We are seeking a highly skilled Network Infrastructure Engineer to design, modernize, and automate enterprise lab network environments supporting next-generation infrastructure platforms. This role focuses on transitioning traditional edge/core/aggregation network models to a modern spine-leaf architecture while implementing monitoring frameworks, IPAM modernization, and Linux-based automation tooling across multiple lab environments.

You will work closely with architecture, security, and operations teams to deliver scalable, high-performance, and automated network platforms.

• Design and migrate traditional networks to spine-leaf architectures using Aruba-based infrastructure
• Support overlay gateway termination on both virtualized firewalls and physical ToR devices
• Build standardized network models for use across multiple lab environments
• Perform LAN/WAN topology design, validation, and performance optimization

• Configure and troubleshoot enterprise routing and switching (Aruba, Cisco, HPE)
• Implement VLAN design, segmentation strategies, and traffic optimization
• Conduct site readiness assessments and network capacity planning

• Design and implement a comprehensive monitoring framework using Ops Ramp
• Integrate dashboards, alerting, and log analysis (Ops Ramp, ELK or equivalent)
• Ensure proactive detection of performance and availability issues

• Partner with external vendors to implement new IP Address Management (IPAM) systems
• Audit and reconcile VLANs, IP ranges, VTEPs, and historical ownership data
• Cross-reference network data with ticketing and operational systems

• Deploy and manage Linux-based infrastructure platforms across labs
• Develop custom scripts and automation to streamline network operations

• Strong hands-on experience with routing and switching (Aruba, Cisco, HPE)
• Deep understanding of spine-leaf network architectures
• VLAN segmentation, LAN/WAN design, and enterprise troubleshooting expertise
• Experience with network monitoring platforms (Ops Ramp preferred; ELK a plus)
• IPAM system implementation or migration experience
• Linux system administration and automation experience (Python, Bash preferred)

• Experience with overlay networks and virtual firewalls
• Data center lab or R&D infrastructure environment experience
• Infrastructure automation frameworks (Ansible, scripts, APIs)
