The position offers strong opportunities for professional growth within a rapidly expanding chemical manufacturing environment.

Responsibilities

+ Perform quality control testing on raw materials, in-process samples, and finished products to verify compliance with established specifications.

+ Operate and maintain Gas Chromatography (GC) systems to analyze samples according to approved methods.

+ Operate and maintain High Performance Liquid Chromatography (HPLC) systems to perform detailed analytical testing.

+ Use UV-Visible spectrophotometers to conduct optical absorption and related analyses.

+ Use infrared (IR) and FTIR spectrophotometers to perform qualitative and quantitative analyses of samples.

+ Conduct pH analyses and other routine measurements to support quality control decisions.

+ Perform residue after evaporation testing, fluorescents testing, and other specialized analyses as required.

+ Utilize wet chemistry methods, including titrations and other classical techniques, to analyze samples accurately.

+ Set up daily standards, daily Karl Fischer (KF) calibrations, and special-purpose laboratory equipment to ensure accurate and reliable testing.

+ Plan and prioritize the sequence of testing for incoming samples to meet operational and production needs.

+ Review, interpret, and summarize analytical data to support quality assessments and decision-making.

+ Record analytical results using good documentation practices to ensure traceability and compliance with quality requirements.

+ Communicate effectively with the QC team and cross-functional teams to share results, raise issues, and support problem-solving.

+ Play an active role in the quality management team by contributing to continuous improvement of laboratory methods and processes.

+ Support raw material testing, in-process analysis, and finished goods testing within a chemical manufacturing environment.

+ Assist with quality assurance activities and formulations support as experience grows.

+ Follow all laboratory procedures, test methods, and safety protocols consistently.

+ Perform other related duties as assigned to support laboratory and quality operations.
