We are looking for highly motivated Associate Scientists, to join Regeneron’s Early Career Exploration Program (ECEP). This program is a full-time opportunity for former Regeneron interns, graduating with a BS in biology, biochemistry, biophysics, chemistry, or related field to find a full-time opportunity at Regeneron post-graduation.

The ECEP Experience:
Participants will be placed in assignments 3-6 months in length, covering for colleagues on leave of absence, and can have opportunities to explore multiple R&pD functions. The program runs up to 2 years before participants are expected to find permanent placement. This program is intended to be a small cohort, aimed at building a strong entry-level talent pipeline for Regeneron R&pD. Participants will have a centralized manager guiding them throughout their journey, providing them with advice, mentorship and other developmental opportunities.
We hope you are excited by the opportunity to work with numerous functional groups to come up with innovative approaches to tackle some of the most challenging therapeutic discovery projects being pursued at Regeneron.
