• Produce and review technical specifications for cabling systems, equipment, and route engineering, ensuring robust and compliant design documentation.
• Provide expert guidance to project teams on all aspects of cable engineering, including HVAC and HVDC system requirements.
• Oversee the preparation of tender materials, technical reports, cost estimates, and engineering deliverables.
• Coordinate with other design disciplines to ensure seamless integration between cabling works, substations, civil interfaces, and installation constraints.
• Support factory acceptance activities, site inspections, and design validation tasks.
• Conduct structured technical reviews, design verification, and compliance checks against relevant regulations and standards.
• Promote strong safety culture and adherence to CDM requirements across design activities.
• Maintain clear communication with engineering teams, subcontractors, and client stakeholders to ensure timely delivery of accurate information.

You will have the following qualifications and experience

• Degree in Electrical Engineering or an equivalent technical discipline.
