About the job
Designs and improves systems that create realistic synthetic agents and simulate population-level behavior for decision-making.
What you'll do
- Develop methods and pipelines to synthesize agents from profile data and produce accurate population-level distributions.
- Ground agent behavior in real-world data and design architectures combining LLMs with computational social science, psychometrics, and survey methods.
- Evaluate simulations against ground-truth data and iteratively reduce gaps between simulated and observed behavior.
What they ask for
- Deep experience with synthetic data generation, agent-based modeling, computational social science, or population simulation.
- Interest in using LLMs to produce structured behavioral outputs that withstand statistical scrutiny.
- PhD in ML, computational social science, cognitive science, statistics, psychometrics, or a quantitative field—or equivalent depth from industry research.
- Clear communication and ability to work quickly while maintaining rigor.
Nice to have
- Built systems that generate or evaluate synthetic populations at scale; experience with survey methodology, psychometrics, or demographic modeling.
- Published work on agent-based simulation, synthetic data, or LLM-based behavioral modeling; experience in a high-velocity research environment.
Tools
LLMs, GSS
