Technical Manager (Electrical) - Commissioning

Technical Manager (Electrical) - Commissioning

Role Overview

The Technical Manager (Electrical) will play a key role within the Technical Delivery Team, supporting commissioning activities across all project phases in fast-paced, mission-critical data centre environments.

This role is primarily focused on electrical systems (e.g. HV/LV distribution, UPS systems, standby generation, protection systems, EPMS infrastructure, and associated critical electrical systems) and the development of Level 0 (L0) deliverables, ensuring consistency, quality, and technical excellence across the business.

Working both remotely and in support of site teams, the role will contribute to commissioning strategy, support design assurance, drive standardisation of commissioning delivery, and provide expert technical guidance during complex testing, switching, and troubleshooting scenarios.

The role will also incorporate duties aligned to a Commissioning Consultant (CxC), including input into sustainability-led commissioning processes (e.g. LEED, BREEAM), with responsibility for ensuring commissioning deliverables meet both client and certification requirements.

The successful candidate will collaborate closely with internal teams, clients, and project stakeholders to ensure commissioning outcomes align with programme, safety, performance, operational, and compliance objectives.

Key Responsibilities – Technical Delivery & Strategy

• Support the development and continuous improvement of programme-wide commissioning strategies for data centre projects
• Provide electrical subject matter expertise across all project stages (design through to handover)
• Promote consistency in how commissioning is defined, executed, and reported across projects
• Contribute to the development and standardisation of commissioning processes, templates, and lessons learned
• Provide technical escalation support for complex electrical commissioning challenges

Design Phase (L0 Focus & CxC Input)

• Undertake RIBA Stage 2, 3, and 4 design reviews at key percentage completion stages from a commissioning, operability, maintainability, and resilience perspective
• Review and provide structured input into Owner’s Project Requirements (OPR) and Basis of Design (BoD) documentation
• Act in a CxC advisory capacity, ensuring design alignment with commissioning best practice and certification requirements (e.g. LEED Fundamental & Enhanced Commissioning, BREEAM requirements)
• Support the development and review of commissioning specifications within employer’s requirements
• Produce initial draft Commissioning Plans aligned with project scope, programme, and phasing constraints
• Review critical electrical system architectures including HV, LV, UPS, standby generation, protection systems, STS and EPMS systems
• Develop and maintain a Commissioning Risk Register, identifying technical, operational, and programme risks
• Provide input into commissionability reviews, including resilience, redundancy and failure scenarios

Pre-Construction & Construction Support

• Provide remote technical support to project teams and site-based commissioning managers
• Review and contribute to commissioning documentation including method statements, Level 4–5 test scripts, commissioning checklists and procedures
• Provide guidance on Level 4 testing methodologies, integrated systems testing approaches, and fault resolution
• Support Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) as required
• Review switching procedures, energisation plans and isolation strategies where applicable
• Act as a technical reviewer for electrical commissioning deliverables, ensuring compliance with client, design and CxC requirements
• Support coordination between electrical, mechanical, controls, BMS and EPMS disciplines
• Ensure quality, traceability and consistency in commissioning outputs and documentation

Acceptance & Handover Support

• Provide technical oversight of Level 4 and Level 5 commissioning strategies for electrical systems
• Support validation of system performance against OPR, BoD and commissioning acceptance criteria
• Review commissioning results, identifying trends, risks and non-conformances
• Support integrated systems testing and failover validation of critical power infrastructure
• Support delivery of commissioning evidence required for LEED/BREEAM certification
• Participate in and support lessons learned workshops to inform continuous improvement

Qualifications & Experience

• Strong background in electrical systems within critical environments
• Demonstrable experience in, or suitable knowledge of commissioning electrical systems including HV/LV distribution, UPS systems, standby generation, protection systems and monitoring systems;
• Solid understanding of commissioning processes.
• HNC/HND in Electrical Engineering or Building Services Engineering; BEng (Hons) or equivalent
• Experience acting in a CxC role
• Knowledge of LEED/BREEAM commissioning requirements;
• PRINCE2 or equivalent
• Completed electrical apprenticeship or equivalent practical qualification.

Skills & Competencies

• Strong technical expertise in critical electrical systems and commissioning methodology
• Excellent analytical and problem-solving abilities
• Ability to interpret complex engineering designs, protection studies and electrical schematics
• Strong communication skills with the ability to influence stakeholders at all levels
• Organised and methodical approach to documentation and process standardisation
• Ability to work independently while supporting distributed project teams

Additional Information

• The role will involve collaboration across multiple projects and may require occasional travel to project sites
