• You’ll be an excellent communicator with a customer-focused approach.
• You’ll be confident with computers and willing to learn new systems.
• You’ll be keen to learn and develop, with full training provided.
• Previous experience in plant operations is desirable but not essential. Soft skills, reliability, and a proactive attitude are most important.
