Essential Duties and Responsibilities

• Design, develop, test, and maintain PLC and HMI applications for gas-processing and urea systems.
• Troubleshoot control logic, instrumentation, industrial communications, and control hardware to identify and resolve production issues.
• Develop and maintain pressure, temperature, flow, and level control strategies, including PID loops, operating sequences, alarms, permissives, and interlocks.
• Work with Operations and other engineering disciplines to define operating requirements and evaluate proposed control changes.
• Standardize control programs across equipment variations while maintaining configuration management, version control, and backups.
• Plan, document, and test control-system changes through applicable management-of-change procedures.
• Perform factory and site acceptance testing, commissioning, and verification of control and shutdown functions.
• Develop and maintain control narratives, cause-and-effect documentation, I/O lists, communication maps, and troubleshooting procedures.
• Support Ignition HMI development, integration, deployment, and troubleshooting.
• Provide technical support and training to Operations, maintenance personnel, and other engineering teams.
• Participate in project planning, equipment evaluations, and continuous improvement efforts.

Other Requirements:

• A bachelor’s degree or higher in Chemical Engineering, Electrical Engineering, Petroleum Engineering, Computer Science, or an equivalent engineering discipline, plus at least three years of PLC, DCS, or HMI programming experience; or at least six years of PLC, DCS, or HMI programming experience in lieu of the degree requirement.
• Ability to travel ~35%
• Working knowledge of industrial control programming methods, such as ladder logic, structured text, or function block programming.
• Ability to read and interpret P&IDs, electrical schematics, wiring diagrams, and control-system documentation.
• Understanding of process instrumentation, analog and discrete I/O, PID control, alarms, and interlocks.
• Strong troubleshooting skills and the ability to communicate technical findings clearly.
• Excellent written and verbal communication skills.
• Availability to participate in an on-call rotation and provide after-hours troubleshooting support.
• Valid driver’s license and ability to travel to operating sites, with estimated travel of 35%.

Preferred Qualifications

• Experience programming Allen-Bradley PLCs using Studio 5000 or RSLogix 5000 is strongly preferred. 
• Experience in gas processing, oil and gas, oil-refining, or petrochemical operations is strongly preferred. 
• Experience troubleshooting industrial electrical and control circuits operating at 24 VDC, 110 VAC, 480 VAC, or comparable voltage levels.
• Experience with gas heaters, pressure regulators, control valves, and Coriolis flowmeters.
• Experience with urea storage, pumping, transfer, or dosing controls.
• Experience with Ignition, FactoryTalk View, and/or VTScada HMI systems.
• Experience integrating industrial devices through EtherNet/IP, Modbus TCP, and Modbus RTU.
• Experience troubleshooting remote I/O, industrial Ethernet networks, serial communications, and instrumentation.
• Experience with control-system standardization, software version control, commissioning, and management of change.
• Familiarity with process safety, shutdown systems, and applicable industrial electrical and instrumentation standards.
