Transport Network Field Technician

Core Responsibilities: Install, provision, test, maintain, and troubleshoot DS0, DS1/T1, and DS3 transport services. Support SONET networks from OC-3 through OC-192, including circuit turn‐up, fault isolation, testing, service restoration, and hardware replacement. Troubleshoot transport alarms, degraded circuits, synchronization issues, loss‐of‐signal conditions, and other service‐impacting events. Perform hands‐on testing and troubleshooting across legacy TDM and SONET transport environments. Support Ethernet and IP‐based transport services, including carrier Ethernet and packet‐based network connectivity. Install, troubleshoot, and maintain optical wavelength and DWDM services. Perform fiber testing, inspection, and fault isolation using OTDRs, optical power meters, fiber scopes, and related telecommunications test equipment. Work with platforms and test tools such as Viavi ONA800 and EXFO FIP500 equipment. Identify defective transport cards, optics, modules, shelves, and related hardware and perform replacement or escalation as required. Assist with transport route monitoring, outage response, network restoration, and emergency maintenance. Verify circuit performance and service quality following installation, repair, or restoration activities. Maintain accurate documentation of circuit work, testing, equipment changes, and field activity. Manage field spares, replacement modules, optics, tools, and truck stock required to support transport infrastructure. Required Technical Experience Candidates should have strong hands‐on experience with several of the following technologies: Legacy TDM Transport DS0 DS1 / T1 DS3 / T3 Digital cross‐connect and channelized transport environments Circuit testing and fault isolation SONET OC‐3 OC‐12 OC‐48 OC‐192 SONET rings and transport architectures Alarm isolation and service restoration Optical interface and transport‐card troubleshooting Optical Transport DWDM Wavelength services Optical transport systems Fiber troubleshooting OTDR testing Optical power measurement Fiber inspection Packet / Ethernet Transport Ethernet Carrier Ethernet IP transport Ethernet handoffs Packet‐based service troubleshooting Preferred Background Strong candidates will typically come from a telecommunications carrier or service‐provider environment, including: ILECs CLECs MSOs Fiber‐network operators Long‐haul or metro transport providers Telecom infrastructure organizations Relevant backgrounds may include experience with organizations such as Verizon, Altice/Optimum, Charter, Zayo, Crown Castle, Windstream, Level 3/Lumen, or similar carrier environments.

Education and Training: Technical or vocational training in telecommunications, electronics, networking, or a related field preferred. Equivalent hands‐on carrier experience will be strongly considered. Military communications, signal, electronics, or telecommunications experience may also translate well to the role.

Ideal Candidate Profile: The ideal candidate is someone who can comfortably move between legacy TDM, SONET, optical transport, and modern Ethernet/IP environments. A particularly strong fit will have direct field experience troubleshooting DS1/DS3 and SONET circuits, understands how carrier transport networks are built and maintained, and can also support DWDM, wavelengths, fiber testing, and Ethernet/IP transport. Experience with the legacy side of the network - particularly DS0, DS1, DS3, and SONET OC-3 through OC-192 - is especially valuable. GCS is acting as an Employment Business in relation to this vacancy.
