• Microbiology Investigations & CAPA:
  • Author, review and facilitate high-level, complex microbiological investigations (including sterility failures, adverse bioburden trends and systemic EM excursions)
  • Ensure robust Root Cause Analysis (RCA) is executed and effective CAPAs are implemented
• Risk Management:
  • Participate in contamination control risk assessments (e.g., FMEA, HACCP) to support cleanroom qualifications, VHP cycles and routine environmental monitoring site selection
• Validation & Tech Transfer:
  • Oversee the qualification of microbiological methods (Bioburden, Endotoxin, and Sterility testing) and advanced QC Micro laboratory equipment (e.g., autoclaves, and isolators)
• Regulatory Representation:
  • Act as a technical spokesperson for QC Microbiology during regulatory inspections (e.g., HPRA, FDA) and lead the preparation of inspection-readiness within the QC microbiology laboratory
• Continuous Improvement:
  • Champion the implementation of new technology and digital innovation in the microbiology lab
• Documentation Leadership:
  • Author and pre-approve complex technical documents and validation protocols
