CSBio is a peptide contract manufacturer founded in 1993, serving research organizations and pharmaceutical companies worldwide with automated synthesizers and high quality cGMP peptides. We operate cGMP peptide production facilities in Menlo Park, CA, and passed an FDA inspection in 2017 that recommended us for commercial drug substance manufacturing. In 2023, we added cGMP clinical production capacity in Milpitas, CA.

Position Summary

CSBio is seeking a detail-driven Microbiology Technician to join our QC Microbiology laboratory at our Milpitas facility. You will primarily perform bacterial endotoxin and bioburden testing on peptide intermediates, APIs, and drug products, with a focus on our GMP programs.

•   Bioburden testing: Perform microbial enumeration and tests for specified microorganisms (USP <61> / <62>) on raw materials, intermediates, and finished product.

•   Monitoring support: Assist with environmental monitoring of cleanrooms and water-system monitoring; read, enumerate, and record microbial growth.

•   cGMP documentation: Record raw data and results in worksheets and LIMS per cGMP and ALCOA+ data-integrity practices; support OOS/OOT investigations and deviations.

•   Clinical batch support: Support timely testing and release of API and clinical batch products to production timelines.

•   Lab operations: Prepare and quality-check media and reagents; maintain aseptic technique, equipment, and laboratory supplies; and perform other QC micro duties as assigned.

Why This Role

•   Good manual dexterity for precise pipetting and sample handling.

Nice to haves:

◦    Hands-on experience with bacterial endotoxin (LAL) testing and/or bioburden / microbial enumeration methods (USP <85>, <61>, <62>).

◦    Exposure to a cGMP, pharmaceutical, biotech, or other regulated laboratory environment.

◦    Familiarity with environmental monitoring, water-system monitoring, or media preparation.

◦    Experience with LIMS and electronic data-recording systems, and understanding of data integrity (ALCOA+) and good documentation practice (GDP).
