Electrical Engineer

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.
