About The Position

The Controls Engineer III designs, develops, validates, and executes control logic that meets defined control system requirements, performance criteria, and operational objectives for Mitsubishi Power projects in the Americas. The position contributes to design improvements and supports technical solutions across projects. It primarily focuses on control logic for large-frame industrial gas turbines operating in simple-cycle and/or combined-cycle configurations with steam turbines; scope may also include other plant control systems. The role includes customer training and remote and on-site technical support, including support for installation, integration, commissioning, operations, and troubleshooting.

Requirements

Bachelor’s degree in Engineering from a four-year college or university and at least six years of related experience and/or training, or an equivalent combination of education and experience in relevant control disciplines such as APC, DCS, or PLC applied to power plants.
Practical understanding of power plant processes, including gas turbine and combined-cycle operations, and 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; ability to troubleshoot complex control issues.
Experience with DCS platforms such as DIASYS Netmation, Ovation, DeltaV, 800xA, T3000, or equivalent PLC/DCS platforms, including independent configuration, testing, and troubleshooting of standard system functions.
Ability to perform logic verification and validation using simulation tools or test platforms.
Experience participating in FAT and SAT, including executing test procedures, documenting results, and supporting issue resolution.
Ability to develop and interpret software development workflows, control narratives, SAMA diagrams, Cause & Effect matrices, software validation tests, and interlock logic with limited guidance.
Ability to translate process and operational requirements into robust, reliable control strategies.
Ability to contribute to standardization of logic design practices and templates.
Working knowledge of version control and change management for control logic, including documentation and traceability of changes.
Experience with HMI graphic creation tools and familiarity with ISA-101 High-Performance HMI concepts; ability to develop standard operator displays.
Exposure to alarm management concepts and familiarity with ISA-18.2 principles.
