Sr. Mechanical Engineer, Fluidics/Perfusion

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 the Role** Accomplishing our mission requires skilled engineers pushing the boundary developing new systems for heat and mass transfer in N-of-1 perfusion and heat exchange devices. We're building a fast-paced, scrappy team of engineers to create technology indistinguishable from magic. ### About You - Track record of exceptional engineering abilities - Experience leading highly technical, multidisciplinary teams - 3+ years experience/graduate level in Mechanical Engineering, Physics, or equivalent - Deep understanding of heat and mass transfer principles alongside fluidic design experience - 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 - 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
