Engineer III, Control Systems

Mitsubishi Heavy Industries, Ltd.•Lake Mary, FL

About The Position

The Control Systems Engineer III develops engineering designs, performs engineering reviews, and configures, tests, and troubleshoots control systems for Mitsubishi Power projects in the Americas. The role works with limited supervision to meet code, contract, and schedule requirements, contribute to design improvements, and provide effective technical solutions across projects. It primarily supports control systems for large-frame industrial gas turbines operating in simple-cycle and/or combined-cycle configurations with steam turbines; the scope may also include other plant control systems. The position also provides customer training and remote and on-site technical support. Responsibilities span control system design and documentation, vendor and manufacturing support, factory testing, field installation and integration, commissioning, operations support, and troubleshooting. Overnight travel by land and/or air is required at least 10% of the time.

Working knowledge and practical application of industrial communication protocols, including Modbus RTU/TCP, OPC DA/UA, and NTP/PTP time synchronization in control environments.
Experience participating in FAT and Site Acceptance Testing (SAT), including executing test procedures, documenting results, and supporting issue resolution.
Ability to accurately read and interpret electrical and control system schematics, identify device functions and signal flow across multi-sheet drawings, and apply standards to troubleshooting and design validation.
Familiarity with U.S. and international codes and standards such as UL 508A, NFPA 70, NFPA 79, CSA C22.2 / SPE-1000, IEC 60204-1, and NEMA, with the ability to apply them in routine design activities.
Experience with control system and panel design tasks, including equipment selection, panel layout, and I/O assignment, and 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 the ability to develop and modify design deliverables.
Practical understanding of power plant processes, including gas turbine and combined-cycle operations, 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 the 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 change traceability.
Experience with HMI graphic creation tools and familiarity with High-Performance HMI concepts per ISA-101, with the ability to develop standard operator displays.
Exposure to alarm management concepts and familiarity with ISA-18.2 principles.
