Our client, a leading organisation within the power generation industry, is seeking six experienced Mechanical Technicians to support a major industrial diesel generator project.

The successful candidates will be responsible for the mechanical assembly, installation and preparation of large-scale diesel generator systems.

This opportunity is suited to technically skilled individuals with proven hands-on experience working on diesel generators, particularly those familiar with large industrial power generation equipment.

Three technicians will be responsible for initial generator assembly within a workshop or designated yard, while three will focus on final assembly and installation at the project site.

Key Responsibilities

• Perform mechanical assembly of large industrial diesel generators within a workshop or designated assembly yard.

• Assemble and fit diesel engines, alternators, mounting systems and associated mechanical components.

• Assist with engine and alternator alignment, coupling and mechanical connections.

• Install associated cooling systems, fuel systems, exhaust assemblies and pipework.

• Read and interpret technical drawings, assembly instructions and mechanical specifications.

• Utilise hand tools, power tools and precision measuring instruments.

• Support the movement, positioning and assembly of heavy generator components alongside qualified lifting and rigging teams.

• Inspect assembled equipment to ensure compliance with technical specifications and quality standards.

• Identify and rectify mechanical defects or assembly-related issues.

• Ensure assembled components are prepared for transportation to the installation site.

• Maintain compliance with occupational health, safety and quality standards.

Key Responsibilities

• Perform mechanical installation and final assembly of large industrial diesel generator systems at project sites.

• Receive, inspect and prepare generator components delivered from the assembly yard.

• Assist with positioning, alignment and installation of heavy mechanical components.

• Carry out final mechanical fitting, assembly and connection of engines, alternators and supporting equipment.

• Install associated fuel supply, cooling, exhaust and mechanical piping systems.

• Coordinate with qualified rigging teams during equipment positioning and installation.

• Interpret engineering drawings, installation layouts and manufacturer specifications.

• Conduct mechanical inspections and identify installation defects.

• Troubleshoot and rectify mechanical installation issues.

• Support pre-commissioning inspections and testing activities.

• Collaborate with engineering, construction and commissioning teams.

• Ensure compliance with site safety procedures and project quality requirements.

Essential - Non-Negotiable

• Proven hands-on experience working specifically with diesel generators or diesel generator sets.

• Experience within industrial power generation, generator manufacturing, generator maintenance or generator installation.

• Strong knowledge of diesel generator mechanical systems and components.

• Demonstrated mechanical fitting, assembly, servicing, repair or installation capabilities involving diesel generators.

• Ability to interpret mechanical drawings and technical documentation.

• Proficiency in mechanical tools, equipment and troubleshooting techniques.

• Strong understanding of workplace safety requirements.

• Ability to work effectively within a technical project team.

• Relevant trade qualification in Mechanical Fitting, Diesel Mechanics or a related mechanical engineering discipline.

• Previous experience working on large industrial diesel generator systems.

• Experience with established industrial diesel generator manufacturers.

• Exposure to generator assembly, heavy mechanical installations or industrial power generation projects.

• Experience supporting data centre, industrial facility or major backup power infrastructure projects.

• Previous project-based, contract or freelance experience.

• Familiarity with heavy equipment positioning, alignment and mechanical installation procedures.

We are looking for practical, technically competent Mechanical Technicians who have gained substantial hands-on experience working with industrial diesel generator systems.

Successful candidates should demonstrate strong mechanical aptitude, attention to detail and the ability to operate safely within workshop and construction-site environments.

Individuals who are currently self-employed, contracting, freelancing or available for project-based assignments are particularly encouraged to apply.

Direct diesel generator experience is mandatory.

Candidates whose experience is limited exclusively to automotive, commercial vehicle, truck, bus or earthmoving diesel engines, without demonstrable diesel generator exposure, will not be considered.
