- Execute analytical techniques including LCMS, AEX and RP-HPLC purity/identity testing, UV (A260) concentration/assay, Karl Fischer water content, pH, and bacterial endotoxin (LAL) testing.
- Record raw data, calculations, and results in real time in compliance with good documentation practices (GDP).
- Support investigations (OOS, OOT, deviations) by providing accurate data, reviewing raw data trends, and performing confirmatory/re-test work.
- Monitor sample hold times; promptly communicate any hold-time risk, atypical result, or equipment issue impacting batch progression.
- Maintain a clean, organized, GMP-compliant lab bench/work area (including 5S).
- Communicate effectively during shift handoff to ensure continuity of testing and batch status.
Requirements:

- Hands-on experience with LCMS, AEX-HPLC, RP-HPLC/UHPLC, Karl Fischer titration, and/or LAL/endotoxin testing.
- Experience with in-process (real-time) testing in a manufacturing-adjacent QC lab.
- Knowledge of cGMP and ICH laboratory requirements; proficiency with analytical instrumentation and test method validation/transfers.
