Scientist / Sr. Scientist, Medical Hibernation

Bay Area
Research - Rodent Hibernation /
Full-time /
On-site
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 are seeking a Scientist/Sr. Scientist. Initial responsibilities will include implementing and improving our whole-body perfusion system as well as developing physiological evaluation platforms to assess the viability of vascular systems and organ systems.

Key Responsibilities

    • Implement and modify our whole-body perfusion system, monitor and maintain central physiology parameters (pressure, heart rate, respiratory rate, blood gas parameters etc).
    • Design and implement assays to assess organ, tissue and vascular damage following perfusion and cryopreservation.
    • Work with our team to optimize current perfusion protocol and propose novel perfusion and cryopreservation strategies.
    • Apply and communicate surgical expertise and medical insights to the team.

Qualifications

    • You’ve completed an MD, PhD or DVM, ideally in medical research. 
    • You have demonstrated expertise in rodent surgery.
    • You have demonstrated agency and rapid problem solving capability.  
    • You have demonstrated the passion to implement creative and novel approaches to solve multifaceted problems as they arise. 

What We Offer

    • Opportunity for outsized impact creating the future as an early team member
    • Generous medical, dental and vision insurance coverage
    • Flexible time off and paid holidays
    • Competitive compensation package, including salary and equity
    • 401(k) retirement savings plan
    • FSA and commuter benefits
    • Subsidized lunch daily
$120,000 - $180,000 a year
While this represents our expected range based on market data, final compensation will be determined based on your specific qualifications and may be outside this range. Please keep in mind that the equity portion of the offer is not included in this estimate.
