The SCADA/PPC Engineer will be responsible for the development, configuration, integration, testing, commissioning, and troubleshooting of SCADA and Plant Power Control (PPC) systems for utility-scale renewable energy projects, including Solar PV and Battery Energy Storage Systems (BESS).


The position will have a strong hands-on focus on Ignition SCADA, PPC controls, PLC/RTAC integration, industrial communication protocols, HMI development, historian systems, and plant-level monitoring and control. The engineer will work closely with internal teams, equipment vendors, utilities, and customers to implement reliable and standardized SCADA/PPC solutions.


The ideal candidate will have practical experience developing Ignition applications, integrating field devices and controllers, implementing control logic, troubleshooting communications, and supporting FAT, SAT, commissioning, and site troubleshooting activities.


**Attention external recruitment firms, we will not accept any unsolicited resumes at this time. Please do not contact any internal member of our company to discuss the position or to solicit candidates. **
