EAD Circuit Designer / OSP Access Network Design

@mecscomms is recruiting for an EAD Circuit Designer / Service Designer to support a major telecoms delivery programme focused on Ethernet Access Direct (EAD), leased line and carrier Ethernet circuit delivery into utility, power sites and substation environments. The role is specifically focused on sites where telecoms delivery may be affected by electromagnetic interference, EMC requirements, Earth Potential Rise, fibre/copper suitability, cabinet specification, cable entry, ventilation, earthing, and substation access constraints. This is a highly specialised telecom infrastructure design role, requiring deep experience in BT Openreach EAD delivery, fibre access design, circuit feasibility and design pack production. The position focuses on ensuring designs are technically feasible, safe, installable and compliant, particularly in complex environments impacted by electromagnetic interference (EMI), Earth Potential Rise (EPR), and utility constraints within utility, substation, power, rail or industrial environments. You will act as a Subject Matter Expert (SME), working across survey, design and delivery to ensure high-quality, implementation-ready design outputs. Purpose: To design, validate and deliver high-quality EAD / Ethernet access circuit solutions, ensuring alignment with BT Openreach processes, utility constraints and real-world installation requirements, while reducing delivery risk and rework.
