Senior Data & Applied Scientist

Microsoft • Redmond, WA

20h • $119,800 - $234,700

About The Position

Microsoft's AI for CELA team is part of Corporate, External, and Legal Affairs, which brings together legal, regulatory, public policy, compliance, and corporate affairs professionals. The team is seeking a Senior Data & Applied Scientist to use data science, machine learning, and artificial intelligence to improve how these professionals capture knowledge, manage work, and respond to regulatory change. This role is aligned to the Data Science IC4 career stage.

The position involves framing complex and ambiguous problems, planning projects around risks and constraints, and linking technical measures to meaningful outcomes for legal professionals, business clients, and engineering teams. The scientist will build AI-enabled knowledge-management capabilities that turn fragmented requests, guidance, communications, and work product into structured, governed, reusable institutional knowledge. Areas of work include intake and triage, search and summarization, draft guidance, insight extraction, and decision support integrated into CELA tools and workflows.

The role also develops AI solutions for ongoing regulatory intelligence: detecting and prioritizing regulatory changes, extracting and structuring requirements, mapping changes to obligations, policies, products, and controls, and producing traceable impact assessments for expert review. Success depends on technical judgment, collaboration with legal and regulatory experts, disciplined evaluation, human-in-the-loop design, clear communication, and responsible, secure, auditable AI.

Requirements

• Doctorate in Data Science, Mathematics, Statistics, Econometrics, Economics, Operations Research, Computer Science, or a related field and at least 1 year of data-science experience; or master's degree in one of these fields and at least 3 years of experience; or bachelor's degree in one of these fields and at least 5 years of experience; or equivalent experience.
• Advanced knowledge of statistical analysis, experimentation, algorithms, machine learning, and AI, and experience selecting and applying methods appropriate to the problem, data, and desired outcome.
• Experience managing, transforming, and analyzing structured and unstructured data and developing reproducible solutions using SQL or related query languages and Python, R, or another relevant programming language.
• Experience developing, evaluating, or operationalizing scalable machine-learning or AI systems, including retrieval, natural language processing, large language models, agentic workflows, and quality and impact metrics.
• Ability to own complex projects, make sound decisions amid ambiguity, collaborate across legal, policy, research, product, and engineering disciplines, manage competing constraints, and deliver high-quality results.
• Excellent written, verbal, storytelling, and technical communication skills, including presenting findings to senior technical and non-technical stakeholders and mentoring other practitioners.

Nice To Haves

• Doctorate in Data Science, Mathematics, Statistics, Econometrics, Economics, Operations Research, Computer Science, or a related field and at least 3 years of data-science experience; or master's degree in one of these fields and at least 6 years of experience; or bachelor's degree in one of these fields and at least 8 years of experience; or equivalent experience.

Responsibilities

• Translate ambiguous legal, knowledge-management, and regulatory problems into objectives, project plans, measurable success criteria, and roadmaps.
• Acquire, assess, and prepare structured and unstructured data from communications, documents, matters, regulatory sources, and operational systems; address data-quality, integrity, privacy, security, bias, and ethical risks.
• 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 connecting technical performance to accuracy, consistency, traceability, adoption, capacity returned, and business value, while leaving legal and regulatory judgment with accountable experts.
• Build partnerships with legal professionals, policy experts, engineers, researchers, and business stakeholders; influence decisions through narratives and visualizations; mentor less experienced practitioners; and establish responsible AI, data, and engineering best practices.

Benefits

• Certain roles may be eligible for benefits and other compensation; additional benefits and pay information is available through the provided Microsoft careers link.
