Quality Control (QC) Associate Scientist

Role Description

We are seeking a detail-oriented and proactive Associate Scientist to join our Protein Department QC group. This role is responsible for performing analytical characterization and quality control testing of recombinant proteins generated from high-throughput production workflows.

The successful candidate will play a critical role in ensuring protein identity, purity, and overall quality through robust analytical methodologies. This position operates in a data-driven and quality-focused environment where accuracy, reproducibility, and data integrity are essential. The ideal candidate will have hands-on experience with protein analytical techniques and familiarity with laboratory data management systems such as ELN, LIMS, or equivalent platforms.

Key Responsibilities

• Perform routine and non-routine analytical and QC testing to evaluate protein identity, purity, and quality attributes.
• Execute a range of protein characterization assays, including:
• HPLC / UPLC (e.g., SEC, RP, IEX)
• Capillary Electrophoresis (CE, iCE/cIEF)
• SDS-PAGE
• Western blot
• LC-MS
• Endotoxin assays
• Prepare samples, reagents, buffers, and standards in accordance with established protocols and assay requirements.
• Perform sample preparation workflows, including use of automated liquid handling systems where applicable.
• Analyze, interpret, and document experimental data in ELN, LIMS, or equivalent systems, ensuring compliance with data integrity standards (e.g., ALCOA+ principles).
• Support method troubleshooting and optimization, ensuring assay robustness, reproducibility, and consistency across runs.
• Maintain laboratory instruments and ensure proper calibration and performance, supporting compliance with quality and safety standards.
• Collaborate with cross-functional teams (e.g., protein production, process development) to support project timelines and deliverables.
• Contribute to continuous improvement initiatives, including method refinement, workflow efficiency, and data quality enhancement.

Qualifications

• BS or MS in Biochemistry, Analytical Chemistry, Biotechnology, or a related field with 2+ years of relevant experience in protein analytical characterization or QC.
• Hands-on experience with protein analytical techniques such as HPLC/UPLC, CE, SDS-PAGE, Western blot, LC-MS, or endotoxin assays.
• Familiarity with protein characterization workflows, including purity, aggregation, and identity analysis.
• Experience with laboratory data systems (ELN, LIMS, or similar) and strong documentation practices.
• Strong attention to detail and commitment to data integrity, accuracy, and reproducibility.
• Experience in a CRO/CDMO or regulated QC environment is preferred.
