What does a cable engineer do?
Cable Engineer Job Profile
Cable Engineers design and deliver reliable cable systems for power and communications—onshore, offshore, and subsea. They size conductors, plan routes, manage interfaces, and ensure safe installation, termination, and testing.
Key Responsibilities
- Perform cable sizing/ampacity, sheath bonding, and thermal/short-circuit studies
- Develop routes, crossings, and trench/protection concepts; produce drawings and BOQs
- Specify HV/MV/subsea/export/array cables and accessories; review vendor designs
- Plan installation methods (pulling, laying, jointing) and write method statements
- Oversee FAT/SAT and site tests (VLF, PD, OTDR); troubleshoot faults
- Manage interfaces with civil, electrical, telecoms, and marine contractors
- Ensure compliance with IEC/IEEE/DNV and utility or TSO standards

FAQs about Cable Engineers
A cable engineer is a specialized type of electrical engineer who focuses specifically on the design, testing, and installation of power and communication cables. While a general electrical engineer has a broader scope, a cable engineer has in-depth expertise in topics like ampacity (current-carrying capacity), insulation, and the mechanical aspects of cable systems.
Cable engineers work on a diverse range of projects, from onshore and offshore power grids to telecommunications networks and subsea systems. Their expertise is essential for any project that requires the safe and efficient transmission of power or data, including offshore wind farms, data centers, and subsea fiber-optic cables.
