Under guidance from the manager, you will work effectively with cross-functional project teams to generate and validate therapeutic proteins and tool molecules, including monoclonal and bispecific antibodies, immunocytokines, and other complex biologics, to support preclinical development across multiple therapeutic areas.

What You'll Do

• Perform protein purification and characterization for quality and document work in electronic lab notebook and various informatics systems to support the preclinical development of biopharmaceutical programs across multiple therapeutic areas.
• Prepare technical reports, summaries, and check in protein samples into the sample bank.
• Use good oral and written communication skills to relay scientific data and update collaborators of purification status and challenges.
• Actively participate in group meetings, present results, interpret data, draw conclusions and propose next steps for the presented work.
• Maintain awareness of cutting-edge technical developments and apply these where possible to improve work quality and efficiency.

What We're Looking For

• Bachelor's degree in Biology, Biochemistry, Chemistry or related field with at least 2+ years of relevant experience; or Master's degree with above-listed characteristics.
• Direct hands-on experience in purifying and characterizing a variety of recombinant proteins, particularly monoclonal antibodies and complex biologics (bi/multi-specific antibodies).
• Hands-on experience in purification techniques including affinity, ion exchange, size exclusion, hydrophobic interaction chromatography using AKTA Avant/Pure.
