As a Senior Research Engineer at Microsoft, you will advance Microsoft’s mission to empower every person and every organization to achieve more. You will help build and integrate cutting-edge AI into Microsoft products and services within the Business & Industry Copilot (BIC) group, ensuring solutions are inclusive, ethical, and impactful. This role blends applied research, machine learning engineering, and product innovation. You will lead efforts to ship reliable, production-grade AI systems across the stack, from model development and fine-tuning to performance optimization and deployment.

Design and implement AI systems using foundation models, prompt engineering, retrieval-augmented generation, multi-agent architectures, and classic ML.

Fine-tune large language models on domain-specific data and evaluate via offline and online methods such as A/B testing, telemetry, and shadow deployments.

Build and harden prototypes into production-ready services using robust software engineering and MLOps practices.

Drive original research and thought leadership (whitepapers, internal notes, patents); convert insights into shipped capabilities.

Research Translation: Continuously review emerging work; identify high-potential methods and adapt them to Microsoft problem spaces.

ML Design & Architecture: Own end-to-end pipeline from data prep, training, evaluation, deployment, and feedback loops.

Identify and resolve model quality gaps, latency issues, and scale bottlenecks using PyTorch, or TensorFlow.

Operate CI/CD and MLOps workflows including model versioning, retraining, evaluation, and monitoring.

Integrate AI components into Microsoft products in close partnership with
