• Troubleshoot DCS hardware, software, networking, communications, and system integration issues.
• Lead DCS configuration changes, control strategy modifications, graphics development, upgrades, and lifecycle improvements.
• Support the refinery’s migration from Honeywell TDC-3000 to Emerson DeltaV.
• Troubleshoot integration between DCS, PLCs, SIS, analyzers, historians, packaged equipment, and other industrial systems.
• Support refinery OT infrastructure, including servers, workstations, industrial networks, firewalls, virtualization, and backups.
• Apply industrial cybersecurity and defense-in-depth practices to control system environments.
• Lead or support capital projects, shutdowns, system upgrades, FATs, SATs, commissioning, and startup activities.
• Provide technical direction to vendors, contractors, technicians, and engineers.
• Develop system standards, documentation, backup strategies, disaster recovery procedures, and lifecycle plans.

What We’re Looking For

• 3+ years of Honeywell TDC-3000 architecture, configuration, maintenance, and troubleshooting experience.
• Experience supporting DCS platforms in a refinery, petrochemical, chemical, or other continuous-process manufacturing environment.
• Ability to independently troubleshoot complex DCS hardware, software, networking, communications, and integration problems.
• Understanding of PLC architecture, I/O, communications, and DCS/PLC integration.
• Knowledge of industrial communication protocols such as Modbus, Modbus TCP, OPC, Ethernet/IP, and serial communications.
• Experience with industrial Ethernet, managed switches, VLANs, TCP/IP, firewalls, and Process Control Networks (PCN).
• Knowledge of Windows Server, Active Directory, virtualization, backups, recovery, patching, and OT infrastructure.
• Understanding of industrial cybersecurity within process control environments.
• Ability to interpret P&IDs, loop drawings, wiring diagrams, logic diagrams, cause-and-effect documentation, and network diagrams.
• Bachelor’s degree in Chemical Engineering, Electrical Engineering, Computer Engineering, Computer Science, IT, Electronics, or a related technical field preferred. Equivalent experience will be considered.

Preferred Experience

• Emerson DeltaV experience.
• Triconex Safety Instrumented Systems (SIS) experience.
• Alarm management and abnormal situation management.
• Control loop performance and process control optimization.
• Refinery PSM, MOC, and formal engineering change processes.
• Experience leading DCS modernization or migration projects.
• Experience with FAT, SAT, commissioning, startup, and field implementation.

Why Consider This Opportunity?

You’ll have the opportunity to own critical control system infrastructure, influence long-term automation strategy, and help shape a refinery’s transition from a legacy DCS to a modern Emerson DeltaV platform. The role combines process control engineering, OT infrastructure, cybersecurity, project leadership, and hands-on troubleshooting.
