Core Responsibilities

Primary Functions

Execute the manual assembly of intricate mechanical, electro-mechanical, or electronic components and sub-assemblies by following detailed work instructions, assembly drawings, and process specifications.
Operate a variety of hand tools, power tools, and specialized production equipment such as torque wrenches, crimpers, soldering irons, and presses to fasten, connect, and modify parts.
Meticulously read and interpret complex blueprints, technical drawings, schematics, and wiring diagrams to ensure accurate component placement and assembly sequence.
Perform in-process quality checks and visual inspections on parts, sub-assemblies, and finished products to identify defects, non-conformities, or cosmetic flaws, ensuring adherence to quality standards.
Use precision measuring instruments, including calipers, micrometers, and gauges, to verify that parts and assemblies meet strict dimensional tolerances and specifications.
Prepare components for assembly by cleaning, deburring, and positioning them, as well as applying adhesives, lubricants, or other materials as required by the assembly process.
Responsible for routing, wiring, and terminating connections for electronic assemblies, which may include soldering and crimping techniques to create secure and functional electrical pathways.
Set up and configure workstations and equipment according to job requirements, ensuring all tools and materials are readily available to maintain workflow efficiency.
Document production and quality control data accurately by completing work orders, logs, and traceability records, either manually or using a computer-based system (MES).
Adhere strictly to all company safety policies and procedures, including the use of personal protective equipment (PPE) and maintaining a clean, organized, and safe work area (5S principles).
Collaborate with team members, supervisors, and engineering staff to troubleshoot assembly issues, resolve production bottlenecks, and contribute to process improvement initiatives.
Rotate through different tasks and stations on the assembly line as required to support production needs and develop a broader skill set.
Manage and maintain an inventory of parts and supplies at the workstation, notifying supervisors or material handlers when stock is low to prevent production delays.
Perform basic testing and functional checks on completed assemblies to ensure they operate correctly before being passed to the next stage of production or final inspection.
Carefully package finished products according to specifications to protect them from damage during handling and transport.
Disassemble, modify, rework, and repair defective products or components that do not meet quality standards, following specific rework instructions.
Participate in continuous improvement (Kaizen) events and provide constructive feedback to enhance production efficiency, product quality, and workplace safety.
Train and mentor new or less experienced assemblers on standard operating procedures, quality standards, and safe work habits.
Handle and process sensitive electronic components in an Electrostatic Discharge (ESD) safe environment, following all ESD protocols to prevent damage.
Monitor the performance of assembly equipment and perform routine preventative maintenance to ensure it remains in good working order, reporting any malfunctions for repair.

Secondary Functions

Assist in regular inventory counts and material stocking to ensure accuracy and availability of components for the production line.
Contribute to team meetings by providing updates on progress, raising concerns, and suggesting potential solutions to assembly-related challenges.
Support engineering and quality departments by assisting with pilot builds and providing feedback on new product assembly processes.
Maintain cleanliness and organization of the overall production floor, not just the immediate workstation, contributing to a lean and efficient environment.
