[2025] Data Scientist, Ecosystem and Learning Platform - PhD New Grad - Roblox

The Data Science & Analytics organization's mission is to increase our speed, frequency, and acumen in making decisions at scale by instilling a data-influenced approach to building products. We cover a wide area of the data spectrum, including analytical data engineering, product analytics, experimentation, causal inference, statistical modeling, and machine learning. Aligned and partnering with product verticals, we use this extensive tool belt to discover new opportunities and unmet use cases, influence and shape the product roadmap and prioritization, build data products, and measure impact on our community of players and developers.

The mission of the Ecosystem and Learning Platform Data Science team is to empower our data science organization and drive data-informed decision-making at scale. We do so by collaborating within data science and cross-functional partners to solve complex business problems that span multiple areas of the Roblox ecosystem, develop scalable solutions and tools, and advance data science methodologies. Central to our mission is an experimentation and insights platform that provides comprehensive solutions for company-wide experimentation needs, integrates diverse data sources, and offers scalable, accessible data science products that yield actionable insights for product areas across Roblox.

As a member of this team, you will be essential to ensuring the successful execution of hundreds of experiments on the platform. This is an exciting opportunity to collaborate with product data science partners to bring structure and innovative solutions to complex business problems. In the process, you will contribute to building cutting-edge methodologies and tools that advance data science within our company and set industry standards. If you are a self-starter who is curious and passionate about leveraging big data to create tangible business value and thrive in a dynamic, collaborative, and innovative environment, this is the place for you!
