·      Plan and execute PM and servicing activities to maintenance manuals and client specifications.

·      Supervise and coordinatetechnicians/contractors on-site: manpower planning, task allocation, toolbox briefings, and workmanship checks.

·      Oversee insulating oil activities (where applicable): draining, internal cleaning, foreign object checks, refilling/topping-up, and record oil quality checks.

·      Ensure required testing is performed and recorded (e.g., dielectric strength, insulation resistance, partial discharge checks) and that test instruments are within calibration.

·      Coordinate urgent/emergencyrectification works and mobilise within required timeframes when on-call.

3) Burner / Industrial M&E Service Support

·      Perform PM visits using checklists; document condition, parts used, and improvement recommendations.

Requirements (Must-Have)

·      Diploma/ITE in Electrical Engineering, Mechanical Engineering, Mechatronics, Building Services/M&E, or equivalent technical qualification.

·      Hands-on maintenance/serviceexperience (e.g., MV switchgear/RMUs, substation equipment, industrial M&E systems, controls, pumps, instrumentation).

·      Good understanding of PTW workflows, basic risk control practices, and field safety supervision.

·      Able to read technicaldrawings/manuals, follow checklists, and write clear job reports.

·      Customer-facing communication and professional on-site conduct.

·      Physically fit for field work; willing to travel to customer sites in Singapore; able to support urgentcall-outs when required.

Nice-to-Have

·      Experience with MVswitchgear/RMU servicing and insulating-oil handling (training can be provided depending on site needs).

·      Exposure to burners/boilers, burner controls/ignition components, fuel-train components, pumps, or industrial controls.

·      Valid Class 3 driving licence.

Working Conditions

·      Worksites: client substations, switchrooms, and industrial/commercial facilities (islandwide).

·      Work hours typically aligned to client working hours; overtime/after-hours works may be required for outages and urgent rectification.

·      Occasionalconfined/limited-access switchroom work and strict adherence to site safety controls.
