What You’ll Bring to the Team
Deep hands-on experience designing, expressing, and optimizing monoclonal antibodies, with demonstrated understanding of Fc structure–function relationships (effector function, stability, manufacturability).
Proven experience with bispecific antibody architectures, including but not limited to:
Knob-in-hole, CrossMab, common light chain, or similar
Chain pairing control and mispairing mitigation
Experience generating and optimizing stable mammalian cell lines (CHO preferred):
Vector design, promoter/selection strategies
Clone screening, productivity optimization, and stability assessment
Strong understanding of transient vs stable expression tradeoffs and when to deploy each during platform development.
Experience improving expression yields and product quality through sequence, vector, and host engineering.
Demonstrated ability to build, improve, and standardize antibody generation workflows, not just execute existing SOPs.
Experience developing high-throughput or semi-automated workflows for expression, purification, and screening.
Strong understanding of platform robustness, reproducibility, and cost drivers.
Hands-on experience with antibody characterization methods, such as
SEC, CE-SDS
Binding kinetics (BLI or SPR)
Basic biophysical profiling (DSF, DLS)
Strong mechanistic understanding of antibody biology, structure, and expression bottlenecks
Experience designing platforms that support multiple antibody modalities (mAbs, bispecifics, Fc-engineered variants)
A track record of successful and creative method development
Qualifications
PhD in Cell Biology, Biochemistry, or a closely related field
5+ years of experience in protein sciences
5 years of management experience
Hands-on experience working with antibody expression and purification
Experience with liquid-handling systems and automation is a plus
Familiarity with Python or equivalent programming languages is a plus
