Assay Development Research Associate/Sr. Research Associate

Research & Development Cambridge, Massachusetts


Company Overview

Repertoire Immune Medicines is a clinical-stage biotechnology company working to unlock and direct the remarkable power of the human immune system to prevent or treat cancer, as well as autoimmune and infectious disease.  The company is founded on the belief that the repertoire of T cell receptor (TCR)-antigen codes that drive health and disease represents one of the greatest opportunities for innovation in medical science.  Repertoire scientists created and developed the DECODE and DEPLOY suite of technologies, which allow in-depth characterization of TCR-antigen pairs, and the ability to rationally design and develop novel targeted immune medicines.

From its sites in Cambridge, Mass., and Zurich, Switzerland, Repertoire’s team of more than 120 is creating a new category of immune medicines enabled from its DECODE discovery platform.  The company’s first product in the clinic is a novel multiclonal T cell therapy consisting of T cells derived from the peripheral blood, activated against a curated set of antigens, and armed with a proprietary cytokine.  Repertoire is in clinical-stage immuno-oncology development today, targeting metastatic solid tumors.  In the field of autoimmunity, Repertoire is currently using its proprietary platform to discover novel epitopes and TCRs from patients with type 1 diabetes.  The company is also using its DECODE platform to discover infectious disease antigens and responding T cell clones.

Role Overview

We are seeking a Research Associate/Sr. Research Associate to join our assay development team in Repertoire’s platform technology group.  The primary role of the position is to develop and implement molecular assays and workflows as part of our DECODE platform, which supports discovery programs and translational sciences.  We are looking for an enthusiastic team player who will thrive in an accelerated, dynamic, and highly collaborative environment.  The successful candidate will work as part of a cross-functional team of immunologists, molecular biologists, and protein scientists to develop and verify assays, explore new technologies, and drive process scale-up.
