What does an instrument and controls engineer do?

An Instrument and Controls Engineer is responsible for designing, developing, installing, and maintaining the systems that monitor and control engineering processes. These engineers ensure that instruments—such as sensors, valves, and controllers—function correctly to maintain safety, efficiency, and reliability in industrial settings like power plants, oil refineries, and manufacturing facilities. They also troubleshoot equipment issues, optimize system performance, and work closely with other engineering disciplines to support plant operations. Their work helps automate processes and ensures compliance with industry standards and regulations.
