Day 1 on the Process Control Engineer path.

What a Process Control Engineer does

Keeps industrial processes running safely and consistently by designing and tuning control systems, sensors, and alarms for plants and production lines.

  • Design control strategies to keep temperature, pressure, flow, and level within limits
  • Configure and test PLC and DCS logic, alarms, and interlocks
  • Tune PID loops and troubleshoot unstable or slow process behavior
  • Select sensors and control valves and define instrument ranges and locations
  • Review process data and trends to find root causes and improve performance
  • Write control narratives, test plans, and operating procedures for changes
  • Coordinate with operations, maintenance, and safety teams during upgrades
  • Support commissioning and start-ups, including on-site testing and handover

A day in the life

  1. Check overnight alarms and trends, then prioritize issues with operations
  2. Work on a control change, simulate or test it, and review risks with safety
  3. Go to the plant to verify instruments, wiring, and valve behavior
  4. Meet with process and electrical engineers to align on upcoming projects
  5. Document changes and update loop sheets, drawings, and alarm settings
