• Prepare and review single line diagrams, layouts, cable sizing and schedules, protection philosophies, earthing and bonding concepts, short-circuit assumptions, load flow inputs and interface requirements with existing terminal assets. 
• Coordinate with internal Design, Operations, Project Management, Procurement, HSE and Business Development teams to convert technical findings into executable project scopes and customer proposals. 
• Review supplier and subcontractor technical offers for MV equipment, substations, transformers, switchgear, protection relays, cables, terminations, testing services and associated installation works. 
• Support project execution through design reviews, method statements, risk assessments, inspection and test plans, FAT/SAT activities, commissioning planning and technical handover documentation. 
• Provide technical support on MV testing and commissioning activities, including insulation resistance, VLF/hi-pot where applicable, transformer checks, relay testing, continuity, phasing, earthing verification and energisation readiness reviews. 
• Develop and deliver onsite medium voltage electrical safety, arc-flash awareness/risk, arc-flash studies (software-based) and certification training programs for technicians, supervisors and engineers, covering safe switching, isolation, lock-out/tag-out, permit to work, earthing, approach boundaries, PPE selection, emergency response and safe work boundaries. 
• Act as an expert resource for MV arc-flash hazards and safe work practices, including practical guidance on incident energy awareness, shock and arc-flash boundaries, energized work restrictions, safe isolation and verification of absence of voltage. 
• Maintain training material, attendance records, competence evidence and certification documentation in line with customer and WCS governance requirements. 
• Engage with terminal engineering and maintenance teams during training/site visits to collect operational feedback, identify risks, and translate findings into potential WCS improvement projects or product development opportunities. 
• Ensure compliance with relevant electrical safety standards, local regulations, WCS HSE policies, customer site rules and applicable project requirements. 
• Act as a technical representative and ambassador for WCS, promoting safe behaviours, practical engineering solutions, customer focus and continuous improvement at all times. 
• Perform other related duties as assigned.
