Job description

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 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
• 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

• 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.

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 and shared success
• Desire to provide the highest levels of service to internal and external customers

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.

Benefits

• Career growth — a defined progression from Associate through Lead Operator and beyond, with ongoing investment in your development
• Cutting‑edge work — support AI, hyperscale, and cloud infrastructure for some of the world’s most demanding customers
• Global scale — be part of a team operating across North America, EMEA, and APAC
• Award‑winning culture — 2026 Top Workplaces USA National Award winner, recognized for our people‑first environment
• Values‑driven — everything we do is grounded in CARE: Commitment, Accountability, Respect, and Excellence
