The Opportunity

We are hiring a Senior Business Data Scientist to join our Impact Measurement team. This is a senior individual contributor role focused on causal inference, applied research, and strategic analytics for one of the largest creator and video ecosystems in the world. You will work closely with executives, business leaders, and cross-functional partners to shape the questions we ask, the methods we use, and the answers we deliver.

This role is ideal for someone who enjoys a blend of hands-on analytical work, research design, peer collaboration, and high-stakes storytelling. You will spend your time designing observational and experimental studies, writing code to analyze massive datasets, reviewing causal work from other teams, and presenting clear, honest, and actionable insights to senior stakeholders.

Key Responsibilities

• Lead Causal Research: Design and lead rigorous causal studies—both experimental and observational—to answer high-impact business questions. Translate vague strategic questions into well-defined measurement problems.
• Drive Analytical Strategy: Partner with business, product, and operations leaders to define metrics, measurement frameworks, and analytical roadmaps that shape the company’s most important decisions.
• Present to Executives: Communicate findings, recommendations, and uncertainty clearly to senior leaders, non-technical audiences, and cross-functional partners. Make complex analyses accessible and actionable.
• Peer Review and Quality Control: Serve as a peer reviewer for causal research designed by other analytics and data science teams, helping to raise the methodological bar across the organization.
• Develop and Apply New Methods: Stay current with advances in causal inference, econometrics, and applied statistics. Develop new techniques when existing methods are not sufficient.
• Build Reusable Tooling: Contribute to internal libraries, frameworks, and documentation that make high-quality causal analysis faster and more reproducible for the broader team.
• Mentor and Collaborate: Coach junior analysts and data scientists on research design, statistical thinking, and effective communication. Collaborate across time zones and disciplines.

Minimum Qualifications

• Master’s degree in Computer Science, Statistics, Mathematics, Economics, Applied Data Science, Machine Learning, or a closely related quantitative field—or equivalent practical experience.
• Experience articulating business and product questions and translating them into analytical problems.
• Strong proficiency in SQL and at least one statistical programming language such as R, Python, SAS, Stata, or MATLAB.
• Hands-on experience with data analysis through internships, research, or professional roles.
• Solid understanding of experimental design, A/B testing, and statistical inference.

Preferred Qualifications

• Experience with Bayesian hierarchical models, Bayesian Additive Regression Trees (BART), Bayesian Causal Forest (BCF), Gaussian Processes, and Synthetic Control methods.
• Experience designing and analyzing randomized controlled trials at scale.
• Experience designing and analyzing causal research using observational data, including techniques for handling confounding, selection bias, and treatment heterogeneity.
• Deep expertise in statistical data analysis, including linear and generalized linear models, multivariate analysis, stochastic models, and modern sampling techniques.
• Track record of presenting analytical work to executive and non-technical audiences.
• Publications, conference talks, or open-source contributions in causal inference, econometrics, or applied statistics are a strong plus.

Skills and Competencies for Success

• Research Design: You know how to design a study that answers the question being asked—not just the question that is convenient to answer.
• Statistical Depth: You are comfortable reasoning about assumptions, biases, variance, and uncertainty. You can defend your methods and acknowledge their limits.
• Business Acumen: You care about the decision the analysis is meant to inform, not just the technical elegance of the model.
• Communication: You can write a clear narrative around a complex analysis and present it confidently to executives.
• Curiosity and Humility: You are always learning, always questioning, and always open to being wrong in service of getting it right.
