Microsoft is considered one of the leaders in Software as a Service in the world of business applications and this organization is at the heart of how business applications are designed and delivered.

This is an exciting time to join the **Business and Industry Solution** s **(BIS)** and work on something highly strategic to Microsoft in shaping the future of the autonomous enterprise and lead the development of intelligent, agent-first experiences that transform how businesses operate. The Business and Industry Solutions (BIS) team is looking for a Applied Scientist II to drive innovation at the intersection of AI, experimentation, and enterprise systems. In this role, you will design and evaluate autonomous agents that deliver measurable improvements in accuracy, latency, and cost-efficiency. You’ll lead rapid experimentation cycles, develop robust evaluation frameworks, and apply advanced techniques like reinforcement learning to enable multi-step reasoning and decision-making. You’ll collaborate across engineering, product, and partner teams to ensure agents are performant, secure, reliable, and extensible—empowering customers and partners to build on our platform. This is your opportunity to influence the next generation of AI-native business applications and deliver real-world impact at scale.

We are looking for an **Applied Scientist II** to join our team!

The ideal candidate has prior expertise in natural language processing (NLP), with a foundation in large language model (LLM) development, evaluation, and fine-tuning. They should have experience in applying advanced fine-tuning techniques—including instruction tuning, reinforcement learning from human feedback (RLHF), and tool-augmented generation—to build agents capable of multi-step reasoning and decision-making. Familiarity with prompt/context engineering, context-aware orchestration, and integrating LLMs with external tools and APIs is essential. The candidate should be comfortable working in a experimentation-driven environment, leveraging both offline and online evaluation methods to iterate rapidly and optimize agent behavior. A understanding of the challenges and opportunities in building AI-native enterprise applications will be key to success in this role.
