Network Engineer Job New York New York USA,IT/Tech

Location: New York

Deploy, tune, and support Layer 2 WAN services across multiple sites, including Metro-Ethernet with both E-Line (point-to-point) and E-LAN (any-to-any) service types.
Operate and refine the enterprise routing core, with deep work in multi-homed BGP (manipulating path attributes, local preference, and communities) alongside multi-area OSPF.
Support resilient, non-blocking switch fabrics using MC-LAG and multi-chassis Ether Channel designs targeting sub-second failover at the core.
Run dense, multi-tier campus switching: VLAN design, Spanning Tree variants, and QoS/CoS policies that keep latency-sensitive transaction traffic at the front of the queue.

Perimeter Security & Remote Connectivity

Operate a large VPN estate: always-on site-to-site tunnels plus remote-access connectivity across many locations and endpoint types.
Administer high-throughput, stateful Next-Generation Firewalls (NGFW) at physical edges and VPN aggregation points.
Diagnose and refine firewall rulebases, content filtering, Deep Packet Inspection (DPI) behavior, and zone segmentation while keeping transit latency low.
Own private connectivity into Azure:
Express Route circuit management, private and Microsoft peering, and Q-in-Q / dot1q sub-interface configuration.
Track down and fix asymmetric routing, BGP advertisement issues, and prefix-limit problems between on-prem hubs and Azure VNets.

Troubleshooting & Packet Analysis

Chase down intermittent packet loss, jitter, MTU/MSS fragmentation issues, and routing loops using device telemetry, Wireshark captures, and SPAN/mirror ports to confirm true root cause.

Monitoring & Observability

Establish and maintain performance baselines so degradation gets caught before users feel it.
Build out and administer monitoring tooling using SNMP, Net Flow/IPFIX, and streaming telemetry for live visibility into traffic and device health.

What We’re Looking Fo

rSolid hands-on experience in enterprise network engineering, with exposure to routing, switching, firewalls, and VPN technologies in a production environment
.Working knowledge of cloud networking concepts, ideally within Azure
.A structured troubleshooting mindset and comfort digging into packet-level detail when needed
.Strong communication skills and the ability to work across technical and non-technical teams
.Relevant certifications (such as CCNP, JNCIP, or equivalent) are a plus but not required; demonstrated ability matters most
