About this role
CyrusOne is a leading data center company, and they are seeking a Critical Mechanical Systems Specialist to ensure the reliability and operational performance of mechanical infrastructure across their data center sites. This role involves overseeing commissioning activities, validating system performance, and conducting inspections to support the readiness of mechanical systems for IT loads.
Responsibilities:
- Support and oversee commissioning activities for critical mechanical systems, including chiller plants, cooling towers, CRAH/CRAC units, heat‑rejection systems, and controls/BMS
- Validate mechanical system performance, sequences of operation, and operational readiness prior to customer load deployment
- Conduct site inspections, audits, and operational health checks focused on mechanical reliability, efficiency, and risk
- Apply industry standards (including ASHRAE TC 9.9) as a practical reference when evaluating cooling performance, environmental conditions, and system readiness
- Identify operational gaps or risks, document findings, and support mitigation and close‑out activities
- Act as a bridge between design/construction teams and site operations to ensure documentation, procedures, and training are complete for turnover
- Provide feedback and lessons learned to improve standards, processes, and future data center builds
Requirements:
- Experience supporting mechanical systems in mission‑critical or industrial environments (data centers, oil & gas, healthcare, manufacturing, military, etc.)
- Exposure to commissioning activities from an operations, validation, or oversight perspective (ownership not required)
- Working knowledge of mechanical cooling systems such as chillers, cooling towers, CRAH/CRAC units, and heat‑rejection systems
- Ability to work independently in a remote, highly autonomous environment
- Must be able to travel up to 50%, including week‑long site visits
- Familiarity with ASHRAE TC 9.9 thermal guidelines as an operational reference
- Experience working with operational tools such as CMMS, DCIM/BMS, or participating in incident response or RCA processes
- Experience performing system audits, inspections, or readiness assessments
- Data center experience (not required)
