Core Responsibilities

Primary Functions

Meticulously assemble and install a wide range of mechanical components, including engines, alternators, radiators, fuel tanks, and mounting brackets, following detailed engineering blueprints and work instructions.
Perform intricate electrical assembly tasks, such as routing, terminating, and connecting wiring harnesses to control panels, sensors, and various power system components.
Utilize a variety of hand, power, and pneumatic tools, including torque wrenches, impact guns, drills, and crimpers, ensuring all fasteners and connections are secured to specified values.
Interpret complex engineering drawings, mechanical blueprints, electrical schematics, and manufacturing process documents to guide the assembly process accurately.
Conduct in-process quality checks and visual inspections at various stages of assembly to identify and rectify any defects, misalignments, or non-conformances.
Mount and align engine and generator components onto structural steel bases or within enclosures, verifying proper fit and clearance according to design specifications.
Install and connect fluid systems, including fuel lines, coolant hoses, and lubrication systems, ensuring leak-free connections and proper routing.
Prepare and install sound-attenuated enclosures, including fitting panels, installing insulation, and mounting hardware like doors and access panels.
Operate material handling equipment, such as overhead cranes, jib cranes, and forklifts, to safely move and position large, heavy components like engines and generator ends.
Perform sub-assembly tasks, preparing smaller component groups like battery trays, control boxes, or exhaust systems for integration into the main generator unit.
Collaborate closely with quality control inspectors to ensure all assembly work passes rigorous inspection points and meets company and industry standards.
Document assembly progress and report any issues, part shortages, or discrepancies with blueprints to the team lead or production supervisor in a timely manner.
Follow all established safety protocols, including Lockout/Tagout (LOTO) procedures, proper use of Personal Protective Equipment (PPE), and safe-lifting practices.
Assist in the initial setup and basic functional testing of assembled units to verify the proper operation of installed components before they move to the final test bay.
Maintain a clean, organized, and safe work area, adhering to 5S principles and contributing to a culture of continuous improvement and operational excellence.
Read and apply torque specifications accurately to critical fasteners throughout the engine and generator assembly to ensure structural integrity and operational safety.
Install and configure customer-specific options and accessories, such as block heaters, battery chargers, or custom monitoring devices, based on a production bill of materials.
Troubleshoot and resolve minor assembly issues, such as part interference or fitment problems, by making minor adjustments or collaborating with engineering for a solution.
Manage and account for all parts and hardware assigned to a specific job or work order, minimizing waste and ensuring component traceability.
Participate in team meetings and continuous improvement initiatives aimed at enhancing production efficiency, product quality, and workplace safety.

Secondary Functions

Support ad-hoc rework or repair tasks on units that have failed final testing, working from technical feedback to correct assembly errors.
Contribute to the training and mentoring of new or less-experienced assemblers, sharing knowledge of best practices and procedures.
Collaborate with the inventory team to report part shortages or identify incorrect components received for an assembly job.
Participate in pilot builds for new product introductions, providing valuable feedback to the engineering team on assembly feasibility and process improvements.
