Overview
Do you want to shape how Windows is built and shipped? Join the team behind the experimentation engine that powers product innovation and deployment decisions. At Windows Experimentation, we help teams move fast and ship smart by delivering trusted insights through randomized controlled trials.
As a Senior Data Scientist on the Windows Experimentation team, you’ll build the statistical and technical foundations that power experimentation across the Windows ecosystem. Your work will enable product teams to test new features with confidence and help engineering and release teams make data-driven decisions about shipping Windows. You’ll collaborate across disciplines to design scalable systems, improve causal inference methods, and ensure that experimentation is fast, reliable, and trustworthy.
This role offers high-impact work at the intersection of science, engineering, and product; a deep focus on experimentation infrastructure, causal inference, and telemetry at scale; and the opportunity to shape how Microsoft builds and ships Windows to more than a billion devices.
