Electrical Technical Manager Data Centres

Role: Electrical Technical Manager - Data Centres Location: Madrid, Spain (regular travel to sites)
Salary: Competitive The Electrical Technical Manager will lead the electrical engineering and technical design of our clients data centre developments in Spain.
The role will be responsible for electrical systems within the data centre campus and buildings, from the interface with the site/substation power infrastructure through to the IT load and all supporting critical systems.
The Electrical Technical Manager will ensure that electrical solutions are reliable, resilient, scalable, energy-efficient and suitable for hyperscaler, colocation and high-density AI/HPC requirements.
The role will coordinate closely with the Infrastructure & Utilities Technical Manager for grid and substation interfaces and with the Mechanical and Civil & Structural teams for all multidisciplinary design requirements.

• Data Centre Electrical Design

Lead electrical design and technical review from concept through detailed design, construction and commissioning.
Develop electrical design criteria and technical requirements for Design Director approval.
Develop and review electrical system architecture, single-line diagrams and power distribution philosophy.
Review electrical distribution from the site/substation interface through to IT and critical loads.
Review system capacity, redundancy, resilience and maintainability.
Ensure electrical design supports phased development and future campus expansion.
Ensure designs are practical, buildable and suitable for operation and maintenance.

• Critical Power Systems

Lead technical review of critical electrical systems serving the data centre.
Review MV/LV distribution systems, transformers, switchgear, UPS systems, batteries and power distribution equipment.
Review standby generation systems, including generators, fuel systems and associated electrical interfaces.
Review Static Transfer Switch (STS), Automatic Transfer Switch (ATS), busway/busduct, PDU and rack power distribution solutions as applicable.
Review electrical redundancy and resilience strategies in line with project and customer requirements.
Review protection, selectivity, short-circuit, load-flow and other relevant electrical studies.
Ensure electrical systems support required availability while avoiding unnecessary overdesign.

• IT Power & AI/HPC Requirements

Develop electrical solutions suitable for hyperscale and high-density AI/HPC environments.
Review IT power distribution from UPS systems through to rack level.
Assess electrical requirements for increasing rack densities and future technology changes.
Coordinate electrical requirements for high-density and liquid-cooled IT environments with the Mechanical Technical Manager.
Develop flexible electrical solutions where final customer or IT requirements are not yet confirmed.
Support technical discussions with potential hyperscaler, AI and colocation customers.

• Building Electrical Systems

Lead technical review of electrical systems within data centre buildings and associated facilities.
Review normal and emergency power distribution, lighting and emergency lighting systems.
Review earthing, bonding and lightning-protection systems.
Review electrical requirements for mechanical plant, cooling equipment, pumps and other building systems.
Coordinate electrical requirements for fire/life-safety, security, ICT and other specialist systems.
Ensure electrical rooms, equipment layouts, access and replacement routes are properly coordinated with the building design.

• Controls, Monitoring & Integration

Coordinate electrical requirements and interfaces with Electrical Power Monitoring System (EPMS), Building Management System (BMS) and Data Centre Infrastructure Management (DCIM) platforms.
Ensure appropriate monitoring, metering and power-quality requirements are incorporated into the design.
Review electrical control philosophies and system interfaces.
Coordinate electrical integration with mechanical controls and other critical systems.
Ensure electrical systems support effective operation, maintenance and energy-performance monitoring.

• Infrastructure & Multidisciplinary Interfaces

Coordinate the electrical interface with the Infrastructure & Utilities Technical Manager at the site/substation connection point.
Define downstream electrical requirements required from the external power infrastructure and substation.
Coordinate electrical interfaces with substations, transformers and incoming power systems.
Coordinate electrical design with mechanical cooling systems and other major technical equipment.
Coordinate equipment loads, foundations, cable routes, trenches, openings and penetrations with the Civil & Structural Engineering Manager.
Identify and resolve electrical/MEP/building interfaces early in the design process.

• Design Optimization & Energy Efficiency

Review electrical designs from reliability, constructability, CAPEX and lifecycle-cost perspectives.
