At Regeneron, we use science and innovation to develop life-changing medicines for people with serious diseases. We are seeking an Associate Scientist to join our Ophthalmology group, supporting the development of therapies for ocular immune and inflammatory diseases. In this role, you will engage in hands-on research across cell biology, immune-focused assays, and disease-relevant experimental models while collaborating with a team working across multiple preclinical programs.

This position offers the opportunity to contribute to a fast-growing, science-driven organization making a meaningful difference to patients worldwide.

When & where

• Location: Tarrytown, NY
• Work model/flexibility: Onsite

Discover your role

• Handle and care for mice, including procedures such as injections, colony management, and blood/tissue sample collection.
• Perform tissue dissection and cell isolation from ocular and other tissues for downstream analysis.
• Maintain, expand, and/or treat cells in vitro, using established cell lines and primary human and mouse cells.
• Perform immunoassays and molecular biology assays such as ELISA, Western blot, DNA/RNA extraction, and multiplex platforms such as MSD and Luminex/CBA.

• Experience with mammalian cell culture, including cell lines and primary cells.
• Experience with immunoassays such as ELISA, MSD, or Luminex; Western blot; or DNA/RNA extraction.
