Data Scientist

About This Role

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

As a Data Scientist at Until, you’ll own the full lifecycle of experimental data from generation in the lab to processing, analysis, and visualization. You’ll build the infrastructure and pipelines that move data reliably from instruments to insight, designing reproducible workflows and tools that help the team explore results quickly and clearly. You’ll work closely with scientists and engineers, setting a high bar for data integrity and usability across the team.
