Core Responsibilities

Primary Functions

  • Perform routine and non-routine microbiological testing, including bioburden (microbial enumeration), bacterial endotoxin (LAL), and sterility testing on raw materials, in-process materials, and finished biopharmaceutical products.
  • Conduct comprehensive environmental monitoring of ISO classified cleanrooms, including viable air sampling, surface sampling (contact plates/swabs), and personnel monitoring.
  • Execute Utilities monitoring, including sampling and testing of Water-for-Injection (WFI), purified water, and clean steam systems.
  • Aseptically perform sample collection, preparation, and analysis in accordance with established Standard Operating Procedures (SOPs) and pharmacopeial methods (USP, EP, JP).
  • Accurately read, document, and interpret microbiological test results, identifying and reporting any excursions or out-of-trend (OOT) data.
  • Initiate and conduct laboratory investigations for Out of Specification (OOS) results, deviations, and environmental monitoring excursions, utilizing root cause analysis tools.
  • Author and participate in the implementation of Corrective and Preventive Actions (CAPAs) to address and prevent recurrence of microbiological issues.
  • Maintain and manage the inventory of microbial cultures, media, and reagents, ensuring proper qualification, growth promotion, and traceability.
  • Perform microbial identification of isolates from environmental, utility, and product samples using techniques such as Gram staining, and automated systems (e.g., VITEK, MALDI-TOF).
  • Author, review, and revise technical documents, including SOPs, test methods, validation protocols, and summary reports.

  • Maintain meticulous and contemporaneous records of all testing activities using laboratory notebooks and electronic systems like Laboratory Information Management Systems (LIMS).
  • Calibrate, qualify, and maintain laboratory instrumentation and equipment, such as autoclaves, incubators, biosafety cabinets, and particle counters.
  • Participate in the validation, transfer, and verification of new microbiological test methods.
  • Support internal and external regulatory audits (e.g., FDA, EMA) by providing data, documentation, and subject matter expertise.
  • Trend microbiological data from environmental monitoring and utility systems to monitor the state of control and identify potential risks.
  • Provide microbiological support and expertise to cross-functional teams including Manufacturing, Engineering, and Quality Assurance.
  • Adhere strictly to all safety guidelines and procedures when handling hazardous materials and microbial cultures.
  • Perform growth promotion testing of microbiological media to ensure its suitability for use.
  • Train junior analysts on laboratory procedures, aseptic technique, and cGMP documentation practices.

Secondary Functions

  • Support laboratory and regulatory audits by preparing documentation and responding to inquiries as a subject matter expert.
  • Contribute to continuous improvement initiatives within the QC laboratory to enhance efficiency, compliance, and safety.
  • Assist in managing laboratory inventory, ordering supplies, and ensuring the lab is well-stocked for routine operations.
  • Participate in cross-functional team meetings to provide microbiological insights for projects, process changes, and investigations.
