Principal Data Scientist- Decisioning

Description

The Enterprise Data & Analytics organization is seeking a Principal Data Scientist to design, build, and improve quantitative models that strengthen customer relationships, improve decision quality, and drive measurable business outcomes.

In this role, you will:

• Lead the development of statistical, machine learning, and causal inference solutions from problem definition through deployment, monitoring, validation, and continuous refinement.

• Evaluate targeting and decision performance using experimentation, counterfactual analysis, quasi-experimental techniques, and observational data to improve customer and business outcomes.

• Develop methods that estimate incremental impact, treatment effects, and heterogeneous customer response to support more effective and economically sound decisions.

• Translate ambiguous business objectives into defensible analytical problems, measurable outcomes, analytical requirements, and practical implementation plans.

• Partner with data science, marketing, product, finance, risk, data, and technology teams to integrate models into governed business processes and production decision systems.

• Synthesize analytic findings into a clear and approachable story and set of recommended actions, reducing complexity as appropriate for different audiences.

• Communicate assumptions, tradeoffs, limitations, and recommendations clearly while maintaining appropriate documentation, controls, and ownership.

• Guide the continuous improvement of analytical systems by incorporating experimental results, operational outcomes, and observed customer behavior into future models and targeting strategies.

A successful incumbent will have:

• Master’s degree in statistics, economics, engineering, computer science, or a related quantitative field; PhD preferred.

• 10+ years of experience applying advanced analytics and delivering models through the full development lifecycle, including deployment, monitoring, governance, and ongoing improvement.

• Deep knowledge of statistical modeling, causal inference, and experimental design, with a demonstrated ability to improve decision quality and targeting through estimation and counterfactual reasoning.

• Experience estimating heterogeneous treatment effects and incremental value using randomized experiments, causal machine learning, quasi-experimental techniques, uplift modeling, and contextual bandits to support customer-level personalization and decisioning.

• Experience designing, executing, and evaluating experiments, including randomization strategy, holdouts, guardrails, outcome measurement, and causal interpretation of results.

• Strong Python and SQL skills (with 5+ years of applied experience each), including experience building reproducible analytical pipelines and working efficiently with large, complex datasets.

• Experience with cloud computing platforms (preferably AWS) and ML-related services such as Amazon Sagemaker.

• Ability to balance analytical rigor, interpretability, implementation complexity, and business usefulness under evolving priorities.

• Strong stakeholder-management and communication skills, including the ability to explain complex analytical, experimental, and causal concepts in clear, unambiguous language.

• Financial services experience and familiarity with related customer-level behavior, profitability, personalization, and relationship analytics preferred.
