About This Role

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. 

About the Role

As a People Operations Associate, you will play a central role in shaping Until’s employee experience as we scale. You’ll work across recruiting, onboarding, performance management, benefits, and office operations—supporting both day-to-day execution and the development of scalable people systems that enable a high-performing team.

This is a hands-on role suited for someone who thrives in fast-moving, early-stage environments and enjoys building structure where little exists.
