Scientist/Senior Scientist, Vector Process Development

TCR² Therapeutics Inc. is an immuno-oncology company developing novel cancer therapies that unleash the full signaling power of complete T cell receptors (TCR). TCR² has developed a unique proprietary TRuC™ platform which can reprogram the natural TCR complex to recognize specific antigens found on tumors where they elicit rapid killing of cancer cells. The company has demonstrated activity against both hematological and solid tumor targets in preclinical models and believes its TRuC™-reprogrammed T cells will serve as the engine for important therapies.  TCR² was founded by MPM Capital and has scientific operations in Cambridge, MA to leverage best-in-class technologies and nucleate top-tier academic laboratories around the world.

The successful candidate will join the Process Development group in the production and optimization of lentiviral vectors, execution of upstream and downstream process experiments, and participation in the evaluation of new technologies in the development of a robust and scalable manufacturing process.
