Member of Data Staff (Data Scientist)

About this role

Perplexity is AI for people who expect more. This role brings that standard to how we understand our users, shape our product, and decide what to build next.

We're looking for a data scientist who can turn product questions into clear decisions. You'll work across product, engineering, growth, design, and user research to understand user behavior, define metrics, design experiments, and identify the highest-leverage opportunities for the company.

The data team is AI-native by default. We use AI to accelerate analysis, write and review code, explore hypotheses, document data, generate first drafts, and automate recurring workflows. But the core of the role is still judgment: asking the right question, choosing the right metric, designing the right test, and knowing when the answer is strong enough to act on.

WHAT YOU'LL DO

• Develop product insights - analyze user behavior to inform product roadmap, accelerate adoption, and identify opportunities to improve the user experience.

• Design and analyze experiments - form hypotheses, define success metrics, run A/B tests, interpret results, and turn findings into product recommendations.

• Define the metrics that matter - build the metrics, guardrails, dashboards, and reporting workflows that help teams understand product and company health.

• Partner across functions - work closely with engineering, product, growth, design, and user research to answer ambiguous questions and drive decisions.

• Build reusable data assets - create tables, models, and documentation that make analysis faster, more consistent, and easier for humans and AI systems to use.

• Use AI to scale data science - automate recurring analysis, build AI-assisted workflows, improve documentation, and turn one-off investigations into repeatable systems.
