Maintenance Technician

Mechanical Engineer

Facilities Mechanical Engineer is a widely recognized professional role in building services and HVAC engineering, focused on the design, operation, maintenance, and optimization of mechanical systems—including chillers—in commercial and industrial facilities. While 'Facilities' denotes a domain specialization (not product-specific), it does not make the title product-specific (e.g., not 'Chiller Mechanical Engineer'). The role is distinct from generic Mechanical Engineer due to its consistent association with facility infrastructure, lifecycle management, and integrated HVAC system oversight. Evidence from job boards (Indeed) confirms real-world usage with explicit chiller-related responsibilities.

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.

Process Engineer

Beverage Process Engineer is a recognized engineering role specializing in process design, validation, and compliance for beverage manufacturing systems. While 'Beverage' denotes industry context (not product-specific specialization), the role directly engages with ribbon blenders — particularly in specification, commissioning (including IQ/OQ), CIP/SIP integration, and 3-A sanitary validation — all cited in job listings. 'Process Engineer' is the canonical, general professional title; 'Beverage' reflects domain application, not an inseparable part of the core role definition.

Engineer

Plant Technician

Chemical plant technician is a widely recognized operational role in process industries; while 'chemical plant' denotes industry context, the core role is Plant Technician — a standard occupational title. Evidence confirms technicians perform valve maintenance (including gate valves), fluid system troubleshooting, and preventive maintenance, directly relating to inspection, maintenance, troubleshooting, and operation of industrial valves.
