Quality Control (QC) Microbiologist
QC Microbiologist is for science graduates who are fascinated by microbiology and want their work to directly protect public health. You will test, identify, and investigate the microbial content of products that people consume or use medically. Technically demanding, safety-critical, and globally recognised in pharmaceutical and food manufacturing.”
About This Role
Tests industrial products for microbial contamination to ensure safety and compliance with international standards.
A Day in the Life
You perform microbiological quality control testing on products, raw materials, and manufacturing environments to verify compliance with microbiological specifications and regulatory standards.
- Conduct Total Viable Count (TVC), yeast and mould, pathogen testing on products
- Execute environmental monitoring swabs and air sampling in manufacturing areas
- Prepare and pour microbiological culture media following pharmacopoeial standards
- Read, record, and interpret microbial colony counts and identification results
- Investigate atypical or OOS microbiological results
- Maintain sterility and contamination control in the microbiology laboratory
- Prepare documentation for batch release based on microbiological results
- Calibrate and maintain lab equipment (autoclaves, incubators, biosafety cabinets)
Work Environment
GMP microbiological laboratory in pharmaceutical, food, or cosmetics manufacturing. Similar to QA Microbiologist but more focused on routine testing execution than quality system oversight. In Sri Lanka, found at pharmaceutical manufacturers and food export companies.
Typical hours: 45h/week · WLB score 6/10 · OCCASIONAL overtime
