• Proficiency in database interaction, specifically SQL querying and stored procedures.
• Familiarity with the Visual Studio development environment.
• Experience supporting systems running on or interfacing with Cway.

• A tertiary qualification in Electrical Engineering, Automation, Mechatronics, or an equivalent technical field is highly desirable.
• A proactive commitment to safety and proven experience working within stringent industrial safety standards is essential.
• Superior problem-solving capabilities and the capacity to operate effectively and autonomously under pressure.
• Exceptional communication skills, required for effective liaison with all levels of site personnel.
