Member of Technical Staff, Firmware

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 a firmware engineer for the software closest to the machine: bring-up, control loops, telemetry, and safe remote update for hardware in other people's buildings.

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

• Own real-time control loops with physical consequences
• Build update mechanisms that never brick a unit in a stranger's home
• Design telemetry that tells the truth about machine health

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.
