Core Responsibilities

Primary Functions

Conduct comprehensive analytical testing on raw materials, in-process samples, and finished products using a variety of advanced instrumentation and wet chemistry techniques.
Meticulously review, interpret, and verify analytical data and test results generated by peers to ensure accuracy, completeness, and compliance with established specifications.
Initiate and lead thorough laboratory investigations into Out-of-Specification (OOS) and Out-of-Trend (OOT) results, employing root cause analysis to identify issues and recommend robust corrective and preventive actions (CAPAs).
Execute routine calibration, performance verification, and maintenance of sophisticated laboratory equipment to guarantee operational integrity and data accuracy.
Develop, revise, and meticulously maintain Standard Operating Procedures (SOPs), test methods, and other critical GMP/GLP documentation to reflect current best practices and regulatory standards.
Perform environmental monitoring, including water sampling and testing, air viable/non-viable particulate testing, and surface sampling within controlled manufacturing environments.
Manage laboratory inventory, including the ordering, receipt, and proper storage of chemical reagents, standards, and critical supplies to ensure uninterrupted testing operations.
Author and execute protocols for method validation, verification, and transfer activities in accordance with ICH, USP, and other regulatory guidelines.
Uphold and enforce strict compliance with current Good Manufacturing Practices (cGMP), Good Laboratory Practices (GLP), and all relevant safety and environmental regulations.
Prepare detailed certificates of analysis (CofA), technical reports, and investigation summaries for internal review and regulatory submission.
Participate actively in internal and external audits (e.g., FDA, client audits) by providing documentation, answering technical questions, and demonstrating laboratory procedures.
Conduct stability testing for products according to predefined protocols, managing sample pull schedules, executing tests, and analyzing data to establish product shelf-life.
Provide real-time analytical support to manufacturing and production teams to troubleshoot issues, resolve quality discrepancies, and facilitate smooth operations.
Compile and analyze quality data to identify trends, measure performance against key metrics, and prepare reports for management review.
Train junior analysts and technicians on laboratory procedures, equipment operation, and safety protocols to foster a knowledgeable and capable team.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to assist in non-routine investigations or process improvement projects.
Contribute to the organization's data integrity initiatives, ensuring all electronic and paper-based records are secure and compliant.
Collaborate with cross-functional teams, including R&D, Manufacturing, and Supply Chain, to ensure a seamless and quality-focused product lifecycle.
Participate in sprint planning and agile ceremonies if working within a modern, data-driven quality organization.
Assist in the evaluation and implementation of new laboratory technologies and software (e.g., LIMS, ELN) to enhance efficiency and compliance.
Support material qualification and supplier evaluation programs by performing testing on new sources of raw materials.
Maintain a clean, organized, and safe laboratory environment, adhering to all 5S and EHS principles.
