GENERATOR TECHNICIAN — CAT & PERKINS

The Generator Technician will be responsible for the day-to-day operation, preventive maintenance, fault diagnosis, and repair of diesel standby generator sets (CAT and Perkins platforms) ranging from mid-range to large industrial capacities, as part of a layered, multi-source power management system (grid, generators, solar hybrid, and UPS). The role requires a technician who can work independently on routine PM tasks while escalating complex faults appropriately, and who understands the operational discipline required on a live, 24/7, high-footfall facility.

•Carry out scheduled preventive maintenance (weekly, minor/Type 1, major/Type 2, and extensive/Type 3 servicing) on diesel generator sets in line with OEM (CAT/Perkins) intervals and manufacturer guidelines.

•Perform daily/weekly checks: oil and coolant levels, battery voltage, fuel levels, leak inspection, exhaust system inspection, and auto-start/exercise run tests.

•Diagnose and troubleshoot mechanical, electrical, and control system faults on generator sets, including AMF/ATS panels, and carry out first-line repairs.

•Support load bank testing, injector calibration, governor calibration, and coolant system servicing during major and extensive service cycles.

•Monitor fuel management systems and support maintenance of minimum reserve levels for continuous standby readiness.

•Maintain accurate maintenance logs, service records, and defect reports using the facility's CMMS/CAFM platform.

•Respond promptly to generator-related emergency call-outs and support incident response for power failure events, including out-of-hours where required.

•Ensure safe isolation, lock-out/tag-out (LOTO), and safety interlock procedures are strictly followed at all times — no bypassing of safety systems under any circumstance.

•Liaise with the Chief Engineer / Lead Engineering staff on parts requisition, defect escalation, and PPM scheduling.

•Support onboarding of new generator units and condition assessments as required.

•Maintain a clean, safe, and organised generator room/plant area at all times.

Requirements

•OND/HND or Trade Certificate in Mechanical Engineering, Electrical Engineering, or a related technical discipline (relevant hands-on experience will also be considered).

•Minimum 3–6 years' hands-on experience maintaining and repairing diesel standby generators, with direct working knowledge of CAT (Caterpillar) and Perkins engine platforms.

•Practical experience across generator capacity ranges from ~500 kVA up to 1,500 kVA+ (industrial/commercial standby power).

•Working knowledge of AMF/ATS control panels, load bank testing procedures, and basic power management principles.

•Manufacturer-recognised technical training/certification (CAT or Perkins) is an advantage.

•Comfortable working with a CMMS/CAFM system for logging maintenance activity (training provided if not previously used).

•Strong fault-finding and diagnostic skills, with a methodical, safety-first approach to work.

•Willingness to work shifts, be on standby/on-call, and respond to emergency call-outs outside normal hours.

•Good communication skills and the ability to work as part of a wider engineering team on a live operational site.

•Physically fit and able to work in a plant-room/industrial environment (climbing, lifting, confined spaces where applicable).

Benefits

•Competitive salary commensurate with experience.

•Structured PPM environment with clear procedures, tools, and CMMS support.

•Opportunity to work on a large-scale, high-profile facility with a diverse and modern power infrastructure (grid, generator fleet, solar hybrid, UPS).

•Career development within a growing Integrated Facilities Management company.
