Core Responsibilities

Primary Functions

Conduct a comprehensive range of physical, chemical, and microbiological tests on raw materials, work-in-progress, and finished products according to Standard Operating Procedures (SOPs).
Accurately document all test results, observations, and procedural deviations in laboratory notebooks and the Laboratory Information Management System (LIMS) in real-time.
Operate, calibrate, and perform routine maintenance on sophisticated laboratory instrumentation such as spectrophotometers, chromatographs (HPLC/GC), viscometers, titrators, and moisture analyzers.
Immediately identify, quarantine, and report any out-of-specification (OOS) or non-conforming materials and products to the Quality Supervisor for further investigation.
Prepare and standardize chemical reagents, solutions, and microbiological media required for daily analytical testing, ensuring proper labeling and storage.
Perform environmental monitoring within the manufacturing facility, including ATP swabbing, water sampling, and air quality testing, to ensure a sanitary production environment.
Maintain the laboratory in a clean, organized, and safe manner, adhering to 5S principles, GLP (Good Laboratory Practices), and all company safety protocols.
Place holds on finished products that do not meet quality standards and assist in the disposition process, including rework or rejection protocols.
Review production batch records for completeness and accuracy, verifying that all in-process quality checks were performed and documented correctly.
Collect and properly log incoming samples from production, receiving, and R&D, ensuring a clear chain of custody is maintained at all times.
Perform sensory evaluations (e.g., taste, color, odor, appearance) on products as required by specific industry standards, such as in food and beverage manufacturing.
Execute stability testing protocols by pulling samples at specified intervals and performing required tests to assess product shelf life and integrity over time.
Verify the proper setup and cleanliness of production lines before startup, performing sanitation checks and line clearance approvals.

Secondary Functions

Assist in the investigation of customer complaints by retrieving retain samples and performing targeted analytical testing to help determine the root cause.
Participate actively in root cause analysis (RCA) teams for internal non-conformances, providing data-driven insights and suggestions for corrective and preventive actions (CAPAs).
Support the validation of new test methods and the qualification of new laboratory equipment under the guidance of senior quality personnel or engineers.
Contribute to the continuous improvement of laboratory processes by suggesting updates to SOPs, test methods, and workflows to enhance efficiency and accuracy.
Manage the inventory of laboratory consumables, chemicals, and supplies, initiating purchase requisitions to prevent stock-outs of critical items.
Provide training and guidance to new technicians or production operators on specific quality control checks, testing procedures, and proper sampling techniques.
Compile and analyze quality data to generate trend reports, charts, and summaries for daily, weekly, and monthly quality review meetings.
Participate in internal and third-party audits (e.g., FDA, ISO, SQF) by providing documentation, explaining lab procedures, and ensuring the lab is audit-ready.
