Full 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

- Subsidized lunch daily 120000 - 200000 USD a year
While this represents our expected range based on market data, final compensation will be determined based on your specific qualifications and may be outside this range. Please keep in mind that the equity portion of the offer is not included in this estimate.
