💻 Role 

We’re looking for a Manager, Data Science to lead a high-impact team working on core marketplace problems. In this role, you’ll own measurement, experimentation, and analytical strategy across some of our most important growth, discovery, and ecosystem questions, helping drive durable, profitable GMV across the marketplace.

This is a hands-on leadership role. You’ll manage and develop a strong team of data scientists while also staying close to the work yourself—shaping methodology, raising the quality bar, and helping the company make better product and investment decisions. Depending on business needs and candidate fit, this role may support buyer or seller domains.

• Lead a team of data scientists working on high-impact marketplace problems across areas such as growth, discovery, incentives, ads, ranking, and ecosystem health

• Build and operationalize strong measurement foundations, including KPI frameworks, dashboards, diagnostics, and recurring business review rhythms

• Raise the bar for experimentation quality through better test design, guardrails, observability, and interpretation

• Partner closely with Product, Engineering, Marketing, Finance, Trust & Safety, and other cross-functional teams on complex marketplace and growth problems

• Drive analytical strategy for major product and business investments, helping teams understand performance, profitability, and tradeoffs

• Support work on discovery, personalization, matching, and monetization across evolving parts of the marketplace

• Improve how teams use data by building scalable frameworks, self-serve analytics, and high-quality analytical assets

• Help your team adopt modern tooling, including AI-enabled workflows, to improve speed, leverage, and decision-making

• Manage, coach, and develop high-performing data scientists while hiring thoughtfully as the business grows

• Nice to have:

  • Experience in marketplaces, two-sided platforms, or live/social consumer products

  • Experience with incentives, pricing, LTV, ads, marketplace health, or ecosystem economics

  • Background in ranking, recommendations, personalization, or growth experimentation

  • Experience building approaches, tools, or methodologies that scaled beyond your immediate team

We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our New York, Seattle, San Francisco or Los Angeles hub.
