About The Position

Lead the centralization of testing and measurement at Sam's Club by building a single experimentation and measurement platform and launching self-service tools that empower associates to run high-quality experiments independently. Starting with in-club measurement and moving to Omni you'll establish scientific standards, governance, and guardrails that make results trustworthy and repeatable. You will translate complex data into clear, actionable decisions, mentor a high-performing team, and partner across Product, Engineering, and the business to drive measurable business impact-while reserving your team's deep expertise for the most complex use cases.

Committed to production-grade practices including code quality, automated testing, reproducibility, and model lifecycle management (MLOps).
• Business Acumen & Storytelling: Ability to translate noisy signals into clear decisions; influence senior leaders with concise narratives that connect experiments to member outcomes and financial impact.
• Leadership & Change Management: Experience building and mentoring teams, driving cross-functional adoption, and moving organizations from fragmented practices to consistent standards and self-service at scale.
