Senior Data Scientist, Experimentation

ABOUT THE TEAM + ROLE

We are building an elite team, applying frontier technologies to the world's biggest financial problems. We're looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. Robinhood isn't a place for complacency, it's where ambitious people do the best work of their careers. We're a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards.

The Experimentation Platform team at Robinhood builds the systems and infrastructure that power our company-wide experimentation efforts. Our mission is to enable rapid, trustworthy, and statistically sound experimentation at scale, so teams can learn quickly and make confident decisions. We partner closely with engineering, product, and data teams across the company. The team's work has a direct impact on product velocity and business outcomes. Together, we're driving a culture of data-informed innovation across Robinhood.

As a Senior Data Scientist on the Experimentation Platform team, you'll play a key role in shaping the statistical foundations of our experimentation systems. You'll collaborate closely with engineering, product, and data partners to advance best practices in A/B testing, improve experiment velocity, and build capabilities that help Robinhood scale experimentation effectively. You'll also explore how AI-powered capabilities can automate workflows and strengthen decision-making, while serving as a trusted statistical partner to data science and product teams. This is a high-impact role with the opportunity to define how we learn and iterate across our products!

This role is based in our Menlo Park, CA office, with in-person attendance expected at least 3 days per week.
