# Electrical Engineer / Applied Physicist

**Until** · Bay Area

Salary: $120,000–$130,000 per year

Apply: https://jobs.lever.co/until/b75143f0-9da0-4b95-b4ca-68b098afe17b

## About the 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 for delivering high power into complex biological loads.

We are looking for fast-moving, hands-on engineers and physicists with strong fundamentals, high autonomy, and a desire to build technology that feels impossible until it works. This role is for someone who is as comfortable deriving a back-of-the-envelope model from circuit laws, electromagnetics, and thermal physics as they are wiring up hardware in the lab.

##### 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.

- Reason from first principles, using circuit theory, electromagnetics, thermal physics and measurement data, to model system behavior and debug ambiguous hardware problems

- 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:

- You have a strong command of circuit theory and physics (impedance, resonance, energy storage, electromagnetics, and heat transfer), and you reach for these instinctively when a piece of hardware isn’t behaving as expected.

- You have a project you can walk us through in depth: not just what you built, but the physics and math reasoning that got you there, and where your first mental model was wrong.

- You can make order-of-magnitude estimates quickly, and you can explain the physical intuition behind them clearly to someone else.

- You’ve designed, built, and debugged real analog and digital circuitry, taking systems from schematic to bench and through bring-up.

- You have experience with basic control systems, instrumentation, data analysis, and hands-on experimental hardware.

- You have a BS/MS in EE, Physics, or equivalent self-taught depth; we care more about demonstrated reasoning ability than credentials.

- You want 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
