• Respond to service requests within agreed timeframes and aim to resolve issues effectively on the first visit.
• Complete service and commissioning records, including findings, work undertaken, parts used, recommendations and customer acknowledgement.
• Record site activity in the company’s service-management and digital field-service systems, and provide customers with practical technical advice.
• Flag potential maintenance, repair, replacement or upgrade work, and coordinate assistants, subcontractors or other site personnel when needed.
• Look after assigned tools, test equipment, stock and vehicles, and follow applicable safety, environmental, warranty and technical procedures.

• Diploma or higher diploma in Water, Mechanical or Electrical Engineering, or an equivalent technical qualification from a recognised institution.
• At least three years of relevant experience installing, commissioning, maintaining and troubleshooting water-treatment plants.
• Practical fault-finding skills covering pumps, dosing equipment, filters, valves, control panels, instrumentation and associated systems.
• Working knowledge of mechanical, electrical, hydraulic and control systems.
• Valid driving licence and willingness to travel extensively for field assignments.
