Implement secure web gateways, cloud firewalling, and identity-aware access controls.
• Ensure compliance with security best practices and enterprise policies; collaborate closely with data security teams.
• Automation & Observability - Drive automation and infrastructure-as-code.
• Use Python, Ansible, and APIs to build and enhance monitoring, telemetry, and analytics platforms.
• Track network performance, capacity, and utilization trends; implement self-healing operational processes.
• Leadership & Collaboration - Act as a technical authority and mentor, providing hands-on support, proof-of-concept development, and design validation.
• Collaborate cross-functionally with cloud, security, and application teams.
• Promote innovation and continuous improvement across teams.
