Scribe Therapeutics is a molecular engineering company focused on creating best-in-class in vivo therapies that permanently treat the underlying cause of disease. Founded by CRISPR inventors and leading molecular engineers Benjamin Oakes, Brett Staahl, David Savage, and Jennifer Doudna, Scribe is overcoming the limitations of current genome editing technologies by developing custom engineered enzymes and delivery modalities as part of a proprietary, evergreen CRISPR by Design™ platform for CRISPR-based genetic medicine.


We are seeking a highly passionate and motivated toxicologist to join us in our quest to bring the next generation of CRISPR-based therapeutics into IND enabling framework. The current role is for a Director/Senior Directory of Toxicology. The candidate should have a passion for managing safety pharmacology and toxicology aspects of the IND enabling studies that will bring gene editing modalities into first-in-human study.

The candidate will have numerous opportunities for professional growth in a rapidly growing biotechnology start-up, which includes growing into a cross-functional leadership role of increasing responsibilities that spans across the pipeline, and the ability to publish highly impactful work in peer reviewed journals. 


Key Responsibilities:
