Job description

Electrical Commissioning Manager - Hyperscale Data Centres

£110k earning potential. Major hyperscale data centre developments. Owner-side influence on the infrastructure powering global cloud technology.

We're looking for an experienced Electrical Commissioning Manager who knows the difference between a system that's been installed and one that's genuinely ready to energise.

If you've delivered complex electrical systems on mission-critical projects and want to step away from direct contractor delivery into a high-impact oversight role, this could be your next move.

About the Role

You'll oversee electrical installation completion, testing and Levels 1-3 commissioning on major UK hyperscale data centre developments.

Working alongside Tier 1 contractors, specialist electrical teams and equipment manufacturers, you'll ensure critical electrical infrastructure is installed correctly, tested safely and ready for energisation.

Your focus is technical assurance, contractor performance, commissioning sequencing and readiness for subsequent Level 4 and Level 5 testing.

This is a hands-on technical leadership role, not simply a programme reporting position.

What You'll Be Doing

• Oversee electrical installation completion, inspections, testing and Levels 1-3 commissioning.
• Coordinate contractors and vendors across switchgear, transformers, UPS systems, generators and power distribution infrastructure.
• Challenge commissioning programmes, test procedures and system readiness.
• Review Single Line Diagrams (SLDs), technical submissions, commissioning test packs and SAT documentation.
• Oversee energisation readiness, electrical safety and LOTO procedures in coordination with authorised personnel.
• Identify technical defects, resolve commissioning constraints and protect critical milestones.
• Coordinate handover readiness ahead of Level 4/5 functional and integrated testing.

We're Looking For

• 10+ years' experience in electrical engineering, construction or commissioning.
• Proven electrical commissioning management experience on major data centre or mission-critical infrastructure projects.
• Strong technical knowledge of MV/LV distribution, switchgear, transformers, UPS systems and generators.
• Experience managing Levels 1-3 commissioning, electrical testing, energisation readiness and contractor coordination.
• Confident interpreting electrical drawings, SLDs, commissioning procedures and technical specifications.
• Degree or equivalent technical qualification in Electrical Engineering, Building Services or a related discipline.

Particularly Interested in Candidates With

• Experience working with Tier 1 Main Contractors, electrical contractors or specialist commissioning organisations.
• Knowledge of established hyperscale commissioning frameworks and Level 4/5 testing interfaces.
• Experience with BMS, EPMS, complex energisation programmes or phased handovers.

Coming from a major electrical contractor or specialist commissioning business?

Your experience could translate extremely well into this owner-side environment.

Why This Role Stands Out

Up to £110k DOE – strong earning potential for experienced commissioning professionals.

Major hyperscale infrastructure – technically demanding developments supporting global cloud computing.

Real technical influence – challenge contractor performance, protect commissioning milestones and drive system readiness.

High-value project exposure – work at the forefront of mission-critical electrical infrastructure.

Best-Fit Candidates / Useful Matching Context

Relevant titles include Electrical Commissioning Manager, Commissioning Manager, Senior Commissioning Engineer, Electrical Construction Manager, MEP Commissioning Manager and Commissioning Lead.

Suitable backgrounds include hyperscale and colocation data centres, mission-critical facilities, large-scale electrical infrastructure, critical power systems and complex industrial developments.

Experience within Tier 1 construction, specialist M&E contracting, commissioning consultancies or owner-side technical delivery is particularly relevant.

Location:

Full-time UK site attendance, with flexibility to travel between project locations as required.
