• Hands-on experience with Distributed Control Systems (DCS) such as DIASYS Netmation, Ovation, DeltaV, 800xA, T3000, or equivalent PLC/DCS platforms, including independent configuration, testing, and troubleshooting of standard system functions.
• Working knowledge and practical application of industrial communication protocols such as Modbus (RTU/TCP), OPC DA/UA, and time synchronization (NTP/PTP) in control environments.
• Experience participating in Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT), including execution of test procedures, documentation of results, and support of issue resolution.
• Accurately reads and interprets electrical and control system schematics (power, control, and I/O wiring), identifies device functions and signal flow across multi-sheet drawings, and applies standards to support troubleshooting and design validation.
• Familiar with USA/International codes and standards such as UL 508A, NFPA 70, NFPA 79, CSA C22.2 / SPE-1000, IEC 60204-1, and NEMA, with ability to apply them in routine design activities.
• Experience executing control system and panel design tasks, including equipment selection, panel layout, and I/O assignment, with ability to complete standard designs with limited supervision. Working understanding of wiring practices, grounding, and industrial power distribution.
• Working knowledge of electrical design tools such as EPLAN Electric P8, EPLAN Pro Panel, AutoCAD Electrical, SOLIDWORKS Electrical Schematic, or equivalent, with ability to develop and modify design deliverables.
• Practical understanding of power plant processes, including gas turbine and combined cycle operations, with ability to support control strategy implementation and troubleshooting.
• Experience implementing control logic for Gas Turbine, Combined Cycle, and Balance of Plant systems, including analog loops and digital controls using Function Block Diagram, with ability to troubleshoot standard control issues.
• Ability to develop and interpret control narratives, SAMA diagrams, Cause & Effect matrices, and interlock logic with limited guidance.
• Working knowledge of version control and change management practices for control logic, including documentation and traceability of changes.
• Experience with HMI graphic creation tools and familiarity with High-Performance HMI concepts per ISA-101, with ability to develop standard operator displays.
