Quality Assurance (QA) Microbiologist
QA Microbiology is for scientists who are fascinated by the invisible world of microorganisms and want their work to protect people. You are the detective who catches contamination before it reaches the consumer. Highly technical, safety-critical, and globally mobile — especially in pharmaceutical manufacturing.”
About This Role
Ensuring products are free from microbial contamination through testing and audits.
A Day in the Life
You conduct microbiological testing, interpret results, and ensure that manufacturing environments, raw materials, and finished products meet microbiological safety and quality standards.
- Conduct microbiological testing of raw materials, in-process samples, and finished products
- Perform environmental monitoring of manufacturing areas (air, surface, water)
- Prepare and review microbiological test reports and certificates of analysis
- Investigate out-of-specification (OOS) microbiological results and initiate CAPAs
- Maintain culture media, microbiology laboratory consumables, and equipment
- Validate sterilisation processes and microbial testing methods
- Support preparation for GMP and NMRA regulatory inspections of microbiology labs
- Train production staff on microbial contamination prevention (hygiene, gowning)
Work Environment
Microbiological laboratory within a pharmaceutical, food, or cosmetic manufacturing facility. GMP-controlled environment with strict gowning requirements. In Sri Lanka, found at pharmaceutical manufacturers (Hemas, CIC), food exporters, and commercial microbiology testing labs.
Typical hours: 46h/week · WLB score 6/10 · OCCASIONAL overtime
Shift work may be required in 24/7 manufacturing environments. Test turnaround deadlines create periodic overtime.
