Phage Production - QC Technician

Join our team as a Phage Production - QC Technician responsible for performing critical in-process quality controls throughout the bacteriophage production lifecycle. Working under GMP-like conditions, you will execute a range of microbiological and analytical tests, including bacterial and phage titrations, product sterility assessments, and endotoxin level measurements. This role requires meticulous adherence to Standard Operating Procedures (SOPs), rigorous aseptic techniques within a BSL-2 laboratory environment, and the ability to work efficiently, independently, and with a high degree of organization as part of a dedicated team.

Key Responsibilities:

Quality Control & In-Process Testing:

• Perform routine bacterial and phage titrations according to established SOPs to monitor culture viability and phage concentration.
• Conduct sterility testing on in-process samples and final product to ensure absence of contamination.
• Measure endotoxin levels in samples using appropriate methodologies.
• Execute all assigned in-process quality control tests accurately and in a timely manner, following strict protocols.
• Analyze and interpret QC test results, promptly reporting any out-of-specification or unexpected findings.

Stock Management (as related to QC activities):

• Prepare, manage, and maintain bacterial host strains and bacteriophage reference stocks used for quality control testing according to defined procedures.
• Ensure proper labeling, storage, and traceability of all QC samples and reference materials.

Equipment & Environment:

• Operate, monitor, and perform routine checks on laboratory equipment relevant to QC testing, including incubators, centrifuges, biological safety cabinets (flow cabinets), spectrophotometers, plate readers, and equipment for endotoxin testing.
• Work consistently under strict aseptic conditions within a BSL-2 laboratory environment to ensure test integrity and prevent contamination.
• Maintain the cleanliness and organization of the QC laboratory space.

Documentation & Compliance:

• Maintain an accurate and detailed records of all performed QC activities, complying with GMP-like documentation practices.
• Ensure all activities are performed in compliance with internal quality standards and relevant regulatory guidelines.

• Education: Minimum "Bac+3" (e.g., Licence Professionnelle, Bachelor's degree) in Microbiology, Biotechnology, Biology, Quality Control, or a closely related scientific field.
• Experience: 2-3 years of relevant hands-on laboratory experience, ideally in a Quality Control microbiology laboratory, biotechnology, or pharmaceutical (including GMP) setting.

Essential Skills & Knowledge:

• Demonstrated proficiency in core microbiology techniques, particularly strict aseptic technique, bacterial culturing, and enumeration methods.
• Practical experience with microbiological QC assays (e.g., bioburden, sterility testing, endotoxin testing, microbial identification, titrations).
• Proven ability to follow complex protocols (SOPs) precisely and consistently.
• Strong attention to detail and meticulous record-keeping/documentation skills (experience with GMP-like documentation is essential).
• Ability to work autonomously, efficiently, and manage tasks effectively with a high degree of organization.
• Proficiency in English (both written and spoken) is a plus.
