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 The Role
We’re building an elite team of applied physicists, engineers, and materials scientists 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 materials design, with a strong emphasis on first principles thinking.

About You

  • Undergraduate degree or equivalent work experience in a scientific discipline (engineering, physics, biology, etc.)
  • Experience with standard lab techniques and equipment
  • Demonstrations of exceptional ability and autonomy in past work

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
