Member of Technical Staff, Bounded Simulation

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 researcher to build simulators with guarantees: bounded-error models of physical systems that the compiler and the safety cases can actually trust.

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

• Build simulators that ship with explicit, validated error bounds
• Verify bounds against hardware measurements as they arrive
• Define the bounded-fidelity contracts the rest of the stack builds on

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.
