The Process Control Engineer is responsible for maintaining, improving, and optimizing process control strategies to support safe, reliable, and efficient operation of chemical manufacturing units. This position serves as the primary technical resource for regulatory control systems, DCS configuration, control loop performance, alarm management, process optimization, and process safety controls.

The role focuses on improving unit performance through effective process control applications, troubleshooting process-related issues, supporting capital and maintenance projects, and collaborating with Operations, Process Engineering, Production, and Instrumentation teams. While familiarity with PLC-based systems is required, the primary emphasis is on chemical process control, DCS systems, and process optimization rather than automation programming.
