About The Role

Thomson Reuters Legal is seeking a Lead Data Scientist to help power data-driven growth and adoption of our AI-enabled legal solutions.

• Use behavioral, usage, firmographic, and lifecycle data to identify signals that indicate readiness for AI adoption and expansion.
• Partner with Lifecycle Marketing to translate model outputs into actionable segments and testable hypotheses across the customer lifecycle.
• Collaborate closely with Marketing Operations to operationalize models within the Customer Data Platform (Treasure Data) for activation and measurement.
• Develop features and datasets using product usage data, campaign engagement, learning activity, and customer attributes.
• Validate, monitor, and continuously improve model performance, ensuring accuracy, explainability, and alignment to business outcomes.
• Document modeling approaches, assumptions, and outputs to enable transparency, reuse, and cross-functional understanding.
• Support experimentation by defining success metrics, analyzing lift, and interpreting results to inform optimization decisions.

Requirements

• 5+ years of experience in data science, analytics, or applied machine learning in a B2B SaaS or subscription-based environment.
• Experience building predictive or classification models that influence customer growth, retention, or expansion decisions.
• Strong proficiency in Python or similar data science tools, including feature engineering and model evaluation.
• Demonstrated experience working with large, complex datasets such as product usage, behavioral logs, or campaign data.
• Experience partnering with Marketing, Growth, or Customer Success teams to translate insights into action.
• Familiarity with deploying or activating models within analytics platforms or CDPs; experience with Treasure Data or similar platforms is a plus.
• Strong understanding of experimentation, model validation, and measuring impact using both statistical and business metrics.
• Ability to clearly communicate technical concepts and insights to non-technical stakeholders.
• Curiosity and ownership mindset, with a strong bias toward building models that are used and deliver measurable outcomes.

Qualifications

• Master's degree in Computer Science, Statistics, Mathematics, or a related field.
• Proven track record of successful data-driven initiatives and projects.
• Experience with machine learning frameworks such as TensorFlow, PyTorch, or Scikit-Learn.
• Knowledge of data warehousing technologies and SQL.
