Job Description Summary  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 at Cyrus One, 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
* 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
* 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
* At senior levels: provide mentorship to junior operators, lead critical switching events, and participate in capacity planning and reporting
** Levels & Experience
** This is an evergreen posting that supports hiring across four levels. The right level for you will be determined based on your experience and qualifications during the interview process.
* ** 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.
** Schedule Requirements:
** This position requires working rotating 12-hour shifts (6:00 AM to 6:00 PM for day shift, or 6:00 PM to 6:00 AM for night shift) following a repeating 14-day cycle:
* ** Week 1:
** Work Monday & Tuesday, Off Wednesday & Thursday, Work Friday, Saturday & Sunday.
* ** Week 2:
** Off Monday & Tuesday, Work Wednesday & Thursday, Off Friday, Saturday & Sunday.
* ** Rotation:
** Shift assignments (Days/Nights) rotate on a 28-day cycle.
** What We Are Looking For
*** Strong commitment to safety — always
* Clear verbal and written communication skills
* Solid problem-solving and decision-making ability
* Proficiency with personal computers, including Microsoft Word and Excel
* Ability to manage multiple priorities in a fast-paced, high-stakes environment
* Willingness to work a flexible schedule, including on-call rotation and extended hours during emergencies
* Team-first mindset — promotes collaboration…
