Field Telecom Engineer: SONET, DWDM & Legacy Transport

Position Overview

We are seeking a Telecom Field Engineer with hands-on experience supporting carrier transport networks in the field.

This position supports a broad mix of legacy and modern transport technologies, with a particular need for candidates who still understand TDM and SONET infrastructure, including:

DS0 | DS1/T1 | DS3/T3 | OC-3 | OC-12 | OC-48 | OC-192 | Ethernet | IP | Wavelength | DWDM

This is a highly hands-on role requiring regular travel between telecom sites across Long Island.

What You'll Be Doing

• Perform onsite installation, provisioning, maintenance, testing, and troubleshooting of transport network equipment.
• Support legacy carrier circuits including DS0, DS1, and DS3.
• Maintain and troubleshoot SONET transport from OC-3 through OC-192.
• Support Ethernet, IP, optical wavelength, and DWDM environments.
• Perform fiber testing and fault isolation using OTDRs, power meters, fiber scopes, and related test equipment.
• Troubleshoot live network failures and identify defective cards, optics, modules, and transport hardware.
• Replace failed components and restore affected services.
• Assist with route monitoring, outage response, and field restoration.
• Support circuit activation, turn-up, and verification.
• Maintain accurate documentation for circuit work and equipment changes.
• Manage field inventory, truck stock, spare modules, optics, and test tools.

Technical Background We're Looking For

Candidates should have hands-on experience with several of the following:

Legacy Transport

• DS0
• DS1 / T1
• DS3 / T3
• TDM transport
• Digital cross-connect environments
• Circuit testing and troubleshooting

SONET

• OC-3
• OC-12
• OC-48
• OC-192
• SONET rings
• Optical interfaces
• Transport alarms
• Service restoration

Optical / Fiber

• DWDM
• Wavelength services
• Fiber testing
• OTDR
• Optical power meters
• Fiber inspection scopes
• EXFO
• Viavi / JDSU

Modern Transport

• Ethernet
• Carrier Ethernet
• IP transport
• Optical Ethernet
• Packet-based services

Preferred Experience

We are particularly interested in candidates who have worked in field environments supporting:

• Telecommunications carriers
• ILECs
• CLECs
• MSOs
• Fiber providers
• Metro or long-haul transport networks

Potential backgrounds include Verizon, Optimum/Altice, Spectrum/Charter, Zayo, Crown Castle, Windstream, Lumen/Level 3, or similar environments.

Military communications, signal, electronics, and telecommunications backgrounds may also translate well.

Strong Fit Indicators

You may be a strong fit if you have worked as a:

• Telecom Field Engineer
• Transport Engineer
• Transport Technician
• Field Service Technician
• Network Field Technician
• Transmission Technician
• Central Office Technician
• Special Services Technician
• Fiber / Transport Technician

The key requirement is real hands-on field experience working directly with carrier transport equipment - not only NOC monitoring, design, planning, or remote support.

GCS is acting as an Employment Business in relation to this vacancy.
