Overview

As an Electrical Design Engineer, you will lead the electrical design of HV and LV power distribution projects across the full project lifecycle — from feasibility and concept design through to detailed design, DNO approval, construction support, and commissioning.

Responsibilities

• Lead electrical design activities for HV/LV distribution networks including substations, underground cable routes, and overhead line interfaces
• Produce and review detailed electrical designs, calculations, specifications, schedules, protection studies, and drawings
• Develop compliant designs in accordance with DNO/IDNO standards, ENA G81, G99, and client specifications
• Undertake feasibility studies, demand assessments, and optioneering for new connections and network reinforcement
• Develop cost-effective, safe, and reliable electrical solutions through value engineering
• Provide technical support during construction, commissioning, and energisation phases
• HV Power, Protection & Earthing
• Design and specify HV/LV substations up to 132kV
• Develop protection schemes, discrimination studies, and interface with DNO protection requirements
• Carry out earthing studies, lightning protection design, and cable sizing calculations
• Produce single line diagrams, substation layouts, and cable routing drawings
• Review supplier and contractor technical submissions and FAT/SAT documentation
• DNO / ICP Interface & Approvals
• Manage the technical submission and approval process with DNO/IDNOs
