Job Purpose
The Instrumentation & Control Engineer designs, maintains, and optimizes industrial control systems (DCS, PLC, SCADA) and field instrumentation to ensure safe, efficient, and automated process operations. The role integrates electrical, electronic, and software engineering to monitor and control critical parameters (pressure, temperature, flow) in hazardous environments. Key Responsibilities
1. Control System Design & Implementation

• Design P&IDs, loop diagrams, and control narratives for process plants.
• Configure DCS (Distributed Control Systems) like Honeywell Experion/Yokogawa Centum VP.
• Program PLCs (Siemens S7, Allen-Bradley, Schneider) for automated processes.

2. Instrumentation Engineering

• Specify and calibrate field instruments:
  • Flowmeters (Coriolis, Ultrasonic)
  • Control Valves (Fisher, Masoneilan)
  • Analyzers (pH, gas chromatographs)
• Implement SIL (Safety Integrity Level) systems per IEC 61511.

3. System Integration & Troubleshooting

• Integrate SCADA systems (Ignition, WinCC, iFix) with PLCs/DCS.
• Diagnose 4-20mA/HART/Foundation Fieldbus communication faults.
• Conduct loop checks and FAT/SAT (Factory/Site Acceptance Tests).

4. Safety & Compliance

• Ensure compliance with SANS 10108 (Explosive Atmospheres) and IEC 60079 (ATEX).
• Perform HAZOP/LOPA studies for control system safety.
• Maintain calibration records for ISO 9001 audits.

5. Project Execution

• Manage control system upgrades (migration from legacy to modern DCS).
• Supervise E&I contractors during plant shutdowns.
• Optimize PID tuning for process efficiency.

Required Qualifications

• BEng/BTech in Electrical/Electronic/Mechatronic Engineering.
• Professional Registration: ECSA PrEng/PrTechEng (advantageous).
• Certifications:
  • SIL Certification (TÜV Rheinland).
  • HART/Fieldbus Commissioning.
  • Project Management (PMP/PRINCE2).

Essential Skills & Competencies
Technical Skills

• Control Systems:
  • DCS/PLC programming (STL, FBD, SFC).
  • OPC UA/DA communication protocols.
• Instrumentation:
  • Calibration standards (ISO 17025).
  • Intrinsic safety (Ex d/e/i).
• Software Tools:
  • AutoCAD Electrical / EPLAN (for schematics).
  • MATLAB/Simulink for control algorithm simulation.

Soft Skills

• Analytical troubleshooting of complex control loops.
• Interdisciplinary coordination with process/mechanical teams.
• Technical report writing for compliance documentation.

Experience Requirements

• 5+ years in process industries (refineries, power plants, mines).
• Hands-on Experience With:
  • ESD (Emergency Shutdown Systems).
  • VFD (Variable Frequency Drive) integration.
  • Wireless instrumentation (ISA100/WirelessHART).
• Industry Exposure:
  • Sasol/Engen/Medupi power plant projects.
  • Mining process control (smelters, concentrators).
