Job Description

CoreAI 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 help strengthen one of the highest‑scale experimentation platforms - critical infrastructure that enables rapid iteration in AI systems and product features. You will contribute to 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 solving complex distributed systems challenges, learning experimentation fundamentals, and building reliable infrastructure that accelerates Microsoft’s progress in AI.

  • Run experiments end-to-end: formulate hypotheses, implement engine changes (including Python/PyTorch integration points where relevant), analyze results, and ship improvements behind guardrails.
  • Build and use experimentation capabilities for large-scale AI inference (experiment lifecycle, tracking, metric modeling, comparability standards, automated analysis) so the team can iterate quickly and safely.
  • Own serving availability and efficiency for Azure OpenAI Service workloads through tiered experimentation, lean segmentation, and multi-modal utilization across heterogeneous fleets—turning findings into shipped engine improvements.
