Senior Scientist: Bispecifics and Antibody Engineering

We are seeking a results-driven Senior Scientist to join Regeneron's Antibody Engineering team within the Bispecifics and Antibody Engineering Department. In this fast-paced, innovative group, you will design, produce, and characterize next-generation antibody and protein therapeutics across multiple therapeutic areas with a focus on myeloid cell biology. Your work will directly contribute to the pipeline and help build new platform capabilities at a pivotal time for antibody engineering.

As a Senior Scientist, a typical day could require the following:

* Apply molecular and structural biology expertise to independently design innovative multi-specific antibodies with desired potency, selectivity and develop ability.

* Perform molecular and structural-guided design, high-throughput construct generation, and vector engineering using modern software and tools.

* Produce and purify novel and logic-gated alternative format antibodies using mammalian expression systems utilizing an assortment of molecular biology & biochemical techniques (i.e. AKTA systems and other chromatographic columns).

* Characterize binding affinities, binding kinetics & stability.

* Design and implement high-throughput and properly controlled biochemical and cell-based assays (ELISA and Alpha

LISA, flow cytometry binding, phagocytic assays, cell activation and cytolytic assays).

* Troubleshoot bioanalytical and cell-based assay data to inform subsequent iterations.

* Engage program stakeholders to communicate biologic designs with data updates to meet program objectives.

* Clearly convey results to management during cross-departmental meetings and maintain timely, accurate entries using Benchling and research ELN.

This role may be a strong fit If You:

* Have expertise in myeloid, molecular, and protein biology.

* Learn new skills quickly and troubleshoot antibody production and functional assays effectively.

* Excel in data analysis and interpretation while supporting multiple projects simultaneously.

* Competently prioritize efforts to quickly adapt to evolving program directions.

* Possess exemplary organizational, communication, and presentation skills.

* Enjoy collaborating across diverse, cross-functional teams.

To be considered for this role you must have a PhD in molecular biology, cell biology, biochemistry, immunology or a related field with at least one year of relevant experience in academia or industry. Core hands-on experience with cloning, antibody expression in mammalian cell lines, antibody purification (i.e., using AKTA systems), and comprehensive protein characterization is desired; however, we're excited to train motivated learners.

Familiarity with cell-free expression and structural AI/ML-design is preferred but not required.
