OverviewCoreAI sits at the center of Microsoft's mission to redefine how software is built and experienced, providing the foundational platforms, services, and developer experiences that power the next generation of AI-driven applications. As part of CoreAI, the Experimentation Platform (ExP) enables trustworthy, high-scale online experimentation that accelerates product learning and drives progress across Microsoft's AI ecosystem. You will play a key role in helping teams ship better AI experiences faster by providing the experimentation capabilities needed to evaluate, refine, and safely deploy new innovations.
In this role, you will own and drive the development of critical components in one of the highest-scale experimentation platforms - infrastructure that enables rapid iteration in AI systems and product features. You will design and build services that empower engineers and scientists across the company to measure impact, validate hypotheses, and advance state-of-the-art AI capabilities through rigorous experimentation. This is a unique opportunity to build systems at scale while deepening your expertise in distributed systems, service reliability, and experimentation methodologies. You will thrive in this role if you enjoy driving technical excellence in distributed systems, mentoring engineers, and building reliable infrastructure that accelerates Microsoft's progress in AI.
Microsoft's mission is to empower every person and every organization on the planet to achieve more, and we're dedicated to this mission across every aspect of our company. Our culture is centered on embracing a growth mindset and encouraging teams and leaders to bring their best each day. Join us and help shape the future of the world.
ResponsibilitiesResponsibilities- Independently leverage AI tools and practices across the software development lifecycle (SDLC), taking responsibility for AI-generated assets and coaching team members to adopt responsible AI-assisted development practices.
