Instrumentation & Control Technician

Job Summary: The Industrial Instrumentation & Controls (I&C) Technician installs, maintains, calibrates, commissions, and troubleshoots instrumentation, control systems, and associated electrical and electronic equipment at heavy industrial customer facilities. This is a journeymen-level field role requiring the ability to work independently, interpret technical documentation, diagnose complex process-control problems, and complete work safely and professionally in active operating environments. The technician may support new construction, maintenance, shutdowns, turnarounds, system upgrades, commissioning, and emergency troubleshooting assignments. Key Responsibilities: Install, inspect, maintain, repair, calibrate, and troubleshoot instruments that measure and control process variables, including pressure, flow, level, temperature, analytical properties, vibration, speed, position, motion, force, and other operating conditions. Install and service transmitters, switches, transducers, sensors, analyzers, gauges, control valves, actuators, positioners, solenoids, limit switches, junction boxes, marshalling panels, remote I/O, control panels, instrument tubing, and associated cabling and terminations. Read and interpret P&IDs, instrument loop diagrams, hook-up drawings, wiring diagrams, schematics, control narratives, cause-and-effect documents, logic diagrams, ladder logic, I/O lists, equipment data sheets, vendor manuals, and installation specifications. Configure, range, test, and calibrate smart and conventional field instruments using handheld communicators, vendor software, and appropriate precision test equipment. Perform point-to-point checks, continuity checks, loop checks, functional testing, alarm and trip verification, control-valve stroking, interlock testing, and commissioning or startup support. Troubleshoot complete control loops and identify faults in field devices, wiring, power supplies, PLC/DCS I/O, control panels, communication networks, software configuration, and final control elements. Use multimeters, process calibrators, milliamp sources, pressure pumps, manometers, deadweight testers, temperature simulators, insulation testers, tachometers, HART communicators, and other diagnostic or precision instruments. Support PLC, DCS, HMI, SCADA, historian, remote I/O, and industrial communication systems within the technician's training and authorization; coordinate programming or configuration changes with controls engineers or authorized programmers. Disassemble malfunctioning instruments, evaluate mechanical and electronic components, repair or replace defective parts, reassemble equipment, and verify conformance with manufacturer and project specifications. Perform preventive and predictive maintenance; identify developing equipment issues and recommend corrective actions or reliability improvements. Maintain accurate calibration records, inspection reports, test documentation, redlines, as-built…
