Responsibilities
Set and land experimentation best practices across Windows. Define and implement clear, practical guidance on experimental design, measurement, and decision frameworks so teams can make faster, higher‑quality decisions
Own experimentation quality systems. Maintain and evolve guardrails, scorecards, and decision mechanisms to deliver trustworthy insights at Windows scale. Lead root‑cause investigations and post‑mortems when results conflict or regressions appear, and drive fixes into practice
Build next‑generation measurement capabilities. Partner with Windows Experimentation colleagues to improve insight generation while reducing manual work through automation and reusable assets
Lead through influence to drive alignment and adoption. Create clarity across Windows PM, Engineering, and Data Science teams; land common practices; reduce duplicated effort; improve decision quality
Multiply impact by developing talent and raising the bar for the craft. Provide hands‑on technical and career mentorship for earlier‑career data scientists; lead reviews and learning sessions; and contribute to hiring practices
Represent Windows Experimentation externally and drive innovation. Share work at academic and industry forums, stay current on advances in experimentation and causal inference, pilot new approaches, and embed successful techniques into practice and the platform
Embody our culture and values
