Sr. Mechanical Engineer, Fluidics/Perfusion
Bay AreaOn-siteFull-time
AI Summary
Senior mechanical engineer leading multidisciplinary teams to design heat/mass transfer systems for organ perfusion and cryopreservation devices.
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 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.
