Engineer/Applied Physicist

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 We’re building an elite team of applied physicists and engineers for true full stack engineering, from electrons to operating systems. Projects will require high degree of autonomy and breadth of skill across electrical, mechanical, and computational design, with a strong emphasis on first principles thinking and a desire to make technology indistinguishable from magic. About You Strong fundamentals in both a scientific (physics, chemistry, biology) and an engineering (electrical, mechanical, computational) discipline, excited to build the future Experience designing and analyzing both analog and digital circuitry Experience with basic control systems and mechanical design Degree in Electrical Engineering, Mechanical Engineering, Physics, or equivalent Demonstrations of exceptional ability and autonomy in past work Preferred Qualifications 3+ years experience/graduate level in Electrical Engineering, Mechanical Engineering, Physics, or equivalent 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 Flexible time off and paid holidays Competitive compensation package, including salary and equity 401(k) retirement savings plan FSA and commuter benefits Subsidized lunch daily $120,000 - $200,000 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.
