Job Description

The Microbiology QC Senior Specialist is a key technical leadership role providing high-level oversight of the QC Microbiology programs and quality systems. The role focus is on leading complex microbiology investigations, coordinating cleanroom qualification and Environmental Monitoring/Utilities program strategies, executing advanced technical reviews and driving technological innovation (e.g., rapid micro methods). The role ensures compliance with sterile manufacturing standards (such as Annex 1), coordinates regulatory audit responses and supports method qualification and technology transfers.

Bring energy, knowledge, innovation to carry out the following:

Technical Oversight of Programs

• Provide advanced technical oversight of the Environmental Monitoring (EM) and clean utilities (WFI, gases, clean steam) programs, ensuring alignment with current global regulatory expectations (such as EU Annex 1).

Technical & Peer Record Review

• Perform critical technical review and secondary verification of complex laboratory records, validation data packages, method transfer protocols and high-impact testing records (e.g., sterility and endotoxin assays) to guarantee complete compliance.

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
