What you will do

• Develop and maintain mechanical commissioning scope, readiness criteria, inspection strategy, and discipline test execution plan.
• Review mechanical design packages, specifications, submittals, method statements, controls narratives, sequence assumptions, and testing requirements.
• Coordinate mechanical QA/QC inspections with contractors and vendor field/test engineers.
• Own mechanical commissioning procedure development and review.
• Coordinate with equipment vendors on factory/site acceptance requirements, startup support, and test prerequisites.
• Support readiness and execution for cooling, ventilation, hydronic, pumping, heat rejection, controls, and other project-specific mechanical systems.
• Lead discipline-level review of mechanical test results, deficiencies, corrective actions, and retest requirements.
• Maintain mechanical commissioning dashboards and status inputs.
• Partner with the Electrical Commissioning Lead on cross-discipline dependencies.
• Support turnover by confirming mechanical documentation, as-built evidence, and test records are complete.

Required qualifications

• 8+ years of mechanical commissioning, mechanical construction, field engineering, startup, testing, balancing coordination, controls verification, or owner representative experience on complex technic
• Strong knowledge of mechanical system startup, functional performance testing, controls interfaces, cooling or ventilation systems, hydronic systems, and equipment/vendor startup workflows.
• Experience reviewing commissioning specifications, inspection checklists, functional test scripts, vendor startup procedures, test reports, and trend evidence.
• Ability to coordinate field execution across contractors, equipment vendors, QA/QC teams, commissioning partners, and project leadership.
• Strong practical judgment around readiness, safety, sequencing, test prerequisites, performance validation, and risk escalation.
• Comfort working in construction environments with evolving schedules and multiple parallel work fronts.
• Clear technical writing skills and discipline in maintaining logs, test evidence, issue records, and decision history.
• Ability to be present at the project site during critical mechanical installation, startup, controls checkout, functional testing, and integrated testing windows.

Nice to have

• Owner-side or commissioning agent experience on mission-critical, industrial, manufacturing, data center, or other high-reliability facilities.
• Professional engineering, commissioning, controls, balancing, or equivalent field qualification.
• Experience with integrated systems testing and coordination between mechanical, electrical, controls, and operations teams.
• Familiarity with digital issue tracking, commissioning management platforms, schedule tools, trend tools, and field reporting workflows.
• PE license
• Commissioning certification eg. QCxP, CxA, BCxP, CCP
