• Configure and troubleshoot industrial networks and communication protocols (Ether Net/IP, Modbus TCP/RTU, Device Net, OPC), and integrate PLCs with instrumentation, VFDs, motor control centers, analyzers, and third-party skid packages.
• Tune PID control loops, migrate legacy control systems to current platforms with minimal disruption to operations, and diagnose complex control system problems in the field and remotely.
• Manage program backups, version control, change management, and cybersecurity and access practices for all control system code.
• Review and mark up electrical drawings, loop diagrams, P&IDs, and control panel layouts; specify PLC hardware, I/O, and network components, prepare cost and time estimates, and review vendor, integrator, and contractor work for quality and standards compliance.
• Train and mentor I&E Technicians and Operations personnel on control system operation and troubleshooting, and provide controls support during plant outages.

• Technical degree, High School Diploma or equivalent required.
• 10+ years of hands-on PLC programming experience in an industrial process environment.

• Proven ability to independently design, program, and commission control systems with minimal supervision.
• Strong working knowledge of HMI/SCADA development, industrial networking, and instrumentation, including the ability to read electrical schematics, P&IDs, and loop drawings.
