Member of Technical Staff, Microfluidics

Threeum

Threeum is a frontier company building physical AI. We design the model and the machine as one system, so the full loop of training, deployment, and improvement runs faster, more capable, and more autonomous. Our goal is to make frontier AI physical, and to make it widely accessible.

The Role

We are looking for an engineer-scientist for fluid handling inside sealed machines: supplying a dense three-dimensional volume reliably, for years, without attention.

Some example areas you might work on (not limited to):

• Design microfluidic delivery and exchange for dense volumetric structures
• Solve clogging, bubbles, and degradation for maintenance-free operation
• Integrate fluidics with electronics and manufacturing rather than around them

If you want to build the machines the models deserve, we would love to hear from you.

We offer a base salary of $250,000 to $400,000 USD and a meaningful equity grant, depending on experience and background, along with competitive benefits.
