Job Description

Until is a moonshot company building a “pause button” for biology. Our near-term focus is organ-scale reversible cryopreservation: preserving donated organs at subzero temperatures without ice formation, then rewarming them uniformly for transplant. By solving this grand challenge, we’re laying the foundation for whole-body reversible cryopreservation, giving patients a bridge to future cures.

To achieve our goal, we are assembling an interdisciplinary team to develop perfusion systems, cryoprotectant formulations, and vitrification and rewarming hardware.

We envision a future where no transplantable organ is lost to logistics, and no terminal diagnosis is final because patients can safely wait for future medicine to arrive.

About the Role

You will be part of a team that designs, builds, and characterizes new technologies that form the foundation of organ-scale reversible cryopreservation. We are seeking a Scientist/Senior Scientist to join our team. As a (Sr.) Scientist in Renal Biology, you will be an integral member of the team advancing cryopreservation formulations. You will design, execute, and analyze high throughput experiments focused on kidney biology. You will establish experimental approaches to characterize toxicity and permeability of new cryoprotectant solutions using kidney cell cultures and 3D in vitro kidney models. Your work will establish novel approaches of using predictive 2D and 3D models for toxicity assessment to help enable human-sized kidney preservation and help bridge patients to future cures.
