- Perform mechanical diagnostics, component replacements, and precision alignment.
- Carry out condition monitoring (vibration analysis, oil sampling, thermography).
- Maintain HVAC/cooling systems for control rooms and generator enclosures.
- Work safely within permit-to-work systems, including hot work, confined space and pressure systems.
- Support audits, documentation, and environmental/emissions reporting.
- Collaborate with electrical and operations teams during plant start-ups, shutdowns and testing.
Skills & Experience Required
- Experience in power generation, utilities, CHP, energy conversion, or heavy industrial maintenance.
- Expertise with fuel-oil systems, industrial gas installations, gas & steam turbines, diesel generators and boilers.
- Ability to make informed decisions on plant outages, backups and safe recovery of systems.
- Understanding of emergency actions during service outages.
- Qualification: National Craft Certificate or Level 6+ in Mechanical Fitting, Industrial/Plant Maintenance, Marine Engineering, or equivalent.
- 2–4 years’ experience with rotating machinery, power gen equipment or critical mechanical / electrical systems.
- Strong knowledge of lubrication systems, gas engines and thermal management.
- Ability to read mechanical / electrical drawings, P&IDs and schematics.
- Skilled in fault-finding, alignment, and condition-based maintenance.
- Excellent safety awareness and teamwork.
Equipment & Systems Exposure
Gas engines/turbines, fuel & oil pumps, mechanical seals, HVAC plant, chillers, water/glycol systems, vibration probes, IR thermography and more.
Additional Information
