• Design and review control system concepts; support development and implementation of new systems.
• Maintain, modify, and troubleshoot control systems across hardware and software platforms.
• Collaborate with internal stakeholders (engineering, operations, purchasing, sales/marketing) to support project execution.
• Interface with clients, suppliers, contractors, PMs, and authorities in cost- and schedule-driven environments.
• Provide technical oversight for vendor selection, bid evaluations, and supplier performance.
• Ensure compliance with applicable H&S regulations and quality standards.
• Develop and review control system specifications and RFQs.
• Configure Mitsubishi Control System HMI and databases.
• Execute control panel design, documentation, fabrication support, and standards compliance with limited supervision.
• Develop, test, and troubleshoot control logic and HMI applications.
• Support manufacturing activities, including inspections and FATs.
• Resolve customer comments on drawings and documentation.
• Support Field Operations with installation, integration, commissioning, and troubleshooting; perform RCA and implement solutions.
• Prepare and submit accurate technical and field reports.
• Deliver classroom and OJT training on Mitsubishi Control Systems.
• Travel overnight (~10%) by land and/or air.
• Perform other duties as required.

Requirements

• BS in Engineering with 6+ years related experience in control disciplines such as APC, DCS, PLC, OPC/Modbus, and SCADA for power plant applications.
• Strong working knowledge of industrial networking (TCP/IP, subnets, managed switches, firewalls, VLANs, segmentation) with ability to configure and troubleshoot control networks independently.
• Hands-on experience with DCS/PLC platforms (e.g., DIASYS Netmation, Ovation, DeltaV, ABB 800xA, Siemens T3000, or equivalent), including configuration, testing, and troubleshooting.
• Practical experience with Modbus (RTU/TCP), OPC DA/UA, and time sync protocols (NTP/PTP).
• Participation in FAT and SAT, including test execution, documentation, and issue resolution.
• Ability to read and apply electrical and control schematics (power, control, I/O) for troubleshooting and design validation.
• Familiarity with applicable codes and standards: UL 508A, NFPA 70/79, CSA C22.2 / SPE-1000, IEC 60204-1, NEMA.
• Experience with control system and panel design, including equipment selection, layout, I/O assignment, wiring, grounding, and industrial power distribution.
• Working knowledge of electrical design tools such as EPLAN (Electric P8/Pro Panel), AutoCAD Electrical, SOLIDWORKS Electrical, or equivalent.
• Understanding of power plant processes, including gas turbine and combined cycle operations.
• Experience implementing and troubleshooting control logic for Gas Turbine, Combined Cycle, and BOP systems, using FBD, analog loops, and digital controls.
• Ability to develop and interpret control narratives, SAMA diagrams, Cause & Effect matrices, and interlock logic.
• Familiarity with version control, change management, and documentation of logic changes.
• Experience with HMI development and awareness of ISA-101 High-Performance HMI concepts.
• Exposure to alarm management principles (ISA-18.2).
• Awareness of ICS cybersecurity standards including NERC CIP and IEC 62443.
