Core Responsibilities

Primary Functions

  1. Collect, label and process microbiological samples (food, water, environmental surfaces, raw materials, finished products) in accordance with standard operating procedures (SOPs).
  2. Prepare and sterilize culture media, reagents, diluents and growth substrates; monitor and document media performance and expiration.
  3. Inoculate, incubate and monitor cultures for bacterial, fungal or viral growth; perform colony counts, biochemical tests, gram staining, and antimicrobial susceptibility tests.
  4. Conduct environmental monitoring including air‑sampling, surface swabbing, water/utility sampling (viable and non‑viable particulate counts), and submit results for review.
  5. Operate, calibrate and maintain laboratory equipment including autoclaves, incubators, biosafety cabinets, microscopes, pipettes and plate‐readers; perform routine checks and document results.
  6. Record and interpret data from microbiological assays, assess whether results meet acceptance criteria, and flag non‑conforming or out‑of‑specification (OOS) results for further investigation.
  7. Support method validation, verification or transfer activities for microbiological tests, assist senior staff with assay optimization and data trending.
  8. Maintain culture collections, microbial stocks, cryopreserved samples, and track inventory of organisms, reagents, consumables and lab supplies; reorder as necessary.
  9. Document all laboratory activities, maintain chain‑of‑custody records, electronic lab notebook entries (ELN/LIMS), ensure data integrity and compliance with GLP/GMP standards.
  10. Perform cleaning, sterilisation and housekeeping of laboratory workspaces, ensure biosafety, biohazard waste disposal and compliance with safety protocols.
  11. Assist with root‑cause investigations, corrective and preventive actions (CAPA), deviation documentation and reporting of results or equipment failures.
  12. Participate in internal and external audits, support quality assurance programmes, ensure laboratory meets regulatory requirements and maintain audit‑ready documentation.
  13. Monitor key performance indicators (KPIs) such as contamination rates, sample turnaround time, culture viability, and propose improvements to enhance throughput and quality.
  14. Collaborate with cross‑functional teams (Quality, Manufacturing, Research & Development, Engineering) to ensure microbiological risk assessment and control strategies are incorporated into product or process design.
  15. Provide training or guidance to junior technicians, interns or new team members on laboratory techniques, aseptic practices, equipment operation and safety procedures.
  16. Assist with sampling protocols for utilities, manufacturing equipment or clean rooms (including water systems and gas systems) to support environmental surveillance programmes.
  17. Ensure that all work is performed according to company policies, standard documentation practices (GDP), SOPs, and that proper record‑keeping is maintained for traceability.
  18. Support continuous improvement initiatives: identify workflow bottlenecks, propose new methods, assist in implementing automation or process enhancements in microbiology workflows.
  19. Stay current with technical literature, new microbiology methods, instrumentation advances and regulatory changes; support the adoption of best practices in the laboratory.
  20. Participate in cross‑lab or cross‑site coordination to ensure standardisation of microbiological methods, data comparability and consistency of results across multiple locations or projects.

Secondary Functions

  • Support ad‑hoc data requests and exploratory data‑analysis of microbiological datasets to inform decision‑making or process improvements.
  • Contribute to the organisation’s microbiology laboratory strategy and roadmap, including equipment upgrades, method consolidation and digitalisation initiatives.
  • Collaborate with engineering or data teams to translate microbiology operational requirements into technical or software specifications; participate in agile‑style planning, sprint reviews or system roll‑outs when applicable.

Required Skills & Competencies

Hard Skills (Technical)

  • Knowledge and hands‑on experience with microbiological culturing, isolation, identification, colony counting, agar plating, streaking, biochemical and antimicrobial testing.
  • Proficiency in preparing microbiological media, reagents, diluents and maintaining culture collections with accurate tracking and inventory management.
  • Ability to use laboratory equipment including autoclaves, biosafety cabinets, incubators, microscopes, pipettes and plate‑readers; perform calibration and routine maintenance.
  • Working knowledge of environmental monitoring tools (air sampling, surface swabs, utility water sampling), viable/non‑viable particulate monitoring and reporting.
  • Experience entering, managing and interpreting data via laboratory information management systems (LIMS)/electronic lab notebooks (ELN) and proficiency in MS Office (Excel, Word).
  • Understanding of Good Laboratory Practice (GLP), Good Manufacturing Practice (GMP) and regulatory frameworks (ISO, FDA) relevant to microbiology labs.
  • Ability to perform method validation or verification, interpret microbiology assay data, trend results, and participate in CAPA or deviation investigations.
