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 We are seeking an experienced, motivated and detail-oriented full-time Research Associate to join our hibernation team. In this role, you will contribute directly to advancing our mission by developing and refining whole-body cryoprotectant perfusion protocols. Your initial responsibilities will center on systematic evaluation of perfusion efficiency and post-perfusion organ viability. The person in this role is encouraged to take on significant ownership of specific technical challenges.   You will work closely with scientists, applying fundamental principles from biology, physics, and chemistry to solve complex problems. We value creative engagement and encourage you to explore new ideas, methods, and approaches that can accelerate discovery and optimization.
