Job Description:

We’re hiring a Principal Data Scientist to help reimagine Copilot Search & Agents—turning search into action with AI that understands context, summarizes content at a glance, and helps users move work forward instantly. You’ll ship ML that reaches hundreds of millions and fuels real productivity gains, while publishing, filing patents, and working on truly cutting‑edge tech.

Job Responsibility:

  • Design and ship ML for semantic search, summarization, entity/topic understanding, and related‑content discovery that turns “find” into “know in a glance.”
  • Build evaluation frameworks (online + offline) and run rapid experimentation to improve relevance, trust, and user productivity.
  • Partner across Eng/PM/Design to productionize models in low‑latency, high‑reliability services powering Copilot Search and Agent workflows.
  • Leverage connectors and extensibility patterns to ground models in first‑ and third‑party systems (Graph connectors, plugins), all under Microsoft’s security, privacy, and responsible AI standards.
  • Contribute to publications, patents, and open collaboration—share results at top venues and translate research into features that help users get real work done.

Requirements:

  • Doctorate in Data Science, Mathematics, Statistics, Econometrics, Economics, Operations Research, Computer Science, or related field AND 5+ years data-science experience
  • OR Master's Degree in Data Science, Mathematics, Statistics, Econometrics, Economics, Operations Research, Computer Science, or related field AND 7+ years data-science experience
  • OR Bachelor's Degree in Data Science, Mathematics, Statistics, Econometrics, Economics, Operations Research, Computer Science, or related field AND 10+ years data science experience
  • OR equivalent experience
  • Depth in NLP/IR/LLMs/RAG, and/or Graph/representation learning
  • strong fundamentals in causal inference or experimentation a plus
  • Proficiency in Python (and one of: C#/Java/Scala), data tooling (e.g., PyTorch/Transformers, Spark/SQL), and production ML practices
  • Experience optimizing latency, reliability, and cost for AI services in cloud environments (Azure preferred)
  • Evidence of thought leadership (papers, patents, OSS, talks) and cross‑discipline collaboration
  • Passion for product impact: you care about measurable gains in user productivity and quality

Nice to have:

  • Prior work on enterprise search, recommendations, summarization, or agents
  • familiarity with Copilot extensions/Graph connectors
