Supervisory Control and Data Acquisition (SCADA) systems help monitor and control operations and processes. As a SCADA engineer, your duties focus on designing, configuring, and deploying these systems in a manufacturing or other industrial environment. You configure existing systems and plan the deployment of devices, computers, and instruments that are a part of the SCADA system. A developer also performs maintenance and handles update responsibilities for software and hardware within the system. Engineers develop procedures for emergencies and help troubleshoot when issues arise. In most positions, you also analyze system performance and suggest or make improvements where applicable.
