Core Responsibilities

Primary Functions

Independently perform a wide range of complex analytical tests on raw materials, in-process samples, and finished products to ensure they meet stringent quality and safety standards.
Operate, maintain, and calibrate sophisticated analytical instrumentation such as HPLC, GC, GC-MS, FTIR, UV-Vis, and titration equipment, ensuring optimal performance.
Develop, validate, and transfer new analytical test methods in accordance with industry guidelines (e.g., ICH, USP, FDA) to support new product development and lifecycle management.
Troubleshoot and resolve complex issues with laboratory instruments, test methods, and unexpected results, applying a systematic and scientific approach.
Meticulously document all experimental work, observations, and results in laboratory notebooks and electronic systems (LIMS) with a high degree of accuracy and in compliance with cGMP/GLP.
Author, review, and revise technical documents, including standard operating procedures (SOPs), test methods, validation protocols, and technical reports.
Conduct and lead investigations into out-of-specification (OOS), out-of-trend (OOT), and other aberrant laboratory results, identifying root causes and implementing corrective actions.
Prepare chemical solutions, standards, and reagents needed for analysis, ensuring proper handling, labeling, and storage.
Analyze and interpret complex analytical data, using statistical methods where appropriate, and prepare comprehensive reports summarizing findings for both technical and non-technical audiences.
Ensure all laboratory activities are conducted in strict compliance with established safety protocols, environmental regulations, and current Good Manufacturing Practices (cGMP).
Manage the laboratory's chemical and consumable inventory, including ordering supplies, tracking usage, and ensuring proper disposal of chemical waste.
Perform peer review of analytical data generated by other chemists to ensure accuracy, completeness, and compliance with established procedures.
Conduct stability studies on products by testing samples at various time points and environmental conditions to determine shelf-life and degradation profiles.
Support process improvement and validation activities by providing analytical testing and expertise for manufacturing and cleaning validation protocols.
Interface with other departments such as Quality Assurance, Manufacturing, and R&D to provide analytical support and collaborate on cross-functional projects.
Stay current with advances in analytical chemistry, instrumentation, and relevant regulatory guidelines through continuous learning and professional development.
Analyze competitor products or perform deformulation studies to support research and development initiatives.
Prepare and analyze samples for physical property testing, such as viscosity, pH, particle size, and density, as required by product specifications.
Participate actively in internal, client, and regulatory audits (e.g., FDA, ISO), serving as a subject matter expert for laboratory operations.
Execute and document method equivalency studies to justify the use of updated or alternative analytical procedures.

Secondary Functions

Participate in laboratory safety committees and promote a culture of safety and compliance among peers.
Assist in the training and mentorship of junior chemists and laboratory technicians on new techniques and procedures.
Contribute to continuous improvement projects aimed at increasing laboratory efficiency, reducing turnaround times, and minimizing waste.
Support internal and external audits by providing documentation, explaining laboratory procedures, and answering technical questions from auditors.
