Assay Development Scientist


About Aura:

At Aura Biosciences, we are developing a new class of therapies to target and destroy cancer cells selectively, while leaving surrounding tissue unharmed – an approach we call molecular surgery.  By safely eliminating cancer locally, we can treat early and transform the lives of people with a wide range of cancers that are poorly managed today.

Our lead program in ocular melanoma is designed to remove cancer cells in the back of the eye as a first-line therapy potentially long before the disease progresses and metastasizes to the liver, where it almost always is fatal. Development of a first-in-class treatment option to selectively destroy cancer cells would create the possibility of a cure in this and other cancers where the disease can be detected early.

Position Summary:

Reporting to the Senior Scientist, the Assay Development Scientist will be responsible to develop, qualify and transfer analytical methods to support biopharmaceutical product development. The incumbent will interact with in-house team and CRO/CMO to ensure timely progress in technology development, as well as documentation and smooth technology transfer.
