Job title: Summer Intern 2025 - Cell Therapy

Location: Cambridge, MA

About the Job

Are you ready to shape the future of medicine? The race is on to speed up drug discovery and development to find answers for patients and their families. Your skills could be critical in helping our teams accelerate progress.

Our team re-engineers immune cells to adaptively transfer to patients to selectively kill the tumor cells. 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 intern will work hands-on in the lab, 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.

We are an innovative global healthcare company with one purpose: to chase the miracles of science to improve people’s lives. We’re also a company where you can flourish and grow your career, with countless opportunities to explore, make connections with people, and stretch the limits of what you thought was possible. Ready to get started?
