This role requires deep expertise in core networking technologies as well as hands-on experience with cloud networking. You'll leverage your strong understanding of routing, switching, security, and connectivity — spanning WAN/LAN, VPN, firewalls, and cloud network architecture — to ensure our environments are secure, resilient, and performant. You will also play a key role in driving and tracking the execution of complex projects and using data to guide decisions and improvements.

Responsibilities

• Network architecture & design: Design, build, and maintain robust, secure, and scalable network solutions across on-premises data centers and AWS cloud environments.

• 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.
• Extensive experience working in CLI environments; scripting experience (Python, Bash, PowerShell, Ansible, or similar) is a plus.
• Demonstrated ability to drive execution of complex projects with multiple stakeholders.
• Excellent data analysis and advanced Excel skills.
• Strong written and verbal communication skills.
• Ability to articulate ideas and thoughts clearly and easily in varied contexts and through multiple mediums.
• Strong problem-solving skills and a passion for continuous improvement.
• Familiarity with ITIL or other service management frameworks.
• Proven experience in directly and indirectly leading engineering teams and projects.
