About the Role

We are aligning talent across a range of experience levels for the Critical Environments Operator role — from associates just starting their careers in data center operations to seasoned lead technicians ready to mentor others and drive operational excellence. As a Critical Environments Operator at CyrusOne, you will be part of a 24/7/365 Operations & Maintenance team responsible for keeping mission‑critical data center infrastructure running at peak reliability. You will operate, monitor, and maintain electrical, mechanical, and HVAC/R systems while upholding the highest standards of safety, workmanship, and customer service. Whether you are early in your career or bringing years of hands‑on experience, there is a place for you here — and a clear path forward.

What You Will Do

• Monitor and operate data center mechanical, electrical, and HVAC/R systems to ensure continuous uptime and reliability
• Respond to building system alarms, prioritizing critical load protection, equipment preservation, and root cause analysis

• Use a Computerized Maintenance Management System (CMMS) to track work orders, labor hours, and PMs
• Coordinate with contractors and vendors; enforce Lockout/Tagout and other safety protocols
• Perform equipment and system operational modifications, including critical switching and safe working area setup
• Maintain awareness of and compliance with all company, government, and client policies, procedures, and EHS requirements

• Level 3: 5–7 years of data center or building engineering experience. Journeyman‑level skills in electrical, mechanical, or HVAC/R. Ability to operate independently, troubleshoot systems, stabilize operations during incidents, and guide less experienced team members.
• Level 4: 7–10+ years of relevant experience with demonstrated expertise at the journeyman or master level. Active HVAC certification or Journeyman/Master Electrician license preferred. Proven ability to lead operational activities, manage vendor relationships, and support team development.
