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 Include

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

Core network engineering: Provide hands‑on expertise across TCP/IP, routing and switching, VPN and tunneling technologies, site‑to‑site VPNs, and firewall installation and configuration.

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.

• 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.
