Electrical Engineer

UntilUntil 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 RoleOne 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 validationLearn 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 coverageFlexible time off and paid holidaysCompetitive compensation package, including salary and equityAccess to a 401(k) retirement savings planFSA and commuter benefitsDaily lunch and dinners, plus a variety of snacksMonthly learning stipendOn-site fitness centerQuarterly team social budget$120,000 - $130,000 a year
