Utilize a wide range of hand tools, power tools, and precision measurement instruments like calipers, micrometers, and dial indicators to build and meticulously verify assembly accuracy.
Manage the assembly workflow for large-scale machinery, including planning the sequence of operations and coordinating with other departments to ensure an efficient and logical build process.
Route, wire, and terminate a variety of electrical connections, including multi-conductor cables, complex harnesses, and sensitive connectors, following detailed electrical schematics and wiring diagrams.
Install and plumb complete pneumatic and hydraulic systems, including the careful routing and connection of hoses, tubing, fittings, and valves, ensuring leak-free and secure operation.
Mount and integrate a variety of critical components such as motors, pumps, sensors, gearboxes, and control panels onto the main machine frame, ensuring proper alignment and securement.
Conduct comprehensive in-process quality checks and functional tests on sub-assemblies and final products to ensure they meet all operational requirements and stringent quality standards.
Diagnose, troubleshoot, and methodically resolve mechanical, electrical, and pneumatic/hydraulic issues that arise during the assembly, integration, and testing phases of production.
Collaborate directly with engineering and quality assurance teams to identify and document root causes of assembly problems, actively participating in the development of effective corrective actions.
Perform system-level testing and machine start-up procedures, verifying a full range of machine functions and performance metrics to validate operational readiness before shipment.
Make necessary adjustments, calibrations, and modifications to assemblies to correct malfunctions or deviations from specifications, documenting all changes for engineering review.
Maintain meticulous and accurate records of the entire assembly process, including the completion of work orders, inspection reports, and any deviations from standard procedures.
Provide direct, actionable feedback to the engineering department by redlining drawings and suggesting improvements to designs for manufacturability (DFM) and assembly efficiency.
Participate actively in continuous improvement initiatives and Kaizen events, offering valuable suggestions to enhance assembly processes, improve workplace safety, and reduce waste.
Document all non-conformances and collaborate with the Quality department to ensure proper disposition, rework, and re-inspection procedures are followed to the letter.
Adhere strictly to all company safety policies, procedures, and Lockout/Tagout (LOTO) protocols to maintain a safe, clean, and highly organized work environment at all times.
Manage the inventory of parts and components for assigned builds, coordinating with the materials team to prevent shortages and ensure a smooth, uninterrupted workflow.
Prepare finished machinery for shipment, a process which may include partial disassembly, crating, securing, and completing final shipping documentation to ensure safe transit.
Assist in the training and mentoring of junior assemblers, sharing expert knowledge of best practices, specialized assembly techniques, and critical safety standards.

Secondary Functions

Support ad-hoc requests from engineering for prototype builds or special test setups.
Contribute to the organization's goals for on-time delivery and production efficiency.
Collaborate with the Quality Control team to refine inspection criteria and testing procedures.
Participate in team meetings and daily huddles to discuss production schedules, challenges, and safety topics.
