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 quantitative predictors that are data hungry and require precision measurement. This role will be instrumental in collecting high quality data from a variety of experimental devices.

About You

  • Experience with standard lab techniques and equipment
  • Commitment to collecting high quality data

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

Why work at Until

  • Work Environment: On-site in San Francisco (HQ). The work spans "the edge of physics, biology, and engineering" – from quantum-level simulations to handling real organs. Culture emphasizes "hard problems", rigor, and speed.
  • Culture: Flat hierarchy, promotion on merit, "proof of work" over credentials. Team includes people from top universities and self-taught scientists alike.
  • Benefits: Comprehensive medical/dental/vision, 401(k) via Guideline, unlimited PTO, paid parental and disability leave, on-site fitness center, catered lunch and dinner, plus snacks.
  • Engineering & Science: Opportunity to work on cutting-edge cryobiology, nanotech, polymer chemistry, and high-throughput automation. The company uses AI tools in hiring but makes final human decisions.
