Company Summary:

Toran Therapeutics is a privately held, early stage biotechnology company creating an unprecedented drug discovery platform around transporter proteins to discover novel therapeutics. As the molecular gateways of our bodies, transporters are responsible for the flux of all biomolecules into and out of all cells and organelles. As a generally untapped but druggable class of proteins, transporters have been ignored because they are notoriously difficult to work with. Toran is developing novel biological and technological solutions for transporter biology to treat a broad range of diseases.

Toran Therapeutics was founded by Flagship Pioneering, an institute dedicated to the origination and development of first-in-category life sciences companies. Since 2000, Flagship has originated and fostered the development of nearly 100 scientific ventures resulting in $20+ billion in aggregate value, 500+ issued patents, and more than 50 clinical trials for novel therapeutic agents.

Position Summary:

We are seeking a highly motivated scientist or biological engineer with experience in expression, purification, and characterization of proteins. S/he will join an interdisciplinary team to implement and execute new and existing methods for protein biochemistry efforts. We are looking for an enthusiastic, detail-oriented scientist with a passion for mastering protein biochemistry and analytical techniques to bring novel medicines to patients. S/he will be comfortable balancing multiple projects and enjoy working in a pioneering, fast-paced, and collaborative start-up environment, with the opportunity to make a large impact to advance Toran’s mission.
