Role Overview

As part of the Enterprise Data & Analytics team, the Senior Business Data Analyst - Planning & Modeling is responsible for leading functional analysis and conceptual solution design scenario planning, predictive modeling, and advanced analytics use cases.

This role focuses on bridging business-driven modeling needs with technical implementation-partnering with Analytics and business teams to understand modeling methodologies, assumptions, and decisioning requirements, and translating them into scalable, reusable frameworks built on modern data platforms.

Acting as the connective layer between model designers, end users, and engineering teams, this role ensures that models are not only analytically sound, but also operationalized as robust, scalable data solutions that drive consistent, enterprise-wide decision-making.

Key Responsibilities Scenario Planning & Predictive Modeling

• Partner directly with model designers and end users to understand how models are constructed, used, and drive decision-making.
• Translate modeling approaches, assumptions, and workflows into clear functional requirements and structured logic for implementation by engineering teams.

• Act as the primary liaison between business stakeholders and engineering, ensuring models are accurately represented, scalable, and reusable within the data platform.
• Lead requirements discovery and facilitation for modeling use cases.

Delivery Partnership & Execution Support

• Partner with data engineering to operationalize models in the data lake and pipelines.
