• Demonstrated hands‑on expertise in automated liquid handling platforms and associated software programming.
• Proficiency in scripting languages (Python, R, or VBA) for data analysis, workflow automation, or system integration.
• Deep knowledge of QC analytical techniques including mass spectrometry, chromatography, electrophoresis, bioassay, or ELISA.
• Proven ability to work independently, design scientifically sound studies from broad objectives, and drive projects to completion.
• Level will be determined based on qualifications at the time of offer.

• PhD in Chemistry, Biochemistry, Biology, or a related field.
• Previous experience working in a cGMP or cGLP regulated environment.
• Familiarity with Cellario, Venus (Hamilton), or OneLab (Andrew+) automation platforms.
• Experience developing and executing technology transfer plans across QC or partner functions.

Ability to work in a laboratory environment, including standing for extended periods and handling laboratory equipment.

This role operates in a GMP analytical laboratory. Appropriate gowning and PPE are required in designated areas.
