Model Behavior Engineer, Reasoning and Decision Making

You'll join our engineering team and report to an Engineering Manager. You'll work on a cross-functional engineering team, collaborating closely with other engineers, product, design, and domain experts, taking problems from investigation and experimental design through implementation and use in the product.

The work combines careful reasoning, the ability to dive into domain specifics, and software design. You'll design agent environments and how agents represent problems, gather evidence, use tools, retain context, revise their conclusions, and coordinate with each other. You'll also make the engineering decisions that let us inspect those processes, test changes, and build on what works.

Most of the initial work will involve systems built around existing frontier models. Training or finetuning may be useful for particular problems, but the direction of the work will follow what helps users reason better.
