Job Details

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

One of the key outstanding challenges in the field has been the rewarming problem: how do we rapidly and uniformly rewarm large samples to press play on cryopreserved biology? One of the key ingredients is building N‑of‑1 electrical systems. Doing so requires a fast paced, scrappy team of electrical engineers and physicists who want to make technology indistinguishable from magic.

About You

• Track record of exceptional engineering abilities

Preferred Qualifications

• Experience working at a startup
• 3+ years relevant experience/graduate degree in electrical engineering
• Experience with high voltage systems
• Experience with induction heater design
• Experience with HF PCB bringup
• Experience with mixed signal circuit simulation

Benefits

• Opportunity for outsized impact creating the future as an early team member
• Generous medical, dental and vision insurance coverage
