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
