Hibernation Rodent Perfusion Intern (Rodent ECMO / Whole-Body Recovery) — Evening/Night Shift

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. 

We’re seeking a highly detail-oriented intern to support rodent ECMO perfusion and whole-body function recovery experiments. This is a hands-on role at the center of live perfusion operations, where precision, focus, and rapid response directly impact outcomes.

The most important part of this job is being the dedicated second set of hands/eyes during late-night perfusions—continuously scanning for critical failure modes and catching small issues before they cascade. You’ll work closely with the experiment lead, handling anesthetized animals gently and accurately while monitoring multiple physiological and circuit parameters in parallel.

This environment changes fast. Success requires strong situational awareness, disciplined documentation, and the ability to stay fully alert and effective during long late-night windows.
