Scientist/Senior Scientist, Stem Cell Therapeutics

110 - Stem Cell Therapeutics · Berkeley, California
Department 110 - Stem Cell Therapeutics
Employment Type Full-Time
Minimum Experience Mid-level

Caribou Biosciences is a clinical-stage biopharmaceutical company founded in 2011 by pioneers in CRISPR genome editing and headquartered in Berkeley, California. The company’s mission is to develop innovative, transformative therapies for patients with devastating diseases through novel genome editing. Caribou leverages its proprietary technologies to develop a wholly owned pipeline of genome-edited, off-the-shelf immune cell therapies, including CAR-Ts and CAR-NKs, for the treatment of multiple different types of cancer. Caribou believes that advanced genome editing is necessary to develop sophisticated cell therapies to treat a variety of malignancies.

Members of the Caribou herd open their minds to new ideas and welcome diverse perspectives. We proudly assert that teams do their best work when their members are personally engaged, their ideas are taken seriously, their contributions are recognized, and their needs are met.


We are seeking a Scientist/Senior Scientist to join our Stem Cell Therapeutics Group.  As part of a highly collaborative, supportive, and friendly team, you will interact closely with other Scientists and Research Associates to drive discovery and development of Caribou’s first iPSC derived NK cell therapy product. You’ll apply your expertise in stem cell biology and immunology to solve the challenge of evaluating how closely iPSC derived NK cells resemble primary NK cells in both phenotype and function, and how to manipulate the differentiation process to produce desirable phenotypes in our NK cell product. You will do this by evaluating CAR construct designs in an NK cell line, as a quick assessment of function, later assessing CAR function into a more complex iPSC derived model.  This is a wonderful opportunity to develop next-generation therapies and advance them into the clinic while growing with a team who are generous with their time, always willing to give advice to help with challenging experiments, and who are there to celebrate your wins.
