Protection Engineer

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.

Field Service Technician

Field Service Technician is a widely recognized professional role in industrial automation, specifically tasked with on-site deployment, commissioning, diagnostics, preventive/predictive maintenance, and repair of motor drives including VFDs. The role is standardized across OEMs (e.g., ABB, Danfoss, Siemens) and aligns directly with the product context of variable frequency drives used for motor speed/torque control. While specialization in drives may exist, 'Field Service Technician' itself is not product-specific — it's a canonical, cross-domain role.

Protection Technician

The term denotes a technician specializing in protection systems for motors, with documented field responsibilities (testing, calibration, fault diagnosis, maintenance) aligned with industrial motor protection relays. While 'Motor Protection Relay Technician' is product-specific, the canonical professional role is 'Protection Technician' — a recognized subcategory of electrical technicians focused on protective relay systems. This aligns with industry standards (e.g., IEEE C37 series, NFPA 70E) and job postings emphasizing relay testing, coordination studies support, and arc-flash mitigation roles.
