Mechanical Commissioning Project Engineer

Overview

The Mechanical Commissioning Project Engineer plans mechanical commissioning readiness, coordinates quality inspections, and oversees test execution for integrated facility performance.

What you'll do

• Develop and maintain the mechanical commissioning scope, readiness criteria, inspection strategy, and discipline test execution plan.
• Review mechanical design packages and documentation for commissionability and commissioning risk.
• Coordinate mechanical QA/QC inspections, deficiency capture, and closeout tracking with contractors and vendors.
• Own procedure development and review for equipment startup, functional testing, controls verification, and integrated systems testing inputs.
• Coordinate equipment vendor acceptance requirements, startup support, prerequisites, documentation packages, and vendor participation.
• Lead mechanical review of test results, deficiencies, corrective actions, retest requirements, trend logs, and acceptance evidence.
• Maintain commissioning dashboards and support turnover by confirming documentation, as-builts, test records, and issue disposition are complete.

What you'll need

• 8+ years of mechanical commissioning, mechanical construction, field engineering, startup, testing, balancing coordination, controls verification, or owner representative experience on complex technical infrastructure projects.
• Strong knowledge of mechanical system startup and functional performance testing, including controls interfaces and 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, vendors, QA/QC teams, commissioning partners, and project leadership.
• Practical judgment around readiness, safety, sequencing, test prerequisites, performance validation, and risk escalation.
• Comfort working in construction environments with evolving schedules and parallel work fronts.
• Clear technical writing skills for maintaining logs, test evidence, issue records, and decision history.
