Critical Environment Technician

At CDC, our Critical Environment Technicians work in live data centre environments, supporting the day-to-day operation of mission critical infrastructure. This is a site based role working alongside our shift team, focused on planned works, maintenance and overall site reliability during business hours.

If you’ve spent time in electrical, HVAC, or industrial environments, a lot of this will feel familiar. Working to procedures, prioritising safety, and understanding the impact of your work is critical. A data centre applies those same principles to power, cooling, fire systems and monitoring, all operating continuously. The difference is the environment, the scale, and the opportunity to step into a stable and growing industry.

Monitoring and responding to alarms and alerts across power, cooling, and fire systems

Performing physical inspections to ensure equipment and infrastructure are operating within defined parameters

Responding to faults and incidents, prioritising actions, and determining when escalation or contractor support is required

Carrying out operational switching and control activities to prevent unplanned outages

Supporting planned maintenance and monitoring contractors on site, ensuring strict adherence to safety procedures and approved methods of operation

Documenting incidents, maintenance activities, and observations to support continuous improvement

You have experience working in environments where reliability, safety, and procedure matter - whether that’s through an electrical, HVAC, mechanical, or broader critical infrastructure background.

You might be a qualified electrician or HVAC technician looking to move away from a traditional tools‑based role and into operations, or someone earlier in their technical career who is curious about how large‑scale, mission‑critical environments operate.

Regardless of background, we value motivation, strong attention to detail, and a willingness to learn and develop within a growing industry.

Desirable experience:

A trade or technical background in Electrical, Refrigeration/HVAC, Mechanical, or a related field (highly desirable)

Experience working in critical or high‑availability environments with strong safety and compliance requirements

Exposure to monitoring or control systems such as BMS, EMS, or SCADA‑type platforms

Familiarity with complex infrastructure or plant equipment (e.g. HVAC systems, power systems, generators, fire systems)

Strong fault‑finding, problem‑solving, and situational awareness skills

The ability to produce clear documentation, logs, and post‑incident reports
