We re specifically interested in hearing from candidates with strong data center experience, so if this is your area of expertise, we d love to connect.

If you re ready to take the next step in your career, we d love to hear from you.

The Role:

The CX Mechanical Engineer is responsible for the planning, execution, and management of commissioning activities for mission-critical mechanical systems within hyperscale data center environments. This role ensures that all mechanical and thermal infrastructure is installed, tested, integrated, and handed over in full compliance with project requirements, safety standards, and operational objectives, supporting high-availability and energy-efficient operations.

The responsibilities for this role include, but are not limited to, the following:

Commissioning Management

• Lead and manage the end-to-end commissioning process for mechanical systems, from pre-functional testing through integrated systems testing (IST) and final handover.
• Ensure commissioning activities are executed in accordance with approved commissioning plans, project schedules and quality standards.
• Coordinate phased and systems-based commissioning strategies typical of hyperscale delivery model

Mechanical Systems Testing Validation

Commission and validate critical mechanical infrastructure, including but not limited to:

• Chilled water systems (chillers, pumps, cooling towers, heat exchangers)
• Airside systems (CRAC/PAHUs, AHUs, FWUs)
• Direct-to-chip, liquid cooling, or hybrid cooling systems (where applicable)
• HVAC distribution systems (ductwork, piping, valves, dampers)
• Fuel oil and lube oil systems supporting standby generation
• Make-up water, water treatment, and blowdown systems
• Verify system performance under normal, abnormal, and failure conditions.
• Validate thermal performance, capacity, control response, and efficiency against design intent and client requirements.

Project Coordination Oversight

• Plan, coordinate and lead mechanical commissioning activities in collaboration with design engineers, construction teams, vendors, controls specialists and operations stakeholders.
• Act as the primary technical authority for mechanical commissioning issues on site.
• Support construction readiness, system turnover and commissioning sequencing in fast-track hyperscale environments.

Mechanical Controls Integration

• Ensure seamless integration of mechanical systems with:
  • Electrical power systems
  • Controls, BMS, and EPMS
  • Fire/life safety systems
  • IT load and white-space requirements
• Validate system redundancy (N, N+1, 2N), fault tolerance, and maintainability to support mission-critical operations.
• Lead functional performance testing and integrated systems testing involving mechanical failure scenarios.

Documentation Reporting

Develop and manage commissioning documentation, including:

• Commissioning plans and schedules
• Mechanical test procedures and functional performance scripts
• Method statements and risk assessments
• Final commissioning reports, as-built records and handover documentation
• Provide clear, accurate progress, risk and readiness reports to project and client stakeholders.

Standards Compliance

• Ensure all mechanical systems and commissioning activities comply with applicable codes, standards and best practices, including:
  • ASHRAE (including TC 9.9)
  • CIBSE, SMACNA, IPC
  • IEC, ISO, and local authority requirements
  • Uptime Institute Tier Standards
  • TIA-942 and client-specific hyperscale standards
• Support third-party audits, peer reviews and certifications where required.

Factory Site Acceptance Testing (FAT SAT)

• Plan, coordinate and lead FAT and SAT activities for mechanical equipment and packaged systems.
• Review vendor submittals, test data and corrective actions to ensure equipment readiness for site installation and integration.
• Witness performance testing of major plant (chillers, PAHUs, cooling towers, packaged plant).

Risk Management Troubleshooting

• Identify technical, schedule, operational and safety risks related to mechanical commissioning.
• Implement mitigation strategies and lead root-cause analysis and troubleshooting to resolve issues efficiently.
• Support rapid issue resolution in live or partially energized data hall environments.

Health, Safety Environmental Compliance

• Demonstrate a strong understanding of mechanical and process safety, particularly when working with:
  • Pressurized systems
  • Rotating equipment
  • Chemical treatment systems
  • Live data center environments
• Ensure all commissioning activities comply with health and safety regulations, permit-to-work systems, confined space requirements and lock-out/tag-out (LOTO) procedures.
• Promote and enforce a strong safety culture across all commissioning activities.

Leadership Team Development

• Lead and support contractors, and subcontractors.
• Provide technical guidance, training and oversight to ensure consistent commissioning quality and hyperscale delivery standards.
• Interface effectively with client operations teams to ensure a smooth transition to steady-state operations.

Continuous Improvement

• Adhere to company policies, procedures and quality management systems.
• Capture lessons learned and promote continuous improvement in commissioning methodologies, energy performance and reliability outcomes across hyperscale data center projects. Qualifications
