Technician

Technician is a widely recognized professional role in HVAC engineering, explicitly referenced in ASHRAE guidance for cooling tower systems. While generic, it denotes a credentialed, hands-on technical role responsible for installation, commissioning, operation, inspection, maintenance, troubleshooting, and testing of HVAC equipment including cooling towers. It is not product-specific (e.g., no 'Cooling Tower Technician' prefix), so product_specific_title = false. The role is distinct from engineers or operators and falls under the Maintenance family with broad technical execution responsibilities.

Environmental Engineer

Environmental Engineer is a widely recognized professional engineering role. In the acoustics domain—particularly for sound level meters—the role conducts noise surveys using such instruments, evaluates noise exposure, specifies appropriate measurement equipment (e.g., Class 1 vs. Class 2 SLMs), interprets acoustic data for compliance, and may specify or validate test protocols. The evidence explicitly links this role to conducting noise surveys with calibrated sound level meters and ensuring regulatory compliance (NIOSH/OSHA), confirming direct functional relationships to selection, specification, testing, and inspection of the product.
