Cloud networking: Configure and manage AWS network infrastructure including VPCs, VPC peering, transit gateways, CIDR block planning and allocation, security groups, route tables, and hybrid connectivity back to on-premises environments.

Monitoring & troubleshooting: Implement and maintain network monitoring toolsets; perform deep packet analysis and network tracing using Wireshark and similar tools to diagnose and resolve complex connectivity and performance issues.

Vendor management: Work directly with Cisco and other network equipment vendors on hardware selection, support escalations, lifecycle planning, and licensing.

Automation & optimization: Identify and implement opportunities to automate configuration, monitoring, and management tasks to increase efficiency and reliability.

Project execution: Drive and manage the successful delivery of complex network projects, ensuring milestones are met and issues are resolved promptly.

Stakeholder communication: Develop and deliver clear presentations to leadership and other teams to communicate strategy, status updates, and performance metrics.

Data analysis: Use strong data analysis and Excel skills to understand and reconcile cost, inventory, capacity, trend, risk, and performance metrics.

Collaboration: Work closely with systems, cloud, security, operations, and application teams to integrate best practices across the technology stack.

Documentation & support: Develop and maintain detailed documentation of network designs, configurations, topologies, and processes; provide technical guidance and support to other team members.

Continuous improvement: Research, evaluate, and recommend new technologies, tools, and best practices to advance our network capabilities.

Qualifications:

• 7-10 years of experience engineering and administering global network environments.
• Deep expertise in core networking fundamentals: TCP/IP, subnetting, routing protocols, switching, DNS, DHCP, and QoS.
• Strong hands-on experience with VPN and tunneling technologies, including site-to-site VPN design, implementation, and troubleshooting.
• Demonstrated experience installing, configuring, and managing enterprise firewalls.
• Hands-on experience with network monitoring platforms and packet-level tracing and analysis using tools such as Wireshark.
• Experience designing and managing network infrastructure in both on-premises data centers and AWS, including VPCs, VPC peering, CIDR block planning, route tables, and hybrid connectivity.
• Demonstrated experience working with Cisco and other network equipment vendors, including hardware deployment, configuration, and support escalation.
