Instrumentation and Automation Control System Technician

Instrumentation and Automation Control System Technician

Job Summary

Responsible for the installation, maintenance, troubleshooting, and loop checking of field instruments and automation control system equipment in industrial environments. This combined role covers both process measurement (pressure, temperature, flow, level) and control system hardware (PLC, DCS, SCADA, HMI, panel wiring, I/O testing). The role operates across site field activities, automation panels, and control logic, requiring proficiency in both instrumentation and electrical automation disciplines.

• Install, maintain, calibrate, and troubleshoot field instruments including transmitters, sensors, pressure gauges, temperature elements, flow meters, and level devices.
• Perform loop checking, wiring, cable termination, ferruling, labeling, and signal testing on instrumentation circuits.
• Install, maintain, and troubleshoot automation and control system equipment including PLCs, DCS panels, HMI units, RTUs, and I/O modules.
• Execute panel wiring, I/O verification, logic checks, and system diagnostics on control system hardware.
• Perform preventive and corrective maintenance in accordance with OEM manuals, site procedures, and the permit-to-work (PTW) system.
• Support commissioning, pre-commissioning, shutdown, and turnaround activities.
• Read and interpret instrument loop diagrams, P&IDs, electrical schematics, and control logic drawings.
• Maintain calibration records, loop check sheets, and maintenance logs in the ERP/CMMS system.
• Coordinate with operations, engineering, and HSE teams to maintain plant reliability and safety.
• Ensure compliance with applicable international standards (IEC, ISA) and client HSE requirements at all times.

• Diploma or degree in Instrumentation, Electrical Engineering, Electronics, Automation, or Mechatronics.
• Minimum 2 years of experience in instrumentation and/or control system maintenance in an industrial environment.
• Experience in oil and gas, petrochemical, utilities, or similar industrial sectors is preferred.
• Familiarity with hazardous area classifications and compliance with HSE standards.
• Valid safety certificates (First Aid, H2S, COSHH, or equivalent) are an advantage.

• Proficiency in HART, Modbus, and Profibus communication protocols.
• Hands-on experience with PLC, DCS, SCADA, and HMI platforms.
• Calibration of process instruments using dry blocks, pressure calibrators, and multimeters.
• Ability to read loop diagrams, P&IDs, and electrical schematics.
• Strong fault-finding and root-cause analysis skills in both field and panel environments.
• Knowledge of industrial safety practices, PTW systems, and LOTO procedures.
• Attention to detail and accurate documentation of maintenance activities.
