The Microbiologist supports the analytical testing operations of a new peptide testing venture, with a primary focus on bacterial endotoxin and sterility testing for peptide products. This role operates within a rigorous quality management environment as the laboratory builds toward ISO/IEC 17025 accreditation, and requires expertise in USP compendial methods and aseptic technique. Success in this role means accurate, defensible test results delivered on time with full documentation integrity.

• Perform bacterial endotoxin testing of peptides using LAL and/or recombinant Factor C (rFC) methods per USP and/or .
• Perform sterility testing by the compendial method per USP (Valiteq ExtenDATE), and/or by a validated rapid alternative method (e.g., BacT/ALERT) per USP .
• Prepare samples, standard endotoxin curves, and controls; calculate endotoxin limits and maximum valid dilution; interpret and report results.
• Conduct method suitability testing for each peptide product, including interference screening for the endotoxin method and bacteriostasis/fungistasis testing for sterility.
• Maintain aseptic technique and ISO‑classified clean‑area conditions during all sterility testing activities.
• Operate, calibrate, and maintain plate reader and related laboratory equipment.
• Document all testing per the laboratory's quality management system and data‑integrity requirements, aligned with ISO/IEC 17025 as the lab works toward accreditation; record results in LIMS and issue test reports.
• Recognize and report out‑of‑specification or nonconforming results, and suppor investigations under supervision.

• Bachelor’s degree in Microbiology, Biology, Biochemistry, or a related life sciences field.
• Valid driver’s license.
• Hands‑on experience performing bacterial endotoxin testing using LAL and/or recombinant Factor C (rFC) methods.
• Hands‑on experience performing sterility testing using Valiteq ExtenDATE and/or by a validated rapid alternative method.
• Working knowledge of USP , , , and , in addition to aseptic technique in ISO‑classified clean areas.
• Familiarity with ISO/IEC 17025 quality management and documentation practices.
• Attention to detail and ability to work both independently and as part of a team.
