• Develop scalable and high-throughput analytical approaches to support increasing sample volume and rapid experimental iteration.
• Troubleshoot method performance, resolve analytical challenges, and improve assay reliability, throughput, and data quality.
• Support interpretation and integration of data generated by third-party laboratories, including LC-MS and other specialized protein characterization techniques.

High-Throughput Workflow Development

• Develop and implement high-throughput protein analytical workflows to support increased sample volume and rapid experimental iteration.
• Optimize sample preparation, assay design, and analytical workflows to reduce manual handling and improve operational efficiency.
• Partner with cross-functional teams to identify bottlenecks and build scalable analytical solutions that support evolving R&D needs.

Collaboration and Technical Leadership

• Serve as the technical lead for protein analytics, providing guidance on method selection, data interpretation, and analytical strategy.
• Support method standardization, tech transfer, and adoption of best practices across protein analytical workflows.
• Partner closely with Biology, Chemistry, and Process Engineering teams to define analytical needs and translate them into effective testing strategies.
• Communicate analytical results, limitations, and recommendations clearly to technical and cross-functional stakeholders.
• Coordinate with external laboratories and vendors for specialized protein characterization, including review and interpretation of third-party data.

Required Qualifications

• B.S. or M.S. in Chemistry, Biochemistry, Analytical Chemistry, or a related scientific discipline.
• 7+ years of relevant analytical laboratory experience
• Hands-on experience developing, optimizing, and executing HPLC methods for proteins, peptides, or other biomolecules.
• Experience with complementary protein analytical techniques such as UV-Vis, plate-based assays, SDS-PAGE, or similar methods.
• Demonstrated ability to troubleshoot analytical methods, interpret data, and communicate results across technical teams.

Preferred Qualifications

• Experience with LC-MS for protein, peptide, or biomolecule characterization, including TOF, QTOF, or Orbitrap platforms.
• Prior experience scaling protein analytics into higher-throughput laboratory environments or supporting development programs with increasing sample demand.
• Familiarity with protein quantification, purity, aggregation, or stability assays.
• Experience qualifying or validating analytical methods in a research or process-development environment.
• Experience working with external laboratories, instrument vendors, or contract testing partners.
