• Develop and optimize protein purification schemes for engineered antibodies using computer-interfaced chromatography systems (e.g., AKTA or similar) utilizing a various chromatographic techniques
• Characterize proteins using biophysical and analytical methods including SEC-MALS, DLS, SDS-PAGE, and analytical SEC
• Contribute to the design and engineering of bispecific antibodies and novel fusion proteins to achieve desired activity, binding specificity, and manufacturability
• Manage all aspects of protein production activities at CRO
• Actively contribute to project strategy and experimental design, and regularly present findings at team meetings
• Document experimental work clearly and completely in electronic lab notebooks and technical reports

Who You Are

You’re a hands-on protein biochemist with deep expertise in purification and biophysical characterization. In addition to performing benchwork yourself, you have experience overseeing protein production at CROs and bring strong operational and organizational skills to the table.

• Strong analytical and biophysical skills, including DLS, SEC-MALS, SDS-PAGE, and SEC
• Experience designing antibody-based formats such as bispecifics and fusion proteins
• Track record of managing CRO relationships and external protein production
• Strong organizational skills and attention to detail
• Excellent communication and data presentation skills

Preferred Skills

• Experience designing protein expression constructs at the DNA level
• Experience with bioconjugation
