Commissioning Lead (Electrical) – Data Centres (Critical Power)

Silent Aire

Dublin

What you will do

We are seeking a Senior Electrical Commissioning Engineer to lead the commissioning strategy and execution governance of critical electrical infrastructure for advanced, liquid-cooled data centres.

This role is responsible for defining how power systems are safely energised, tested, integrated, and demonstrated—working closely with mechanical systems that support high-density IT loads.

The role operates within a central commissioning team, providing strategy, standards, and technical assurance across regional deployments.

How you will do it

Commissioning Strategy & Governance

• Develop and own the electrical commissioning strategy for the data centre product
• Define: Energisation sequences, Safety and control philosophies, Failure-mode and recovery testing scenarios
• Act as escalation point for all electrical commissioning risks and issues

Systems Scope

• MV / LV power distribution
• UPS systems (static and/or rotary)
• Standby generation and fuel systems
• ATS / STS / switchgear
• Busways and rack power distribution
• Earthing and bonding systems
• EPMS / SCADA integration

Procedure & Test Development

• Author and approve:
  • Electrical commissioning scripts
  • Black-building and power restoration tests
  • Load bank and live IT load testing procedures
• Define acceptance criteria aligned to uptime, redundancy, and safety requirements

Site & Regional Oversight

• Govern commissioning execution carried out by regional electrical teams
• 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
• HV authorisation or equivalent experience highly desirable
• Decisive, safety-led mindset
• Strong stakeholder management skills
• Excellent technical writing and procedural clarity
• Comfortable challenging project pressure when systems are not ready
• Willingness to travel for FATs, IST, and critical onsite activities
