Summer-Fall 2026 Co-Op - Cell Therapy and Immuno-oncology

Sanofi • Cambridge, MA

1d • Onsite

About The Position

We re-engineer immune cells to selectively kill the tumor cells in cancer patients. Immune cells will function as living drugs and in favorable situations expand and exert a strong anti-tumor response. Similarly, they are bound by the same laws that endogenous human cells are, such as exhaustion by tumor-produced factors, abnormal tumor vessels, and other obstacles that a suppressive tumor microenvironment poses. We try to remove barriers to the success of cell-based therapies in our group. The cell therapy Co-op will work hands-on in the lab in developing assays and techniques to mimic the tumor microenvironment and testing antibodies and biomaterials (e.g., nanoparticles) that alter the immune system in favor of tumor cell eradication. As part of a newly established team, the Co-op will have the opportunity to make significant contributions to the research and development on a daily basis. The ability to learn quickly, work on multiple assignments, and effectively document scientific data are key components of the role.

Requirements

• Currently enrolled and pursuing a bachelor's or master's degree in biology, chemistry, immunology, pharmaceutical Sciences, bioengineering, biomaterials, biochemistry, or related field at an accredited 4-year college or university with the expectation that you will complete your current degree by the Spring of 2028
• Must be enrolled in an accredited college or university throughout the duration of the co-op/internship
• Must be able to relocate to the office location and work 40hrs/week, Monday-Friday, for the full duration of the co-op/internship
