Automation Engineer for Air Separation Unit (Industrial Gases) - Senior Level

Automation Engineer for Air Separation Unit (Industrial Gases) - Senior Level

Location: Agbara, Ogun

Employment Type: Full-time

Job Description

• We are seeking to engage an Automation Engineer at the Air Separation Unit of our 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.

• Qualifications & 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

Senior Level (6+ Years Experience):

• Greenfield/Brownfield Commissioning: Leading the control system execution from loop checks to initial plant start-up, including automated Molecular Sieve (Pre-Purification Unit) switching sequences.
• Advanced Process Control (APC): Designing loop interactions to optimize energy consumption. Since air separation is highly power-intensive, seniors program algorithms for compressor guide-vane control and anti-surge protection.
• Safety System Design: Experience configuring Emergency Shutdown Systems (ESD) with high Safety Integrity Levels (SIL 2/3) to prevent catastrophic over-pressurization or oxygen-enriched fires.
