About Polymath

Simulation environments to train & evaluate long-horizon AI agents. Backed by Y Combinator.

About the role

We’re hiring Software Engineers to build the simulation environments, tasks, and verifiers that challenge frontier models. You’ll help create the training and evaluation grounds that make it possible to measure and improve autonomous agents on realistic, challenging work.

More about this role

Polymath is an applied research lab focused on advancing long-horizon agent capabilities through reinforcement learning. We design and scale simulation environments where agents learn to operate safely and autonomously. We work with the world’s leading model labs to push the frontier of agent capabilities. We've raised >$8M from Base10, Founders Future, Y Combinator, and other incredible investors & angels.
