AI Summary

Software engineer who designs and builds the data pipelines, lab automation interfaces, and cloud-based systems powering Until’s biology-focused experiments. Owns projects end-to-end and collaborates across disciplines.

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 time-critical challenge, we’re laying the foundation for medical hibernation: pausing molecular motion to give patients a bridge to future cures.

To achieve our goal, we are assembling an interdisciplinary team to develop perfusion systems, cryoprotectant formulations, controlled-rate freezers, and vitrification and rewarming protocols for human tissue. We are also building out our medical hibernation team to tackle the challenges of whole-body cryopreservation, beginning with rodent models.

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 Software Engineer at Until, you’ll build the computational and infrastructure backbone that enables our science to move faster. You’ll design and implement data pipelines, lab automation interfaces, and cloud-based systems that scale with our experiments. You will own projects end-to-end, collaborate across disciplines, and set a high bar for developing code that scales with the team.
