• Working knowledge of electrical, mechanical, and networking fundamentals.
• Experience supporting control systems, instrumentation, field devices, and industrial communication networks.
• Ability to read and interpret electrical schematics, wiring diagrams, control drawings, and technical documentation.
• Experience troubleshooting sensors, relays, controllers, communication networks, and monitoring systems.
• Proficiency using diagnostic and testing equipment, including multimeters and network troubleshooting tools.
• Strong analytical and problem-solving skills with a structured troubleshooting approach.
• Experience following commissioning processes, operational procedures, and change management requirements.

• Experience working in environments where reliability, safety, and operational continuity are critical.
• Understanding of operational risk and the importance of procedural compliance in live facilities.
• Ability to maintain accurate documentation and execute work with a high degree of attention to detail.
