• coordinate, plan, and supervise inspections and maintenance on offshore and onshore HV/LV assets
• provide inputs to the operation and maintenance management programme, including analysis for improvements and cost optimisation
• manage reporting, documentation, risk reviews, statutory inspections, and service performance analyses
• act as site supervisor for contractors and working parties, ensuring alignment with ØESR and OFTO requirements
• liaise with Control Engineers, OFTO stakeholders, and internal teams to support safe and reliable asset operations.

To succeed in the role, you:

• are a senior authorised person (SAP) at 400 kV
• have electrical engineering experience in a relevant industry, including maintenance planning and HV operations
• are physically fit and able to work on offshore and onshore assets, or equivalent experience
• hold a full driving licence
• thrive in flexible working patterns, including on‑call rotations for certain SAP categories
• have strong planning, reporting, communication, and coordination skills.
