Senior Scientist/Scientist PK/PD Modeling Specialist

Obsidian Therapeutics is a biotechnology company developing next-generation cell and gene therapies with using synthetic biology approaches. Based upon founding work on destabilizing domains by Professor Thomas Wandless, a leading researcher in chemical and systems biology, Obsidian’s lead programs are engineered T cell products (CART and TCR T cells) that utilize small molecule drugs to control function for enhanced safety and efficacy. We are looking for a highly talented, flexible, collaborative, dynamic leader to create a key functional area to translate our research efforts to the clinic.

Obsidian products use FDA-approved small molecule drugs to trigger the production of therapeutic proteins within living cells. The qualified candidate will use his/her PK/PD modeling expertise to inform study design and interpretation in pre-clinical mouse models of anti-tumor cell therapy. A thorough understanding of small molecule pharmacology is essential for this individual to build and refine preclinical experimental designs that can be used for clinical translation.

This role is a unique opportunity to be a partner and scientific contributor in a well-funded startup with blue chip investors, field-leading founders and advisors, and a highly experienced startup team. You will help us build a dynamic, passionate, collaborative, transparent and successful organization focused on delivering transformative therapies in oncology and other areas of greatest clinical need. Located in an energetic environment in the heart of Cambridge, Obsidian is an equal opportunity employer offering a competitive salary and benefits package.
