About this opportunity

At Regeneron, we use science and innovation to develop life-changing medicines for people with serious diseases. We are seeking a Senior Associate Scientist to join our discovery research team at Regeneron Cell Medicines. In this role, you will perform immunological functional assays to analyze genetically engineered human primary T cells (CAR-T or TCR T cells), supporting both early discovery programs and late-stage development programs' nonclinical studies that inform regulatory submissions.

This position offers the opportunity to work hands-on in a fast-paced laboratory environment, contributing to the preclinical research and development of next-generation cell therapies.

When & where:

Shift Requirements: Full-time, standard business hours, with flexibility to support a fast-paced research environment

Location: On-site laboratory setting

Flexibility & travel: Minimal to no travel; consistent on-site presence required to support ongoing experiments and project timelines

What you'll do:

Contribute to preclinical research and development of CAR/TCR T cell therapies in solid tumor indications

Characterize genetically modified primary human T cells via immunophenotyping using multi-color flow cytometry and molecular assays (PCR, library preps for NGS, RNA-Seq)

Develop and perform immunological functional assays to assess immune cell activation, anti-tumor cytotoxicity, proliferation, and cytokine secretion to evaluate the efficacy of CAR and TCR-based T-cell therapeutics

Design experiments independently and contribute to overall project direction

Maintain an electronic lab notebook and thoroughly document experiment results

Review and present research data to the functional team

The environment and physical rhythms of this role:

This is a hands-on, on-site laboratory role in a fast-paced research setting. The role requires the ability to perform bench work involving fine motor tasks (e.g., pipetting, cell culture manipulation), extended periods of standing, and use of standard laboratory equipment.

Flexibility to adapt quickly to new research areas, shifting priorities, and evolving experimental techniques is required.

Let's find out if we're a fit:

Must-haves:

BS/MS in immunology, cell biology, or a related field, with 3+ years of relevant experience

Experience working in a biotech/pharmaceutical industry

Strong understanding of immunology and cancer biology

Extensive experience in primary human immune cell isolation techniques and mammalian cell culture, including culture of primary human T lymphocytes

Demonstrated experience with in-vitro immunological studies and development of functional T cell assays using techniques such as multi-color flow cytometry, ELISA, and cytotoxicity assays

Preferred / nice-to-haves:

Experience with gene delivery into T cells or tumor cells using lentiviral vector transduction, CRISPR/Cas9 editing, and mRNA electroporation

Experience with standard molecular biology techniques, including PCR, qPCR, Westerns, and library preps for NGS/RNA-Seq

Thrive today. Grow tomorrow.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
