Job Description

Want to help drive a revolution in synthetic biology? Many synthetic biology companies aim to enable humans to thrive sustainably in a resource-limited world. But despite tremendous breakthroughs in reading and writing genetic diversity, the ability to measure the function of those changes hasn't scaled.
