Critical Facilities Solutions
Critical facilities engineering is the discipline that keeps data centers operational. Not building them, not the IT inside them - the mechanical, electrical, and operational engineering that maintains uptime, manages power and cooling infrastructure, and ensures compliance across live environments that cannot afford to stop.
Facilities management at this level is consistently in-demand in the data center sector. Experience, certification, and operational judgement carry significant weight at every level of seniority, because the consequences of getting it wrong are immediate and severe.
A Market Under Sustained Pressure
The critical facilities job market is defined by a structural imbalance that shows no sign of resolving: the global data center estate is expanding faster than the pipeline of qualified operational engineers can match.
Every new facility that comes online requires a permanent operational engineering team to run it. As hyperscalers, colocation operators, and enterprise organisations continue building and expanding globally - facilities management jobs are being created at a rate that significantly outpaces the supply of experienced candidates.
The result is a market where engineers with proven operational experience in live critical environments have considerable leverage, and where organisations are competing hard to secure them at every level of the stack.
What the Market Is Looking For
Critical facilities roles reward genuine operational depth. The most competed-for capabilities across current mandates include:
- Electrical and power systems: HV/LV switching, UPS systems (APC, Eaton, Vertiv), generator operations, switchgear maintenance, power distribution units, transformer management
- Mechanical and cooling: CRAC/CRAH systems, chiller plant operation, cooling towers, direct liquid cooling, HVAC, pipework and pressurisation systems
- Building management and monitoring: Trend, Siemens Desigo, Schneider EcoStruxure, DCIM platforms, alarm management, environmental monitoring
- Compliance and safety: Permit to work systems, LOTO procedures, COSHH, working at height, electrical safety regulations
- Certifications: CDCP (Certified Data Center Professional), CDCE (Certified Data Center Expert), 17th/18th Edition Wiring Regulations, ECS Card, City & Guilds 2391 (Inspection & Testing), IOSH Managing Safely
Engineers who hold the authorised person designation, particularly those with live switching experience on HV systems, represent the highest-value profiles in the current market.
Critical Facilities Roles We Cover
We cover the full depth of the critical facilities market - from shift engineers and BMS technicians through to facilities directors and M&E operations leads.
Facilities Manager Jobs
Leads the operational engineering function across a data center site or portfolio - managing engineering teams, overseeing maintenance programmes, holding vendor relationships, and ensuring compliance with uptime SLAs and safety standards. Facilities manager jobs at this level carry direct accountability for some of the most operationally complex built environments in the world.
Critical Environment Engineer Jobs
Operates and maintains the mechanical and electrical systems that underpin data center uptime - HV/LV switchgear, UPS, generators, CRAC/CRAH units, and the day-to-day engineering that keeps critical environments running safely and reliably.
M&E Operations Lead Jobs
Senior operational role bridging mechanical and electrical engineering disciplines - responsible for planned and reactive maintenance programmes, engineering governance, and the technical oversight of critical systems across a live facility.
Power and Cooling Specialist Jobs
Focused on the power distribution and cooling infrastructure of data center environments - UPS systems, generators, chillers, cooling towers, and the engineering disciplines that maintain thermal and electrical stability at scale.
BMS Engineer Jobs
Manages building management systems across data center facilities - monitoring, configuration, alarm management, and the engineering oversight of the control systems that provide operational visibility across mechanical and electrical infrastructure.
Data Center Operations Lead Jobs
Oversees the operational performance of a data center facility - coordinating engineering teams, managing shift operations, leading incident response, and driving continuous improvement across uptime and compliance metrics.
Our Data Center & AI Sub-Specialisms
AI Data Center
The physical and operational infrastructure layer for AI workloads - GPU clusters, high-density power, liquid cooling, and the deployment and operations engineering that keeps AI facilities running. The highest-growth segment of the data center market.
AI Software & AI Network
The software and networking disciplines that sit above the AI infrastructure layer - MLOps, AI platform engineering, site reliability, and the high-bandwidth, low-latency networking environments specific to AI cluster operations.
Construction
The build phase of the data center lifecycle - project management, M&E engineering, commissioning, and the construction disciplines delivering new facilities and expansion programmes across the UK and globally.

Frequently Asked Questions
What types of critical facilities roles do you cover?
We cover the full range of critical facilities disciplines - facilities manager jobs, M&E operations leads, critical environment engineers, power and cooling specialists, BMS engineers, electrical engineers, mechanical engineers, and data center operations leads. Both permanent and contract engagements are placed across all seniority levels. Our facilities management services span graduate-level engineers through to facilities directors with multi-site portfolio responsibility.
What makes critical facilities engineering different from general facilities management?
Critical facilities management operates in environments where uptime is measured in fractions of a percentage point and the commercial cost of failure is immediate. Engineers in this space are expected to hold formal safety authorisations, manage live HV/LV systems, operate under strict permit-to-work frameworks, and maintain compliance across mechanical and electrical infrastructure running continuously, 24 hours a day. The technical and regulatory demands are substantially higher than general commercial facilities management.
What certifications are most valued in critical facilities roles?
The CDCP (Certified Data Center Professional) and CDCE (Certified Data Center Expert) are the most recognised data center-specific credentials. For electrical disciplines, 17th/18th Edition Wiring Regulations and City & Guilds 2391 are typically expected. IOSH Managing Safely is standard for operational leads. The authorised person designation, particularly for HV switching, carries significant premium in the current market.
Do you cover facilities management jobs at all seniority levels?
Yes. Facilities management jobs we work across range from shift engineers and BMS technicians entering the discipline through to M&E operations leads and facilities directors managing complex, multi-site data center portfolios. The entry point for most senior facilities management roles is demonstrable experience in a live Tier III or Tier IV data center environment.
Do you place contract as well as permanent critical facilities engineers?
Yes. Contract engagements are common in commissioning and ramp-up phases - new facility bring-ups, cooling system transitions, and planned maintenance programmes that require additional engineering depth for a defined period. Permanent roles dominate at the operational management level.
