About Until

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 challenge, we are 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. 

Role Overview

This is a senior leadership role responsible for shaping Until’s legal, IP, and risk posture as the company moves toward the clinic. The Head of Legal will act as a strategic partner to the executive team, influencing core technical, commercial, and regulatory decisions.
