About the role

Senior Data & Applied Scientist to apply advanced data science, machine learning, and AI to transform knowledge capture, management, and regulatory intelligence for Microsoft’s AI for CELA team within Corporate, External, and Legal Affairs (CELA).

Responsibilities

  • Own complex data science engagements by translating ambiguous legal, knowledge-management, and regulatory problems into clear objectives, project plans, measurable success criteria, and roadmaps that improve outcomes over time.
  • Acquire, assess, and prepare structured and unstructured data from communications, documents, matters, regulatory sources, and operational systems; identify data-quality, integrity, privacy, security, bias, and ethical risks; and establish reliable data foundations for AI.
  • Design, develop, and evaluate statistical, machine learning, and generative AI approaches for classification, routing, retrieval, summarization, knowledge drafting, metadata extraction, regulatory monitoring, requirements extraction, and impact analysis.
  • Write efficient, readable, extensible, production-quality analysis and software code; diagnose complex issues; prototype and operationalize scalable solutions; and partner with engineering teams on deployment, monitoring, maintenance, and continuous improvement.
  • Define evaluation metrics and human-review workflows that connect technical performance to accuracy, consistency, traceability, adoption, capacity returned, and business value, while ensuring that legal and regulatory judgment remains with accountable experts.
  • Build trusted partnerships with legal professionals, policy experts, engineers, researchers, and business stakeholders; influence decisions through clear narratives and visualizations; mentor less experienced practitioners; and establish responsible AI, data, and engineering best practices across the team.
