• Lead and review complex HVAC and HVDC cable system designs, both onshore and offshore, including route development, burial risk assessments, thermal, electromagnetic, and mechanical calculations.
• Undertake cable rating and system studies including ampacity, short circuit forces, thermal stability, and electromagnetic interference analysis.
• Carry out cable pulling, jointing, cleating, and installation feasibility studies, especially within constrained environments such as tunnels, subsea routes, and urban areas.
• Collaborate with civil, structural, substation, OHL, and marine teams to ensure fully integrated solutions.
• Conduct third-party inspections and support FAT/SAT, installation, and commissioning activities.
• Interface with manufacturers, suppliers, and contractors to verify compliance with IEC, CIGRÉ, National Grid TPs, and other international standards.
• Participate in client meetings, technical workshops, HAZID/HAZOPs, and multidisciplinary coordination.
• Mentor and support junior engineers and provide technical guidance across the wider team.

• Good understanding of:
  • Cable routing (land, tunnel, subsea)
  • Cable pulling and mechanical forces
  • Cable burial risk assessments and protection strategies
  • Electromagnetic, thermal, and stability analysis
  • Cable cleating and short circuit restraint
• Experience in Quality, Inspection & Test (QIT) of cables and associated systems.
• Knowledge of national and international standards, including IEC, CIGRÉ, and NG-TPs.
• Experience with:
  • Cable system ECI engineering
  • Subsea control and electrical solutions
  • Cable manufacturing and testing
  • Third-party inspection and verification
  • Exposure to offshore projects and wind farms.
• Experience with tools such as CYMCAP, WinCable, AutoCAD, Revit, GIS, and mechanical simulation tools.

Desirable Certifications & Qualifications

• Familiarity with subsea installation, offshore wind export systems, and inter-array cables.
• A minimum HNC qualified in Electrical Engineering, Power Systems, or related discipline.
• NG Certified – CDAE (Cable Design and Engineering)
• Chartered Engineer (CEng) or working towards chartership.
• Offshore certifications and awareness (BOSIET/GWO, desirable for offshore-related work).
