Overview
Generative AI is transforming how people create, collaborate, and communicate—redefining productivity across Microsoft 365 for customers worldwide. At Microsoft, we operate one of the largest collaboration and productivity platforms in the world, serving hundreds of millions of consumer and enterprise users. Delivering these AI experiences at scale requires solving some of the hardest efficiency challenges in modern AI systems.
We are an applied research team focused on advancing efficiency across the AI stack, spanning models, ML frameworks, cloud infrastructure, and hardware. We drive mid- and long-term product innovation through close collaboration with research and product teams across the company. We communicate our research both internally and externally through internal technical reports, academic conference publications, open-source releases, and patents. Beyond producing research, we take responsibility for driving ideas through prototyping, validation, and production, with a bias toward real-world impact.
The candidate will work across the full stack—from large-scale serving systems to hardware- and kernel-level optimizations—exploring algorithmic, systems, and hardware/software co-design techniques. Areas of focus include batching, routing, scheduling, caching, endpoint configuration, and GPU architecture–aware optimizations. This role emphasizes end-to-end ownership, with responsibility for identifying high-impact problems and driving research ideas through prototyping, validation, and deployment to deliver measurable customer impact.

Responsibilities
- Formulate, develop, and evaluate new algorithmic and system-level approaches for end-to-end AI serving, using analytical modeling and large-scale measurement to study token-level latency, tail latency (p95/p99), throughput-per-dollar, cold-start behavior, warm pool strategies, and capacity planning under multi-tenant SLOs and variable sequence lengths.
- Design and experimentally evaluate endpoint configuration and execution policies, including batching, routing, and scheduling strategies, tensor and pipeline parallelism, quantization and precision profiles, speculative decoding, and chunked or streaming generation, and drive the most promising approaches through robust rollout and validation into production.
- Perform hardware- and kernel-aware optimization by collaborating closely with model, kernel, compiler, and hardware teams to align serving algorithms with attention/KV innovations and accelerator capabilities.
- Build and benchmark experimental prototypes and large-scale measurements to validate research ideas and drive them toward production readiness; produce clear technical documentation, design reviews, and operational playbooks.
- Publish research results, file patents, and, where appropriate, contribute to open-source systems and serving frameworks
Qualifications
Required Qualifications
