The Quality Control Laboratory Technician performs chemical, physical, and instrumental testing to ensure the quality of raw materials, in-process samples, finished products, and customer samples. This role follows established analytical procedures, validates and troubleshoots test methods, and maintains accurate laboratory documentation. The technician works closely with Quality, Production, and R&D teams, handles hazardous materials safely, and supports process control through precise data collection and analysis.

Responsibilities

+ Perform chemical, physical, and instrumental testing on raw materials, in-process samples, finished products, and customer product samples using techniques such as volumetric and gravimetric analyses, pH measurement, FTIR, specific gravity (SPG), refractive index (RI), and other instrumental methods.

+ Conduct functional testing, including IACS and thermal conductivity measurements, as needed to support product evaluation and quality assurance.

+ Follow written analytical procedures and standard operating procedures (SOPs) to ensure consistent and accurate testing.

+ Validate established analytical methods and troubleshoot testing procedures to maintain and improve product quality.

+ Collect, enter, review, and validate test data in WinLIMS or similar data management systems, ensuring accuracy and completeness.

+ Perform calculations based on test results and submit data for review and approval by the appropriate supervisor or manager.

+ Communicate sample status, test progress, and final results clearly and promptly to Quality, Production, and R&D teams.

+ Maintain accurate and up-to-date laboratory documentation, including SOPs, test methods, protocols, deviations, batch records, and Certificates of Analysis (COAs).

+ Handle hazardous materials safely by following proper storage, labeling, handling, and disposal procedures in accordance with site safety and chemical hygiene protocols.

+ Adhere to all site safety guidelines, chemical hygiene plans, and laboratory best practices to maintain a safe working environment.

+ Troubleshoot basic process and testing issues, identify potential root causes, and escalate complex problems appropriately.

+ Support process control by focusing on accurate documentation, consistent testing practices, and adherence to quality standards.

+ Collaborate effectively with team members, share information, and contribute to a cooperative and efficient laboratory environment.

Essential Skills

+ Bachelor of Science degree in Chemical Engineering, Chemistry, Materials Science, or a related field.

+ Experience in quality control and analytical testing in a laboratory environment, including exposure to materials testing, metals, or related disciplines.

+ Hands-on laboratory experience, which may include academic laboratory work or industry-based lab roles.

+ Proficiency in performing chemical and physical tests such as volumetric and gravimetric analyses, pH measurement, FTIR, specific gravity (SPG), refractive index (RI), and related instrumental techniques.

+ Ability to conduct functional testing, including IACS and thermal conductivity measurements, or willingness to learn these techniques.

+ Basic computer skills, including the use of Microsoft Excel, Word, and PowerPoint, and the ability to log and manage process data.

+ Ability to collect, enter, review, and validate data in laboratory information management systems such as WinLIMS or similar platforms.

+ Strong attention to detail with a focus on process control, accurate documentation, and maintaining high quality standards.

+ Ability to work effectively in a team environment, follow written and verbal instructions, and communicate clearly with colleagues and cross-functional teams.

+ Good time management skills, including the ability to prioritize tasks, manage multiple assignments, and meet deadlines.

+ Capability to handle hazardous materials safely and follow established safety and chemical hygiene protocols.

Additional

Skills & Qualifications

+ Knowledge in materials testing or experience working with metals is highly beneficial.
