Full 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 We are seeking an experienced and dedicated full-time Research Associate to join our whole organ preservation team. As Research Associate, you will play a vital role in the scientific progress of our research program. The primary focus of this role is on developing organ perfusion protocols, with an emphasis on organ isolation, preservation, and viability evaluation. The person in this role is encouraged to take on significant ownership of specific technical challenges. You will have the opportunity to collaborate with scientists and engineers across the company on variety of methods inspired by first principles of biology, physics, and chemistry.
