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.

Maintenance Engineer

The title denotes a recognized engineering role focused on maintenance of servo drives; 'Servo Drive' is a product-specific modifier, but the core professional role is 'Maintenance Engineer', a widely accepted title in industrial electrical engineering. Evidence from LinkedIn job postings confirms its usage for professionals performing fault diagnosis, root cause analysis, and corrective maintenance on servo drive systems.

Engineer

Instrumentation Technician

Sensor Technician is a widely recognized occupational title in industrial automation, particularly within instrumentation and control systems. While 'Sensor Technician' explicitly references the product (sensors), it maps directly to the standardized role 'Instrumentation Technician'—a core profession in process and automation engineering that specializes in calibration, maintenance, diagnostics, and integration of field devices including proximity, temperature, and pressure sensors. Evidence from Glassdoor job postings confirms responsibilities aligned with sensor lifecycle support in automation contexts.

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.
