This role works closely with clients, contractors, vendors, engineers, commissioning teams, and operations personnel to identify risks, resolve technical challenges, and drive projects toward successful completion.

Responsibilities

Serve as the mechanical subject matter expert for quality and commissioning activities within mission-critical facilities.
Provide technical leadership across the project lifecycle, including construction, mechanical installation, quality assurance, commissioning, startup, and handover.
Assess mechanical systems and associated infrastructure, including chillers, cooling towers, CRAH/CRAC units, air handlers, pumps, hydronic and condenser water systems, liquid cooling and CDUs, fuel systems, plumbing, and fire protection, to quickly understand how systems operate, interact, fail, and recover.
Apply expert knowledge of mechanical systems and associated infrastructure to support project execution, quality, commissioning, and operational readiness.
Evaluate system operation, control philosophies, redundancy, failure modes, and sequences of operation, including BMS/BAS integration, to identify technical risks and deficiencies.
Review and interpret P&IDs, mechanical flow diagrams, control schematics, equipment submittals, construction drawings, and technical specifications.
Apply applicable mechanical codes, standards (including ASHRAE, IMC, NFPA, and ASME), project specifications, and industry best practices throughout construction, installation, commissioning, and turnover activities.
Identify technical risks, deficiencies, and potential system issues and develop practical solutions to address them.
Troubleshoot complex mechanical system issues, perform root cause analysis, and determine appropriate corrective actions.
Data-mine drawings, specifications, vendor documentation, historical records, commissioning data, TAB reports, and other available information to identify and resolve technical challenges.
Plan, schedule, coordinate, and lead mechanical commissioning, flushing and cleaning, pressure testing, startup, functional testing, integrated systems testing, and turnover activities.
Provide technical direction and oversight to field teams, contractors, vendors, and other project stakeholders.
Coordinate multiple teams throughout project execution while maintaining focus on safety, quality, schedule, and successful system delivery.
Support the identification, tracking, resolution, and closure of technical issues and deficiencies.
Communicate technical findings, risks, recommendations, and solutions effectively with clients, contractors, vendors, engineers, and operations teams.
Support successful system handover by ensuring mechanical systems are properly tested, balanced, documented, and prepared for operational use.
Demonstrate ownership of technical challenges and drive issues through to successful resolution.
