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

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
