What you will do

Drive our research. Shape the direction of in-house research on how consumer LLMs search, reason, and synthesize sources. Stay on top of frontier AEO/GEO research, form hypotheses, and test them with scientific rigor. Your work will be published.
Set the standard for data-driven decision making. Support the product and engineering teams with the analysis and experiments behind key product decisions, from our agent evals to changes in our core analytical pipelines.
Run experimentation and causal inference. Design and analyze experiments, and build measurement even when clean A/B tests aren't possible.
Turn research into a product. A finding about model behavior is only true for the moment it was measured, and the models change constantly. Build the data pipelines and recurring measurement that keep our research live rather than a snapshot, and push the durable findings into the product.
