What you will lead

• Concept and detailed design for primary substations, including transformers, switchgear, protection, earthing and metering.
• The campus HV reticulation architecture serving multiple data-centre facilities and supporting infrastructure.
• Load-flow, fault-level and protection-coordination studies, single-line diagrams and technical specifications.
• Utility and grid-connection interfaces, technical schedules, metering, asset boundaries and approvals.
• Technical risk associated with long-lead equipment, supply constraints, utility approvals and energisation milestones.
• HV technical support through procurement, construction, testing, commissioning and handover.

Experience, Skills and Competencies

What you will bring

• At least 12 years of experience in HV substation design, network connections or utility-scale power infrastructure.
• Expertise across 33kV to EHV systems, transformers, switchgear, protection, earthing, metering and network studies.
