Scientist, Cryopreservation & Cell Storage

Cambridge, MA · Science/Research
Company Description

Rubius Therapeutics is a clinical-stage biopharmaceutical company developing a new class of medicines called Red Cell Therapeutics™. Our proprietary RED PLATFORM® was designed to genetically engineer and culture Red Cell Therapeutics™ that are selective, potent and off-the-shelf allogeneic cellular therapies for the potential treatment of several diseases across multiple therapeutic areas. Our therapies can potentially be used to kill tumors in cancer and to regulate the immune system for the treatment of autoimmune diseases. We are currently enrolling patients in a Phase 1/2 clinical trial of RTX-240, an allogeneic cellular therapy for the treatment of patients with relapsed/refractory or locally advanced solid tumors or relapsed/refractory acute myeloid leukemia (AML). Additionally, we plan to file an IND for RTX-321 for the treatment of HPV-positive tumors by year-end.
We are proud of our passionate, high-performance culture – one based on a set of values that are the cornerstone of who we are and how we hold ourselves accountable. Founded in 2013, we are headquartered in Cambridge, MA, and our manufacturing facility in Smithfield, RI was named 2020 Top 5 Best Places to Work in Rhode Island among medium-sized companies by Providence Business News. We are currently expanding across all functions within the organization. Red blood cells are no longer just for carrying oxygen.
