Member of Technical Staff, Hardware Architecture

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 architect to carry our unit from a completed v1 design to a first article: subsystem boundaries, vendor reality, and every decision between a spec and a machine.

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

• Own the system architecture of the unit across electrical, mechanical, and thermal domains
• Drive make-versus-buy and vendor selection for the first build
• Design for a product line that spans a desk, a home, and a data center

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

We offer a base salary of $180,000 to $320,000 USD and a meaningful equity grant, depending on experience and background, along with competitive benefits.
