Member of Technical Staff, Telecom and RF Systems

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 for telecom-grade equipment that lives inside our units: radio, switching, and the compliance path to ship them into homes and businesses.

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

• Design spectrum-agile RF front ends and antennas for telecom workloads
• Own emissions, certification, and coexistence for equipment in occupied buildings
• Make radio and switching performance measurable and honest

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.
