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. ### 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
