This is a hands-on role for someone who enjoys learning, questioning assumptions, and applying data science to real-world decisions at scale. This is not a "reporting" role. It is a decision-making role, where experimentation, judgment, and AI-enabled workflows come together to shape real outcomes. Microsoft's mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond. Starting January 26, 2026, Microsoft AI (MAI) employees who live within a 50- mile commute of a designated Microsoft office in the U.S. or 25-mile commute of a non-U.S., country-specific location are expected to work from the office at least four days per week. This expectation is subject to local law and may vary by jurisdiction. Responsibilities * Experimentation & A/B Testing + Design, analyze, and interpret A/B experiments end-to-end, from hypothesis formulation to final decision + Choose appropriate metrics, success criteria, and evaluation windows based on user behavior and business context. + Identify and diagnose common experimentation issues (e.g., bias, interference, power limitations, metric sensitivity). + Communicate experimental results clearly, including uncertainty, limitations, and trade-offs. * Decision Science & Insights + Go beyond "did it move the metric?" to explain why results happened and what decision should be made + Combine experimental evidence with observational analysis when appropriate + Partner closely with product, engineering, and design stakeholders to influence direction using data * AI-First Analytical Work + Use AI tools to accelerate analysis, exploration, and insight generation (e.g., faster hypothesis testing, code generation, narrative summaries). + Continuously evaluate where AI can improve experimentation workflows, without compromising rigor or correctness. + Develop good judgment about when to rely on automation vs. when deep statistical reasoning is required. * Learning & Craft Development + Stay current on experimentation methods, causal inference, and applied statistics. + Learn and adopt new tools, techniques, and best practices quickly. + Contribute to shared standards and documentation that improve how teams run experiments and make decisions. ## Related Videos - [Inside the AI Revolution: How Microsoft is Empowering the World to Achieve More](https://www.wearedevelopers.com/videos/869-inside-the-ai-revolution-how-microsoft-is-empowering-the-world-to-achieve-more) - [Bringing the power of AI to your application.](https://www.wearedevelopers.com/videos/1010-bringing-the-power-of-ai-to-your-application) - [Leapter: The Reinvention of Software Development?
