Job summary

Until Labs seeks hands-on engineers and physicists to own the interface between a high-power rewarming platform and biological samples. You will design hardware and software that connect holders, fluidics, sensing, control, and data acquisition, while running experiments with real organs in the lab.

Ideal candidates have 3+ years of hands-on engineering experience, strong fundamentals in electromagnetics and heat transfer, and proficiency in Python or C++.

Qualifications

• 3+ years of hands-on engineering experience (student teams count), and a project you can walk us through in depth: the reasoning and where your first model was wrong.
• Strong command of electromagnetics, heat transfer, and fluid dynamics.
• Mechanical design and fabrication experience (CAD, rapid prototyping, 3D printing, etc.).
• Circuit design experience from protoboard to PCB, plus building and debugging sensors, data acquisition, and control systems.
• Proficient in object-oriented programming in Python and/or C++.
• Eager to work closely with biologists (no biology background required).
• Desire to join a small, fast-paced team on an excellent adventure.

Responsibilities

• Design, build, and operate the hardware and software linking the rewarming system and the organ: holders, fluidic circuits, sensing, control, and data acquisition.
• Run experiments on holder designs and rewarming protocols alongside the organ and cryobiology teams.
• Reason from first principles, using electromagnetics, heat transfer, imaging and measurement data, to model nanoparticle distribution and heating uniformity, then refine hardware and protocols.
• Develop sensing, control, interlock, and logging software for field profiles and temperature feedback.
• Learn quickly, take ownership of ambiguous problems, and contribute across the full rewarming hardware stack.

Job description

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? Our high-power rewarming platform generates tens of kA/m at MHz frequencies, but that power only matters if it deposits the right amount of heat in the right places inside a vitrified organ. That happens at the interface between the platform and the biological sample, and this role owns it.

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 electromagnetics, fluid dynamics, and heat transfer as they are building hardware and running experiments with real organs in the lab.

What You'd Do

• - Design, build, and operate the hardware and software linking the rewarming system and the organ: holders, fluidic circuits, sensing, control, and data acquisition.


• - Run experiments on holder designs and rewarming protocols alongside the organ and cryobiology teams.


• - Reason from first principles, using electromagnetics, heat transfer, imaging and measurement data, to model nanoparticle distribution and heating uniformity, then refine hardware and protocols.


• - Develop sensing, control, interlock, and logging software for field profiles and temperature feedback.


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