Senior Applied Scientist

Microsoft Microsoft · Big Tech · Redmond, WA +1 · Applied Sciences

Senior Applied Scientist role focused on building the core systems for Microsoft Copilot for enterprise, working on orchestrator reasoning, training next-generation models, and shipping model-driven experiences. The role involves advancing agent-based systems, multi-modality, and post-training methods like fine-tuning and reinforcement learning, as well as model development, evaluation, and A/B testing.

What you'd actually do

  1. Evolve our orchestrator to reason more effectively, respond faster, and support new capabilities in multi-modality, agent-based systems, and beyond
  2. Advance the state of the art in model training—including post-training methods such as fine-tuning and reinforcement learning, high-quality data curation, and experimentation with frontier model training
  3. Build and deliver model-driven features from concept to production—spanning model development, evaluation, metrics, and A/B testing
