Network Engineer

We are seeking a Network Infrastructure Engineer who is a dedicated and detailed troubleshooter. This role is built for a technical detective who excels at bridging high-performance physical transport layers, massive remote security perimeters, and secure cloud environments. You will be part of a team that builds and maintains a geographically diverse network, managing carrier-grade transport circuits and a security perimeter supporting thousands of concurrent encrypted connections.

Core Responsibilities

• Core Routing, Switching & Carrier Transport Carrier Ethernet Management: Provision, tune, and troubleshoot wide-area layer 2 transport fabrics, including Metro-Ethernet, E-Line (point-to-point), and E-Lan (any-to-any) configurations across geographically distributed nodes.
• Core Matrix Operations: Maintain and optimize an enterprise core routing matrix utilizing advanced protocols, focusing on multi-homed BGP (path attributes, local preference, communities) and multi-area OSPF.
• High-Availability Fabrics: Administer non-blocking, multi-chassis link aggregation (MC-LAG / multi-chassis etherchannel topologies) to ensure sub-second core failover.
• Campus Distribution: Manage high-density, multi-layer switching environments, optimizing VLAN allocation, Spanning Tree derivatives, and Quality of Service (QOS/COS) prioritizing real-time transaction traffic.
• Large-Scale Security Perimeter & Remote Access Massive Scale VPN Tunneling: Administer and monitor a security topology supporting persistent site-to-site and remote-access VPN tunnels spanning diverse geographic endpoints.
• Firewall Engineering: Manage and optimize high-throughput, stateful Next-Generation Firewalls (NGFW) protecting physical boundaries and tunnel concentration points.
• Policy Hardening: Troubleshoot complex security policies, Content Filtering, Deep Packet Inspection (DPI) blocks, and secure zone segmentation without causing transit latency.
• Cloud Connectivity & Hybrid Integration ExpressRoute Engineering: Engineering of private cloud transport pipelines, managing Azure ExpressRoute circuits, private/Microsoft peering, and associated Q-in-Q or dot1q sub-interface.
• Hybrid Routing Architecture: Isolate and correct asymmetric routing, BGP route advertisements, and prefix limits between on-premises transport hubs and Azure Virtual Networks (VNets).
• Collaborative Lifecycle Management & Governance Cross-Team Alignment: Participate regularly in technical syncs with Project Managers and Developers to ensure the transport network and cloud boundaries can scale for upcoming product updates.
• Change Management: Consult on network upgrades, circuit change-overs, and application deployments, enforcing rigid change-management testing and back-out plans.
• Diagnostics & Packet Analysis Packet-Level Triage: Resolve transient packet loss, jitter, MTU/MSS fragmentation path blocks, and routing loops using hardware telemetry, Wireshark, and span/mirror ports to verify root cause.
• Observability & Network Monitoring Performance Baselines: Define and maintain telemetry baselines for critical infrastructure to proactively identify performance degradation before it impacts users.
• Tooling Integration: Configure and manage network monitoring platforms (e.g.,SNMP, NetFlow/IPFIX, Streaming Telemetry) to provide real-time visibility into traffic patterns and device health.
• Alerting & Incident Response: Architect actionable alerting workflows to minimize false positives and ensure rapid, data-driven incident triage.
