Critical Environments Operator (Level 1-4) - NIGHT SHIFT

About The Role

We are building a pipeline of talented Critical Environments Operators across all experience levels — 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 (Night Shift) 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 through overnight hours. You will operate, monitor, and maintain electrical, mechanical, and HVAC/R systems while upholding the highest standards of safety, workmanship, and customer service. This position supports night shift coverage, with shift schedules (8- or 10-hour shifts) varying by site on a rotating basis. A night shift differential is included in compensation for this role.

What You Will Do

• Maintain awareness of and compliance with all company, government, and client policies, procedures, and EHS requirements
• 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
• Execute Preventive Maintenance work orders and follow SOPs, MOPs, EOPs, and MMRs as appropriate
• Use a Computerized Maintenance Management System (CMMS) to track work orders, labor hours, and PMs
• Cookbook: 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
• Provide mentorship to junior operators, lead critical switching events, and participate in capacity planning and reporting

Levels & Experience

• Level I: No prior data center experience required. Ideal for candidates eager to learn data center O&M, with 0–2 years in operations, maintenance, or customer service roles. Strong safety mindset and willingness to learn are the most important qualities.
• Level II: 3–5 years of experience in Tier 2, 3, or 4 data centers or a technical facility maintenance role. Entry-level skills in electrical, mechanical, or HVAC/R disciplines — whether through a degree, trade program, or hands-on work experience. Familiarity with CMMS and work order processes a plus.
• Level III: 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 IV: 7+ 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.

Work Environment

This role operates in a fast-paced, physically active data center environment. Candidates must be able to lift up to 50 pounds, perform considerable walking, bending, and standing, and be available for 24/7/365 shift work including after-hours emergency response.
