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 You

• Track record of exceptional engineering abilities
• Deep understanding of heat and mass transfer principles
• Experience designing fluidic systems for perfusion/heat exchangers
• High degree of autonomy across full engineering stack: electromechanical design and fabrication, control software, physical modeling
• Desire to join a fast-paced, scrappy engineering team

Preferred Qualifications

• 3+ years experience/graduate level in Mechanical Engineering, Physics, or equivalent
• Experience with organ perfusion in a research or clinical context
• Experience working in a startup

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

$120,000 - $200,000 a year
