Job Title: Junior / Mid-Level Automation Engineer for Air Separation Unit (Industrial Gases)

Location: Agbara, Ogun

Employment Type: Full-time

Job Summary

• We are seeking to engage an Automation Engineerat the Air Separation Unit of its Industrial Gases plant.
• The automation engineer will design, program, and maintain the industrial control systems that supervise the cryogenic separation of atmospheric air into high-purity oxygen, nitrogen, carbon dioxide and argon

Key Responsibilities

• DCS and PLC Programming: Develop and configure control logic using platforms like Siemens PCS7, TIA Portal, or Allen-Bradley ControlLogix

• SCADA and HMI Management: Build operator interface screens, trend analysis tools, and multi-user server-client architectures in systems like WinCC or Yokogawa CENTUM VP

• Process Automation & Sequences: Program automated start-up, shut-down, deriming (thawing/moisture removal), and molecular sieve purification sequences

• Loop & Interlock Control: Monitor and tune PID loops for critical process parameters including pressure, cryogenic temperatures, flow rates, liquid levels, and turbine speeds

• Functional Safety (SIL/HAZOP): Participate in hazard and operability studies and implement Emergency Shutdown Systems (ESD) to safely handle cryogenic fluids and high-pressure oxygen

• Industrial Networking & Commissioning: Configure field communication protocols (Profibus, Profinet, Modbus, OPC) and execute Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), and plant commissioning.

• Qualification & Experience

• OND/HND/B.Sc/B.Eng in Automation Engineering, Instrumentation & Control (I&C), Electrical Engineering, or Chemical/Process Engineering with a strong control systems focus.

• Professional Certifications (Highly Valued):

• Functional Safety Engineer (TÜV Rheinland / Exida): Essential for designing Safety Instrumented Systems (SIS) used to manage hazardous oxygen and hydrogen risks.

• Professional Engineer (PE / Ch.Eng): Often required for senior roles signing off on safety interlocks and plant design

Junior / Mid-Level (2–5 Years Experience):

• PLC/DCS Maintenance: Hands-on experience troubleshooting logic faults on active plant platforms (e.g., Siemens PCS7/TIA Portal, Yokogawa CENTUM VP, or Emerson DeltaV).
• Field Instrumentation: Calibration and troubleshooting of field devices unique to gas production:
• Cryogenic control valves (managing thermal contraction).
• Online Process Analyzers (paramagnetic oxygen sensors, gas chromatographs, moisture/dew point meters) to ensure product purity.
• Industrial Networks: Configuring and troubleshooting fieldbus networks like Profibus-DP/PA, Profinet, or Modbus TCP connecting field instruments to the control room.
