Principal Applied Scientist [Remote]

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Principal Applied Scientist based in the United States.

We are seeking an experienced Principal Applied Scientist to lead the development of a rigorous evaluation framework for enterprise AI agents. In this research-intensive, customer-facing role, you will work closely with engineering teams to assess planner models, execution models, and inference optimization strategies through controlled, statistically sound experiments. You will own both the experimental methodology and the production-quality tools that make evaluation repeatable, from realistic user simulation and isolated experiment execution to statistical analysis and automated insights. Your work will help distinguish meaningful improvements from inconclusive results, quantify the relationship between quality and cost, and translate technical findings into measurable business value. You will also provide technical leadership, establish evaluation standards, and deliver actionable recommendations that support enterprise deployment decisions.
