Job description

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 You

  • Track record of exceptional engineering abilities
  • Deep understanding of heat and mass transfer principles
  • Experience designing fluidic systems for perfusion/heat exchangers
  • High degree of autonomy across full engineering stack: electromechanical design and fabrication, control software, physical modeling
  • Desire to join a fast-paced, scrappy engineering team

    • Preferred Qualifications

  • 3+ years experience/graduate level in Mechanical Engineering, Physics, or equivalent
  • Experience with organ perfusion in a research or clinical context
  • Experience working in a startup

    • Benefits

  • Opportunity for outsized impact creating the future as an early team member
  • Generous medical, dental and vision insurance coverage for employees and their dependents
  • Flexible time off and paid holidays
  • Competitive compensation package, including salary and equity
  • Access to a 401(k) retirement savings plan
  • FSA and commuter benefits
  • Subsidized lunch daily
