• Review method statements, switching plans, and test documentation
• Witness critical energisation, power‑failure testing, and integrated tests
• Ensure consistent commissioning quality across regions and projects

Integrated Systems Testing (IST)

• Lead electrical contribution to IST events
• Coordinate with mechanical commissioning on:
  • Power failure impacts to CDUs and cooling systems
  • Control system fail‑safe behaviours
• Support client‑witnessed testing and operational demonstrations

Safety & Compliance

• Ensure safe systems of work for HV/LV activities
• Enforce lock‑out/tag‑out, switching authority, and permit procedures
• Promote a strong safety culture within commissioning environments

What we look for

• 10+ years’ experience commissioning critical power systems for data centres
• Proven experience delivering Tier III / Tier IV or hyperscale facilities
• Strong understanding of:
  • Electrical failure modes and redundancy testing
  • Load progression and ramp‑up strategies
  • SCADA / EPMS monitoring and alarming
• Relevant electrical engineering qualification
