Engineer/Applied Physicist

TLDR

Build full-stack engineering for organ-scale cryopreservation hardware, spanning electronics, mechanics, and computation with high autonomy and first-principles problem solving.

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’re building an elite team of applied physicists and engineers for true full stack engineering, from electrons to operating systems. Projects will require high degree of autonomy and breadth of skill across electrical, mechanical, and computational design, with a strong emphasis on first principles thinking and a desire to make technology indistinguishable from magic.

    Until is innovating in the field of biology with a focus on organ-scale reversible cryopreservation. We aim to preserve donated organs at subzero temperatures without ice formation, enabling them to be safely rewarming for transplant, while also working towards the larger goal of allowing patients to wait for future cures without losing the possibility of treatment. Our approach combines interdisciplinary expertise to forge solutions that could redefine the boundaries of medicine and organ transplant logistics.
