Core Responsibilities

Primary Functions

Skillfully set up and prepare various types of light machinery for production runs, including calibration, cleaning, and installing necessary components or tooling.
Operate production equipment according to precise Standard Operating Procedures (SOPs), work orders, and manufacturing specifications to ensure consistency and quality.
Continuously monitor machine operations to detect any deviations, malfunctions, or abnormalities, making swift adjustments to maintain optimal performance.
Perform in-process quality control checks on parts and products using precision measuring tools like calipers, micrometers, and gauges to ensure they meet stringent tolerance and quality requirements.
Accurately read and interpret technical documents, including blueprints, engineering drawings, and schematics, to understand part specifications and production requirements.
Adjust machine settings such as speed, feed, and temperature as needed during a production cycle to maintain quality standards and production efficiency.
Safely and efficiently load raw materials into machine hoppers or feeders and carefully unload finished parts, ensuring proper handling to prevent damage.
Execute routine preventative maintenance on machinery, such as lubrication, cleaning of parts, and minor repairs, to minimize downtime and prolong equipment life.
Identify, diagnose, and troubleshoot minor operational problems or machine faults, escalating more complex issues to maintenance technicians or supervisors in a timely manner.
Maintain detailed and accurate records of production output, machine performance, quality checks, and instances of downtime or scrap material.
Strictly adhere to all company and industry safety regulations, including the consistent use of Personal Protective Equipment (PPE) and following Lockout/Tagout (LOTO) procedures during maintenance.
Uphold a high standard of housekeeping by maintaining a clean, organized, and safe work environment around the machinery and within the production cell.
Verify dimensions and alignment of finished parts to ensure they conform to specifications, making adjustments or stopping production if non-conformance is found.
Collaborate effectively with fellow operators, quality inspectors, and shift supervisors to coordinate workflow and ensure production targets are achieved as a team.
Promptly report any significant equipment malfunctions, potential safety hazards, or major quality deviations to the appropriate personnel for resolution.
Manage and monitor the consumption of raw materials and supplies, notifying supervisors when inventory levels are running low to prevent production interruptions.
Perform final assembly, packaging, or labeling of products as required, ensuring they are prepared for shipping or the next stage of production.
Assist in the on-the-job training and mentoring of new or less-experienced operators, sharing knowledge of machine operation and safety practices.
Actively participate in continuous improvement initiatives, such as Kaizen events or 5S programs, by providing feedback and suggestions to enhance processes.
Ensure that personal and team production rates meet or exceed established daily and weekly targets without compromising safety or quality standards.

Secondary Functions

Assist with periodic inventory counts of raw materials, work-in-progress, and finished goods within the production area.
Contribute valuable insights and feedback during team meetings aimed at enhancing process efficiency, safety, and product quality.
Provide operational support to adjacent production lines or departments during periods of peak demand or staff shortages.
Participate in root cause analysis discussions and problem-solving teams to address recurring production or quality challenges.
