• Regulatory Rigor: Ensure all testing, documentation, and data tracking fully comply with current Good Manufacturing Practices (cGMP) and Good Laboratory Practices (GLP).

Qualifications & Requirements
• Education: Bachelor's degree in Chemistry, Biochemistry, or a closely related scientific field.
• Experience:
oMinimum of 3-5 years of hands-on experience within a pharmaceutical industry environment (or an equivalent combination of advanced education and experience).
oCore experience handling high-volume raw material sampling and stability tracking.
• Technical Skills:
oProven proficiency with chromatography software and hardware (HPLC/GC/UPLC).
oFamiliarity with fundamental laboratory tools: balances, pipettes, pH meters, and IR/UV systems.
• Soft Skills: Strong organizational aptitude, meticulous record-keeping habits, and the communication skills required to present data trends to operational management. Equal Opportunity Employer / Disabled / Protected Veterans
