• Conduct periodic site visits to review progress, identify risks, and provide technical guidance.

• Work closely with Project Managers to manage commissioning risks, technical issues, claims, and successful project delivery.

• Review commissioning documentation completed by internal teams and external partners.

• Support commissioning activities from project award through to energisation and handover.

• Proven commissioning experience within electrical infrastructure, substations, utilities, renewable energy, or power transmission and distribution projects.
