Scope of Work

The Field Service Engineer - Control Engineer will provide on-site technical expertise for installation, commissioning, maintenance, troubleshooting, and retrofits of rotating equipment control systems. The primary focus of this role involves deploying, calibrating, and upgrading General Electric (GE) Mark series turbine control systems (specifically Mark V, Mark VI, and Mark VIe / Mark VIeS) applied to heavy-duty gas turbines, steam turbines, and associated generator/compressor packages.

Duties & Responsibilities

• Execute complete site activities including pre-commissioning, cold loop checks, hot loop checks, signal point-to-point verification, turbine first-fire sequences, synchronization, and full-load testing;
• Modify, upload/download, debug, and verify application software using Toolbox and ToolboxST across Mark VI and Mark VIe controller platforms;
• Configure, calibrate, and troubleshoot field instrumentation, servo valves, LVDTs (Linear Variable Differential Transformers), RTDs, thermocouples, 4-20 mA transducers, and electro-hydraulic actuators;
• Configure and support Human-Machine Interfaces (Cimplicity, iFix), auxiliary network switches, UDH/PDH Ethernet networks, Modbus (RTU/TCP), and Profibus/Foundation Fieldbus communication links;
• Diagnose software alarms, controller hardware faults, network latency issues, trip events, and turbine run-up logic discrepancies under tight outage deadlines;
• Support legacy control migration projects (e.g., Mark IV / Mark V to Mark VIe conversions), including cabinet terminations, I/O verification, and legacy sequencing translations;
• Generate daily progress reports, trip investigations, punch lists, redline electrical drawings, and technical field service reports (FSR). Adhere strictly to site-specific Lockout/Tagout (LOTO) protocols, Permit to Work (PTW) requirements, and OSHA/industry safety standards.

Required Competences

• Hands-on operational and engineering knowledge of GE Mark V, Mark VI, and Mark VIe hardware (including controller racks, power distribution modules, terminal boards, and I/O packs).
• Practical experience using GE Control System Toolbox and ToolboxST for logic configuration, trend creation, sequence editing, and alarm diagnostics;
• Strong grasp of gas and steam turbine operating philosophies (speed/load control, fuel stroke reference [FSR], start-up sequences, acceleration control, temperature control/exhaust spreads, and turbine protection/trip logic);
• Knowledge of Ethernet topologies, TCP/IP, Modbus, Profibus, and proprietary GE UDH (Unit Data Highway) and PDH (Plant Data Highway) architectures;
• Advanced ability to read and redline Piping and Instrumentation Diagrams (P&IDs), Instrument Loop Diagrams (ILDs), single-line diagrams, and wiring schematics.

Qualifications

• Bachelor's Degree in Mechanical Engineering, Industrial Engineering, or a related technical discipline. (Significant, direct field experience may be substituted for formal education);
• Minimum of 5 years of experience as a Field Service Engineer, Technical Advisor, or Millwright working specifically with heavy rotating equipment.

Location

• Saudi Arabia
