Overview
We are looking for a Principal AI Architect to help define, build, and scale the evaluation systems that shape the future of AI products. This role sits at the intersection of engineering, applied science, product architecture, and AI evaluation. The ideal candidate has deep technical judgment, strong systems thinking, hands-on experience evaluating LLMs, and the ability to translate emerging AI capabilities into reliable product experiences.
This role is especially important for agentic AI systems, where product behavior is often nondeterministic, context-dependent, and difficult to evaluate with traditional testing alone. The person in this role will help teams build a deep understanding of how agents behave, where they succeed, where they fail, which gaps matter most, and where those gaps should be addressed: in prompts, tools, orchestration, retrieval, ranking, product UX, safety systems, or core code.
The Principal AI Architect will make AI product quality measurable, actionable, and deeply integrated into how teams build and ship. They will help teams evaluate product direction before code is complete, validate quality before launch, and continuously measure performance after release.
They will give teams confidence in how agentic systems behave, where nondeterminism creates risk, which gaps matter, and where to address them. Their work will ensure that evaluation is not an afterthought, but a core part of the product lifecycle, engineering system, and release decision process.
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.
