Core Responsibilities

Primary Functions

  1. Perform microbiological testing of raw materials, in‑process samples, finished products, utilities and environmental samples (bioburden, endotoxin, sterility, microbial identification) in full compliance with SOPs, GMP and GLP standards.
  2. Execute analytical method qualification, validation and transfer activities under guidance, including development of validation protocols, execution, and documentation.
  3. Review and approve laboratory data, perform peer review of results, evaluate trends and support investigations into out‑of‑specification (OOS) or out‑of‑trend (OOT) events.
  4. Support and perform environmental monitoring programmes in clean rooms, utilities (water, gases, steam) and manufacturing support systems, including viable/non‑viable particulate monitoring and media fill assessments.
  5. Manage and maintain culture collections, growth promotion media, microbial stocks, media sterilisation, expiry checks and equipment used in microbiology testing.
  6. Operate and maintain laboratory instrumentation including autoclaves, biosafety cabinets, incubators, microscopes, plate‑readers, LIMS systems, and ensure calibration, validation and documentation of instrument status.
  7. Document all laboratory procedures, test results and data entries in compliance with good documentation practice (GDP) and ensure sample traceability and chain‑of‑custody.
  8. Investigate deviations, root‑cause analysis, corrective and preventive action (CAPA) initiation, change control management and implement improvements in microbiology test workflows.
  9. Participate in internal and external audits, regulatory inspections, contribute to audit readiness, respond to inspection findings and implement required actions.
  10. Monitor, trend and report laboratory key performance indicators (KPIs) such as turnaround time, contamination rates, sample throughput, instrument uptime, and support continuous improvement initiatives.
  11. Provide training, mentoring and technical support to junior microbiology analysts, technicians or interns, and contribute to competence development and laboratory culture of quality.
  12. Maintain inventory of microbiology‑specific reagents, consumables, culture media, lab supplies; coordinate procurement, stock reorder and manage supplier relationships.
  13. Manage sample receipt, labelling, preparation and initial processing of microbiological samples; ensure timely workflow from sample receipt through testing to final review.
  14. Review and author/update SOPs, WIs, test methods, control documents and ensure that documentation reflects current practices, methods and regulatory expectations.
  15. Collaborate with cross‑functional teams (Manufacturing, Engineering, MSAT, QA) to resolve microbiological issues relating to product safety, contamination control, process improvements and root‑cause investigations.
  16. Ensure laboratory and environmental safety including biosafety, chemical safety, waste disposal, clean‑work practices, adherence to safety policies and support EHS programmes.
  17. Support method development or technical transfer activities for microbiological methods (e.g., bioburden, endotoxin, sterility), including statistical evaluation of method performance and capability.
  18. Ensure compliance with compendial standards (USP, EP, JP), regulatory requirements and international guidelines for microbiology testing and data integrity.
  19. Participate in process improvement initiatives such as lean lab, 5S, continuous improvement programs and standardisation of microbiology workflows.
  20. Support stability testing, cleaning validation studies, process validation activities and product lifecycle support as needed for microbiological testing and sample release.

Secondary Functions

  • Support ad‑hoc data requests and exploratory data‑analysis of microbiological test results to inform investigation or process improvement.
  • Contribute to the organisation’s microbiology strategy and roadmap, including digitalisation of microbiology lab systems, workflow automation and improved data management.
  • Collaborate with product development or engineering teams to translate microbiology operational needs into technical or product specifications and participate in agile planning or continuous improvement initiatives.
