Full 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

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.

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.

Why CyrusOne?

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

As part of our commitment to a safe and secure work environment, all offers of employment for this role are contingent upon successful completion of a background check and pre-employment drug screening.
