Senior Applied Data Scientist

Join M365 AI Experiences Data Platform to build the privacy first, experimentation driven data intelligence platform powering M365 Agents, People Experiences, and Windows Companions Apps. As we launch new capabilities across the ecosystem, you'll turn raw, privacy safe signals into unified telemetry and actionable insights that let us ship faster through continuous experimentation, helping millions accomplish more every day. From industry leading "eyes off" analytics and deep behavioral understanding to mapping cross app workflows and measuring real productivity gains, you'll architect the end to end foundation that product teams use to learn fast, decide with confidence, and build better. If you're obsessed with software craftsmanship and responsible innovation at massive scale, come shape how M365 understands its users, and convert that understanding into intuitive, high value experiences from first instrument to final decision.   We are seeking a Senior Applied Data Scientist to join our high-velocity data platform team, driving measurable business impact through advanced experimentation, analytics, and machine learning solutions. This role is end-to-end, transforming ambiguous business questions into production-ready models and data workflows. You will partner closely with product and engineering teams to accelerate learning, improve decision-making, and deliver scalable, privacy-preserving solutions that uphold enterprise standards.

As a key contributor, you will lead the design and analysis of rigorous A/B tests, implement causal inference methodologies, and develop privacy-aware analytics pipelines. You will own the full lifecycle from prototyping and validation to deployment and monitoring, while ensuring performance optimization and alignment with business KPIs. Your work will involve building high-throughput ETL workflows, integrating APIs, and maintaining robust data quality and compliance frameworks.

Beyond technical execution, this role emphasizes collaboration and leadership. You will embed with cross-functional teams, mentor junior talent, and champion best practices in experimentation, data engineering, and operational excellence. This is a mission-critical opportunity to shape the future of our data platform, influence strategic decisions, and drive rapid product learning at scale in a culture that values innovation, psychological safety, and continuous growth.
