Reporting to a Senior Commissioning Engineer, you will be trusted to operate autonomously on-site — managing testing, troubleshooting, and documentation while maintaining the highest standards of safety and quality.  This is a high-travel, hands-on field role. You will spend the majority of your time on project sites across the U.S. and occasionally internationally. The ideal candidate is technically sharp, highly organized, and comfortable leading a small team in fast-paced construction environments.  Key Responsibilities  <span data-ccp-parastyle="heading 30"
