About The Position

Marathon Petroleum Company’s Illinois Refining Division in Robinson, Illinois, is seeking a Process Controls Engineer. Reporting to the Process Controls Manager, this role designs, implements, and maintains process control strategies to optimize unit performance and reliability. Relocation is approved. The engineer troubleshoots control-system hardware, software, and network issues; works with operations, engineering, OT, and maintenance teams; and supports Management of Change, incident investigations, and root-cause analyses. The role also develops control documentation, supports turnaround planning and execution, and collaborates with project teams to integrate control systems with existing infrastructure. The position applies process-control fundamentals to industrial processes, including process modeling, PID tuning, disturbance-rejection and feedforward strategies, and regulatory-control applications. It also supports advanced process control applications, builds and modifies PI points, and designs and troubleshoots DCS graphics, including integrating controllers, logic, and alarm/status visualization into Honeywell Experion graphics. The position participates in a weekly rotating refinery on-call program for off-hours response when needed. Work schedules may be full in-office, hybrid, or a 9/80 schedule. Additional hours may be required for turnaround and outage support.

Two years of process-controls experience.
Experience with Experion, TDC 3000, C300, C300PM, Triconex, Fuels Manager, and HMI WebDisplay.
Experience with computer communication protocols and configuration.

Responsibilities

Design, implement, and maintain process-control strategies to optimize unit performance and reliability.
Troubleshoot and resolve control-system issues involving hardware, software, and network components.
Collaborate with operations, engineering, OT, and maintenance teams to resolve operational challenges, and develop and maintain relationships with console operators.
Lead or support Management of Change processes for control-system modifications.
Lead incident investigations and root-cause analyses involving control systems.
Develop and maintain control narratives, cause-and-effect diagrams, alarm rationalization, and system architecture drawings.
Assist with planning and executing turnarounds, including scope development and post-event evaluations.
Collaborate with project teams to define control-system scope and ensure integration with existing infrastructure.
Maintain a basic understanding of advanced process control applications to assist or support improvements to process stability and economic performance.
Apply process-control fundamentals to industrial processes, including analyzing process dynamics, developing FOPDT/SOPDT models, calculating and troubleshooting PID tuning, evaluating disturbance rejection and feedforward strategies, and developing calculations for split-range, ratio, cascade, override, and related regulatory-control applications.
Participate in the refinery on-call program, with weekly rotations among process control group members, to provide off-hours response when needed.
Build and modify PI points to facilitate database management and optimize data collection.
Design, implement, and troubleshoot process-control graphics in the DCS environment to maximize operator interface effectiveness, including integrating controllers, control logic, and alarm/status visualization into Honeywell Experion graphics.
