About This Role

About the Company:

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:
One of the key unsolved challenges in cryopreservation is the rewarming problem: how do we rapidly and uniformly rewarm whole organs and, ultimately, whole bodies to restart cryopreserved biology? One of the key ingredients is building first-of-its-kind electrical systems. Doing so requires a fast-paced, scrappy team of electrical engineers and physicists who want to make technology indistinguishable from magic. 

What You'd Do:

  • Design, build, test, and debug electrical hardware for organ rewarming systems.

  • Develop power converters, resonant matching networks, instrumentation and control systems.

  • Build test fixtures, data acquisition systems, experimental setups and control software for high-power hardware validation

  • Learn quickly, take ownership of ambiguous problems, and contribute across the full rewarming hardware stack.

  • About You:

  • Strong fundamentals in physics and electrical engineering.

  • Experience designing, building and debugging both analog and digital circuitry.

  • Experience with basic control systems and mechanical design.

  • Demonstrations of exceptional ability and autonomy in past work.

  • Desire to join a small, fast paced team on an excellent adventure.

  • Benefits:

  • Generous medical, dental and vision insurance coverage

  • 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

  • Daily lunch and dinners, plus a variety of snacks 

  • Monthly learning stipend

  • On-site fitness center

  • Quarterly team social budget

    Join our team and be part of the future of medicine and technology.
