This position reports to a senior leadership executive.

Key Responsibilities

• Lead all aspects of mechanical engineering, including basis of design, scopes of work, implementation plans, and commissioning strategies.

• Ensure ongoing availability and reliability of mechanical systems across all sites, including HVAC, chilled water systems, and other critical cooling infrastructure.

• Approve and oversee upgrades that increase capacity, reliability, and energy efficiency.

• Maintain and update all as-built documentation and master mechanical system records.

• Perform field inspections to identify and resolve discrepancies between system design and actual installation.

• Develop, implement, and manage maintenance programs to ensure system health and efficiency.

• Create and review detailed maintenance procedures, including annual service schedules.

• Support operational teams in troubleshooting, root cause analysis, and system performance reviews.

• Provide immediate technical expertise during critical system events and participate in an on-call rotation.

• Manage vendor relationships and mechanical service contracts to ensure compliance and performance.

• Maintain all system documentation, schematics, and process records.

• Drive improvements in energy usage, system reliability, and mechanical performance.

• Provide estimates for time and materials needed for projects and repairs.

• Occasional travel to data center sites may be required.
