This is a hands-on, lab-based position.
Responsibilities:
- Support the discovery and development of therapeutic molecules through hands-on laboratory work.
- Characterize antibodies in high-throughput manner via biolayer interferometry (BLI) and surface plasmon resonance (SPR) based biosensor platforms to determine Yes/No binding, Kinetics and Affinity information.
- Screen antibodies and other antibody-like molecules for off-target binding assessment via BVP ELISA or other poly-specificity/poly-reactivity assays.
- Perform early developability assessment on antibody panels using SPR, DLS, DSF, SEC and ELISA platforms.
- Support other workflows as needed, including fluorescence based binding assays and assay automation.

- Extensive experience in antibody screening including monoclonals, bispecific, and other antibody-like molecules.
- Extensive hands-on experience with ELISA, BLI and SPR based platforms (Carterra, Biacore).
- Basic knowledge of protein production, purification and characterization techniques (including affinity, ion exchange, HIC, DLS, DSF and SEC).
- Proficiency in data analysis software (e.g., GraphPad Prism) and other statistical tools.
- Proactive attitude with a self-starter mindset.
- Strong organizational, communication, and interpersonal skills.
- Strong collaborative skills and interest in working in cross-functional teams and a startup environment.
