Pressing pause on biological time, for those who need it most.
The 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.

The Company
What We Do
We are building reversible cryopreservation technology to solve the organ procurement and matching problem.
Cryopreservation is already essential to modern medicine — powering IVF and life-saving stem cell therapies.
Now, we’re extending this technology to whole human organs — transforming hours of viability into weeks, or months, however long is necessary — so that no donated organ is lost to logistics, and no patient dies waiting.
By solving this immediate need, we de-risk and build the foundation for what comes next: whole-body reversible cryopreservation. We're pausing molecular motion to give patients a bridge to future cures.
